the best angle grinder

[beedigo]

Hi guys, ask lang ako kung ano ang the best na brand na angle grinder sa experience nyo? Thanks: confused:

[JayL]

I have 4 angle grinders ( Makita, Dewalt , Bosch and Maxsell ) . The best one among the lot is the Bosch Variable speed 4" Angle Grinder.

on a woodworking side, i may have to agree with Jay..

i only have a variable speed bosch i purchased in 2007.

there is no other brand offering this feature and it really works for me all the time.

i just screw in the commercial velcro lotus backing pad and attach an 80 grit to start with.

for durability i cannot deny makita. it offers the professional line the price of which is almost double than the regular ones.

it depends on the work you intend to do with them.

if you will be using them for grinding steel forever then buy the most expensive makita.it will serve you well..but then again, running the motor for an hour is enough for them to bog down.

and lastly, dont let someone else borrow your precious tools...buy a ryobi or ozito surplus for your friends..hehe..

you can buy "makata" from the sidewalks of raon as well.

I believe this is meant as one phrase. the makita kasi in the sidewalks are 99% fake and will not last long, but they are cheap...

[beedigo]

Thanks guys, so if the bosch angle grinder has variable speed, does that mean it can be used for bupping up to grinding metal? what model is that? do you have an idea how much it will cost and where to buy?

[pyth]

oi sir beedigo dito kana rin..
I was just thinkin a repeat study bout this time for angle grinder.but too much expensive to do it again... Last year-february- A friend and us made an endurance test study for jigsaw by simultaneously running 7 brands of jigsaw (makita,ryobi,bosch,ozito,skil,dewalt,and fake items from raon). It cost him a lot but he made a point..Continous running until it bogged down..results were obtained and it change my view regarding tools..although it was not necessarily to conclude what ever burnt last should the best best jigsaw..it was only durability test but most user emphasize handling advantage-aesthetic/vibration/etc..bottomline-you have to try it urself to fit your std and need-if not u may depend in branding issue or depend on others user`s advice..

[beedigo]

yup sir pyth, nag join na ko, minsan kasi kelangan ko ng mga advise regarding tools, buti d2 ka rin. magastos pala research nyo sir.
thanks sa advise sir, very enlightening. pero kung home use na marami gamit ano brand ma advise nyo? tnx.

[jonathanscruz68]

sir sa 7 brand of jigsaw you test,which one pass the endurance test?

[timber715]

yup and do specify the model kung pwede. of course endurance doesn't necessitate performance, but it is a plus.

[andrew.hipolito]

hi guys.. im a junior member here... im andrew, i am a foundry supervisor in negros metal corporation.. we use the original makita and dewalt grinders..in my experience. it surpasses durability for steel works and makita jigsaw is the best for wood works..

[timber715]

welcome Andrew to PHM, glad to have pros in this site. can you give us an idea of the Makita jigsaw model you use? I know that Bosch makes the best jigsaws worldwide and know that the newer model Makita (2009 models) seem to be catching up, have you tried the Bosch jigsaw model GST80 PBE or 80PB? if you haven't I'm sure I can ask a representative to visit your plant and give you a demo.
I really can't comment much on the angle grinder since I have little experience using them.

[clayfigur]

Based on my experience,

800w Makita, all purpose, best for metal, tiles, and wood
2200w Ryobi, I use this to cut metal, kinda heavy but powerful
800w Bosch, all purpose, best of metal, and tile cutting
600w kawasaki, strong but light, I use this to clean metal
800w Mac master, strong, but its kinda heavy on the hand
400w china generic, I got 2 of this, I like it co'z its very light, I use it for sanding, minor metal buffing.. (cost only P600 sa Raon)

So far the best I recommend is Makita and Bosch..

I'm also eying on the sleek LG grinder. The one thats thin and long.. Hopefully it would reach those tight spaces..

[JayL]

Given a chance I would want to try a Metabo 4 or 4 1/2 angle grinder and see for myself why these are so expensive and if it's worth paying their price.

[rosy]

I have accummalated a number of tools for my welding projects and can attest that angle grinders
are a must for these kind of metal project, I would use my grinders sparringly from 4" grinder up to the 9"grinder.

I think there is no need for one to be using the best angle grinder anybody can find unless it will be for heavy
industrial applications. Simply AVOID the fake ones being peddled around or the ones sold at the banketas
somewhere at raon. What if lets say you bought a famous known grider, may it be Makita, Bosch or Dewalt and
then uses it for your intended application and suddenly bogs down, what then and how would you feel not knowing
what you paid with your hard earned money is a lemon, well I guess this can also happen to not so branded
power tools.

My grinders are mostly BLACK & DECKER , just right for my DIY applications, and even bought a lotus brand
just to compare its motor quality with the B & Ds that I use and none has bogged down even ones. I would use them
heavily during metal projects, one for cutting, another two for grinding and another for wire brushing.

Lucky for me cause I was able to purchase a DEWALT 9" grinder for only 5K more than half less of the original
selling price of 12K. They were selling 2 units then and were giving it at a mark down price coz new batch
of stocks will be coming in.

[clayfigur]

I just bought a 710W KYK from binondo, It kinda powerful for the sleek design, and is backed up by a local warranty.. I like it cause it is easily gripped even if you only use one hand in grinding.. I also bought another 600w makita.. I really like light weighted grinder in fiberglass projects...

Please let us know how it holds up to the task. If possible post also some prices / pics so our other members wanting to go into metals can get an idea for their budgeting purposes.

what is now the best angle grinder on its class? :D

What size?

what is now the best angle grinder on its class? :D

Hi guys, a couple of weeks ago I purchased another angle grinder, t'was a 7" DEWALT angle grinder at a DIY store near us. I purchased it as a back-up for my other BLACK & DECKER 7" angle grinder. Now I'm using both on my current metal project and this DEWALT is so powerful and is lighter and is more compact in design.

I paid about php 6,999.75 for the unit plus free 2 pcs. 7" grinding disc. By the way I think DIY stores are on sale up to the end of this month, May 31. Maybe I'll be heading back soon to that store for anothe 4" Dewalt or a Makita or maybe a Bosch variable speed grinder before the sale ends.


Anyway in another thread I made a comparison of both 7" grinders, their features and specifications, it was not a review but merely back to back comparison since both units came from the same manufacturer, I think, the B & D for DIYs and the DEWALT for industrial applications.

Now with regards to the question what is the best angle grinder ? well I guess that will depend on the one using the grinder that will suit him best IMHO. Locally we have good different brands in the market to choose from, there's Makita, Dewalt, Bosch, Black & Decker and recently the Hitachi., did I miss a brand ?, they all offer great new features in their units. Oh yes of course there's the AEG and the Metabo brands.

Anyway here are pics of the DEWALT 7" angle grinder.

maybe i could share my experience with my angle grinder

i have a 4" Bosch single speed, i had it since 1998, it bogged down on me just last year and took it to a shop for repairs, the technician told me the armature got fried and it would cost me P1500 for a replacement. wow, thinking back , this grinder only cost me P2000 on sale back then

So i decided, maybe i should a new one instead. Impressed with Bosch quality, i got another but this time the 4" variable speed one. Upon use i was disappointed as the unit they gave me becomes too hot to handle in a few minutes. I compared the stickers/nameplate on my old Bosch and me new Bosch AG, my old one says it is Made in Malaysia and my new one is Made in PRC. The metal head on my old grinder case seems more sharply and cleanly cut/machined then the new one which shows some chipping at the edges.

went back to the store with my old grinder to show it to them, the stock they have are all Made in PRC and still becomes hot to handle upon testing in their store. Luckily i noticed the one on their display window is Made in Malaysia, like my old one! So that one i got. it worked splendid.

Here's a bonus:
they checked my old Bpsch grinder and found out it was just a spent up carbon brush, wow, haha
it was my old technician who sold me that carbon brush, and i never suspected of a spent carbon brush, it's just been barely two months since he put it there when it bogged down. i think he was just ripping me off then, trying to sell me his armature, pfft.

NOW I'VE GOT TWO !!!

[rosy]

@ xyname,

HE he he he , good for you bro now you have two grinder toys to play with, but reminder lang, usually an electric power tool like grinders or drills or chop saws or any other tool runned by electric have carbon brushes that should be checked ones in a while to see if it already needs to be replaced and by doing so will prolong the life of your tool.

CHEERS and stay safe when using your angle grinders.

[xyname]

thanks po, hihi

when i had only one grinder, i've been itching to buy one more
changing blades for cutting/grinding/sanding takes a bit of time from the limited time i have for DIYs

with what happened, it just gave me a kick in the butt to go buy another, hehe

where do you get the malaysian one?

[spyghost]

cr@p, went over to panda this afternoon and no more stock of gws8-100ce (both in araneta and binondo) :(

[owyn]

At work where grinders get used till they die, they've gone through at least 2 maktecs and 2 china makitas in the last 4 years. Both brands last about the same, the difference was in the noise and vibration that goes up into the hand. The current welder really has no finesse- he'd bear the grinder down into the workpiece (instead of letting the tool do the work) till the RPMs drop down. Hard on the tool and not that safe either (but i've stopped making these guys change, i've given them my own safety glasses and they'd remove it the minute i've turned my back. Great can-do, make-do attitude w/c is also the bad part.)

Been wanting this but can't justify since i rarely use grinders as a hobby. Makita's made in japan model:
http://mayonconstructionsupply.com/sites/default/files/imagecache/product_full/9500nb.png
http://mayonconstructionsupply.com/content/9500nb

Not the most powerful out there at 570watts, but the benefit is that the body is slimmer and nicer to hold. Have no experience with it, but i love my made-in-japan makita drill as others love their authentic japanese (2012nb) planers and routers (3612 series.)

It's 8K on malls but it's around 5K iirc at LYS.

Metabo - works best and sound better when under lots of grinding pressure. Cuts grinding time in half.

[timber715]

grinders are considered to be the most dangerous powertool. Bec. the blade is blunt it gets no respect but this pt has killed (yes, Killed!!!) the most number of people, so is safety a concern here?:agree: So what are you looking for? Do you want a safer tool with the same performance or just performance?:poke:
well Bosch has the feature called "kickback stop" for those who attended the last seminar eb this needs no explanation, but for those who did not make it... check the video kickback stop (http://www.youtube.com/watch?v=XeCWZiFew6A) it also shows the electronic protection the Bosch grinders offers...:dracula:

[timber715]

compared to what grinder brader? and are the variables the same, i.e. grinding discs and material being grinded?

[balarila]

Ditto to Timber's comment re the dangers of grinders.

I have a little B&D grinder which I occasionally use when I need to remove fast lots of wood or hard epoxy gunk. Even got into the habit of removing that "inconvenient" metal guard, using it without the other handle in a one-handed fashion, over-extending my arm into hard to reach places. More than once, the grinder just danced out of my hand.

Now, I always practice safety in my shop: gloves, thick clothing, knee-pads, steel-toed boots, eye protection, ear muffs, respirator. The works! But I never realized the danger of grinder misuse because, as Timber said, it has an innocent looking blunt disc, much less threatening than the sharp serations of a saw blade.

After attending the Bosch seminar, I have a lot more respect for this little "killer".

I like the Bosch kickback stop. I also like the restart protection. That shock-absorbing handle should also be great for long use.

[violaine]

@jay,

OT brader...

my 5 inch NOS metabo hasnt seen any action until last week when i paid a visit at toolsfromus and got a metabo made in germany 5inch cutting disc for 85pesos/pc...i think it is more economical to use the 5inch wheel than the 4inch counterpart..and saves you the hassle of changing wheel when its passed its capacity (usually just half of the disc is unusable and becomes a trash)...4inchers can be had from 45 pesos to 55 pesos a piece...with my 4 incher bosch, i am happy with a superslim johnbenzen cutting wheel for stainless steel at 45/p per piece...the 3M standard thickness cutting wheel is around 55-65pesos (mall price)..there is a Lotus wheel but its more than 4" diamater..perhaps 4.5" (eyeballed) and havent used it yet...which i got for 60pesos.

the antivibration handle isnt available but can be ordered (at toolsfromus)...i saw one metabo 5 incher sporting an antivibration handle fetching at 8K...do you think there is a way to DIY that kind of handle with local materials?

V

@timber,
but surely, that anti-kickback of Bosch is a sure safety winner!:punk:

Talking about ANGLE GRINDER safety use, I have here some safety tips for new owners or other former owners/users that have taken the tool for granted ( I mean its safety use ). I have posted these links with other safety tips on another thread, " Let's Talk about Angle Grinders " post or reply # 50.

Hope these links will help/remind us of the proper use of this tool, the blades or grinding discs we install or use may not be sharp but what makes it very dangerous is its spinning power that reaches up to 12000 RPM.


CHEERS and always STAY SAFE with power tools !!!!! :lolabove:

[JayL]

Angle grinders like most tools need some time to learn how to use well. If you are a newbie then I suggest you take it slowly in the beginning. Use the guard always and study how the different attachments ( grinding, cutting & flap discs , wire wheels, cup brushes ) behave. If the cord is tangled then stop and take time to untangle it. Position the guard accordingly too. The side handle will be a good way to control the grinder.

That said and after several metal wips I now like to ram the grinding disc into the metal as hard as the grinder can take it to finish the job quickly ... LOL

However for more safety purposes I find the paddle switch grinders to be a notch above. As soon as the paddle is released the grinder immediately begins to stop. This is good specially for out of position grinding like in overhead. There will be times when the WIP will be very heavy to move already and the operator has to position himself according to the WIP. Here the dangers start to multiply.

Ok, I needed one now so I settled with gws7-100 from panda. No need for more power bec its just for fiberglass shaping cutting and trimming... This little dude is noisy as ****! I still need to get discs for my application. Panda doesn't have the grits I need.

got a new grinder today... GWS 8-100 Z....... from Bosch of course:rockf:
and no its not yet available anywhere....:secret:

here is a video of the Kickback Stop (http://www.bosch-pt.com/videos-ocs/blue/GWS11_14/en/dsl.wmv)

[butch11a]

nice grinder, when will they be available locally? bosch also has the skinny 4" angle grinder, that one seems nice since its easier to handle specially if your wearing gloves, i have the bosch variable speed grinder too and 2 makita's with the switch on the side, a 9" bosch grinder and a ryobi professional grinder the small one with the metal housing, an old black and decker and several air angle grinders, among all of them, the ryobi runs the smoothest, the makita's are a bit noisy but the air angle grinders are the most durable....most pneumatic tools are, they just need cleaning and a few drops of oil once a day....

thet are already out for a while now. Just check the 5" grinders with the "Kickback stop" sticker on the grinder. the 4" grinders still do not have that feature...
