Best Grinding Wheels

[acsuppa]

Hi guys, I'm looking for a good grinding wheel for my new 4 1/2" Makita Grinder. It came with some 26 grit ones which I really hate. I was wondering if a 60 or 80 grit would give me better results grinding welds. Also, my grinder came with type 27 wheels. Should I stick with that style or try a type 29? Thanks.

All depends on what you are needing to use it for.......I personaly like flap disk in the 29 style........some times you can find good deals on ebay for boxs of 25 and 50.

Thanks for the reply Mike. I basically will use it to grind welds and to do a "quick" clean of metal before welding. I've been reading a lot about the Flap Disks. I want to give them a shot. What would be the best grit to use for grinding welds? Also, will it be ok to use the type 29 with my Makita Angle Grinder? Thanks.

Not sure about all but I pick up the cheap ones from NT and the 36 grit ones last about 2 revolutions.......I like the 60 and 80's best as you can control the amount of material removed by how much pressure you use.I just picked up a couple from bullet industries and they seem to be the best balance of price and quality.......

Thanks for the reply Mike. I cheched out the bullet industries wheels that I believe you netioned in one of your other posts and they look good. The price is great. I was thinking about ordering some. I still can't seem to find out if I can use a different "type" of grinding wheel on my Makita. Thanks again for the advice.

you should be able to use any 4 1/2" disc.

Norton makes a really good one called AVOS. I like them in 36 grit.

I would indeed use a flap wheel to do surface prep for welding. I use a 40 grit on mine and it works wonders. There more expensive than regular disks, but they perform much better. I dont know the thickness of metal u are welding, but i know for thinner material, they work great. Even on thicker material. I would aslo use a Norton or Metabo type disk. Metabo is goin to be harder to find, but there hard to beat. Norton is probably ur best bet.

Thanks guys. The Norton ones seem to be real popular.

No problem. Yes the Norton ones are a popualr brand, but there worth the money. Good luck welding.
