For those who use a handheld grinder for blades.What type of wheel do you use. I used a friends who a special type of wheel for i think for aluminum that took to the blade real good without using much pressure.

I forgot what type it was, any help?

most wheels for grinding aluminum are made with sillicon carbide. Since aluminum is a soft metal it clogs harsher grit wheels in a flash. For my blades and most all my metal grinding i use zirconium flapwheels by norton. http://blueridge.dreamscape.com/bysubcategory.asp?category=Abrasives&supercategory=Discs&subcategory=Norton+Flap+Discs++%2D+Type+27+Raised+Hub&type=False&specs=True http://blueridge.dreamscape.com/abrasives.asp

I'm going to use an angle grinder on my blades this year. The suggestion I read was to use a carborundum-coated/fabric backed disc on the grinder. Supposed to do the job quickly and easily.

I used a dremel too for a while to grind my blades. I now have a cheapy bench grinder from costco that does the job very quick.

it's only about $45.00 from costco to get a bench grinder and if all your doing is grinding blades it should serve you well for a while. it really cuts down on the sharpening time if you have multipule blades.

You chould balance you blades for your bearings sake.

Don't round off the tip of the blade with a grinder. If the square shape of the ends of the blades get rounded off , you will start to see uncut strips of grass, because the blade circles won't quit overlap anymore.

I use a 4.5" angle grinder too. the layered sanding discs work great for me. make a nice clean edge. iv'e tried a bench grinder and hated it, and yeah it's easy to start rounding the end with one. Iv'e even tried a Lesco blade grinder and I don't know if they are just junk or what but no matter what I did to adjust it it sharpened terrible. So i stick with what works, the 4.5" angle grinder with the layered disc.

The fastest way is with a 4" angle grinder with a 50 grit sanding wheel backed up with a cut off wheel. I use the cut off wheel as a backing because the standard rubber wheel they provide can get chewed up if you slip off the edge. I have done thousands of blades....and balancing don't seem to be necessary. I have never had to replace a bearing in spindle ...25 years and many mowers.

I agree with Viper, though I use a lot of different brands (based on price.) The flap disk canít be beat if youíre going to use an angle grinder.
