Can you cut hardwood with a diamond blade on an angle grinder?

Question

Will the blade get damaged, stuck? Is it dangerous? What happens? Or is it no problem?

Answer 1

If you try to cut hardwood with a diamond blade, youre going to smoke it. The blade will bog down, and get very hot.

For hardwoods you need an aggressive hook/angle to the tooth, for rapid removal of the sawdust. It is also important to (if cutting very much hardwood) either use a coated blade to reduce resin buildup, or use a special spray on, to help keep them clean. (Drycote, and Topcote are excellent products)

If you are wanting to cut hardwood to widths, I strongly recommend a good table saw, with about a 40 to 60 tooth blade. (40 tooth is a good overall shop blade, the 60 tooth will give a slower, but cleaner finish cut)

If you need to cut it to length, then a miter saw comes in handy.

Either of these tools can be rented, or you might check with a local cabinet supplier about running your pieces.

Answer 2

The Wrangler offers some valid points.

First of all the "SET" of any saw blade; combined with the number of TEETH, determines not only the smoothness of the cut; but the ease of it as well.

Beyond that; with an angle grinder it's the OPERATOR who isn't at all like the stability of a fixed blade on a table saw, for ripping; a chop saw for cross cuts; or even a "Skill Saw" for slightly less problems than the Diag. Grinder.

The example is simple. As a human; perhaps prone to angling your hands/ arms/ body/ to something different than a perpendicular cut; certainly you CAN get through the task; but will it be satisfactory? It's similar to thinking that drilling a hole in stock, a human can always keep the bit plumb and/or perpendicular.

Will the blade get damaged? More likely your stock will be possibly damaged.

Stuck? Possibly, but there again in may be in the various movements you make, and the fact that the Diamond Wheel is not strictly a BLADE.

Dangerous? Possibly; in as much as the Diag grinder might bind and kick back at you; perhaps not causing you injury, but I've experienced them tearing up pieces of tile in a backlash.

Answer 3

All of the above. Use the right tool for the job. Lots of us can rig something up that will work in a pinch but there are limits and the results are usually less than satisfactory compared to those you get doing it the right way with the right tool.

Answer 4

placed the grinder with grinding disc in the vise. placed wrench on nut and place so wrench is horizontal. Hit the tip of the wrench with a hammer utilising a rapid stable blow to the tip of the wrench. Nut turns counter clockwise to get rid of.

Answer 5

NO.
