Many times I used a chisel to cut off a hard-to-reach piece of lumber, I was wishing I had an adequate blade for my 4.5" grinder, as I don't own an oscillating tool. Why is it hard to find? Is it because they would be dangerous?

The other big question is if your grinder accepts the flat type or the curved type – Steven Jan 3 '13 at 22:39

They are made, they look like mini chainsaws and are commonly used for carving bowls.

Lancelot and Discs

A common brand for these blades is Lancelot

You can also get smaller saw blades in the 4.5" form factor. I suggest you go to a saw store or woodworking shop. Here is a product on Amazon:

why would anyone call their product Bad Blade??? – amphibient Jan 4 '13 at 17:44
The "bad blade" looks like an amputation waiting to happen. It's a circular saw blade but spinning at 10,000 RPM and with none of the characteristics of a circular saw that help keep it safe (retractable guard, a shoe to keep the blade aligned vertically). You couldn't pay me enough to use one of these blades in a grinder. – Mike Powell Apr 16 '13 at 4:09

The primary reason is grinders typically spin at 10,000 rpm. Wood cutting saws typically spin in the 3500 to 4000 rpm. If you spun a typical circular saw blade at 10,000 rpm it would come apart. As @Matthew PK has shown they make wheels for working wood with a grinder but they are not the typical toothed blades.

RPM is a good point, but then again biscuit joiners spin at 10K RPM as well, and they've got a similarly sized blade. 7-14" blades have a much higher tip speed (proportional to radius), and therefore much higher internal forces at the same RPM. – Doresoom Jul 10 at 19:44

I got a wood blade to fit my angle grinder out of a old biscuit jointer My advice is be very careful ,It kicks back something terrible We call them widow makers here in Australia

That sounds horribly unsafe. Please tell me you at least use a guard with it! – Doresoom Jul 10 at 19:45

I have an old Makita mini grinder that my dad out fitted with a 5" wood cutting blade from a mini circular saw. Unfortunately it has no guard and no handle. We use it for hard to reach areas that a regular circ saw or reciprocating saw won't reach. But my dad and I have nick named it the "killer" because it is the scariest tool I've ever used. if you're making a deep cut in wood and it catches because you twisted the blade, it kicks out uncontrollably. I agree with the guy from Down Under, a mini grinder with a wood cutting blade is recipe for disaster. That's the most logical reason why they don't make a wood cutting blade for a mini grinder, due to the high speed of the blade.
