Drill with wheel head instead of (dremel) rotary tool?

(new member)

quick question:
Instead of buying a dremel rotary tool, couldn't I just buy a drill head that mimics the wheel-cutter attachment.... that you would normally use on a dremel?

Nope, not with any real effectiveness. The not-so-secret advantage of a rotary tool is speed. High speed, in the vicinity of 25,000 to 35,000 RPMS speed. A drill may get you around 3,000 or so RPMs, not nearly enough to take advantage of a rotary tool's various bits and cutters. And, as an afterthought, the rotary tool is much more nimble and precise because of its smaller size.

I use a foot peddle speed control at work and NEVER use any bit all out. Even the grinding disks are at most half speed-too much heat among other things.

If you are using a full size grinding machine with industrial loads and hold-downs, THEN you might want 25K (or more accurately, high surface feet per second ).

+1. A drill doesn't rotate nearly fast enough, nor is it easy to hold for precision work.

Another problem with using a drill is that the drill's mechanism probably isn't designed for a lateral load. It's meant to go straight in and straight out. A Dremel or other rotary tool is designed to cut sideways.

Welcome!

You can use dremel bits on a normal drill, but generally a normal drill only does 1-2k rpm. A dremel does 4-8k rpm. Some bits rely on the high speed to counteract the low torque of the tool. Depends on the desired job and the tool in question. Cutter wheels might work, but will be VERY slow in a drill.
