JW, I have to disagree. I have the Milwakee (sp?) version of the
Rotozip, and when cutting abrasive materials like sheetrock and
particle board, you go through a HSS cutter every few feet of cut. I
was cutting around ther permiter of my kitchen ceiling to replace it,
and went through 2 HSS cutters in less than 4-ft of cut.

A single carbide cutter did the rest of the job -- in total about 60-ft
of cutting 1/2" sheetrock.

If you find yourself snapping off the carbide bits, the problem is not
the bits but the fact that you don't know how to use your Zip saw. You
have to keep the guide of the Rotozip flush with the surface you are
cutting at all times. If you do, it's practically impossible to break
carbide cutting tools unless you try to push the tool faster than it
can cut.

My opinion is that HSS cutters on Zip saws are all but worthless.
Carbide is the only way to go.
