product works great, lasts long with proper use (50-100rpm) i've drilled a dozen holes in 1 1/4 sheet metal with no problem, just slow and slow lots of lubrication .

I used this tool to drill a hole in my garage wall to run some wires for a security camera and it used to go through the wall, I could say impressive! Very sharp, no drift, did exactly what I expected.
