Used this to cut countersink holes in steel plate for tapered-head Allen bolts. I was spinning the bit at a low speed, using copious amounts of cutting lubricant, and not applying excessive pressure, but by the 3rd hole I got to, the bit started cutting slower and slower. Not impressed with it's ability to stay sharp.
