Irwin Unibit drill

For drilling wide holes in thin sheet metal I bought Irwin Unibit drill bit. It is self-starting drill.

For testing purposes I used steel sheet from ATX power supply box. Starting hole is a bit angular, next sizes are quite good. Only need to adjust the speed of the drill- to cut the steel, not grind.
