BENCHMARK 1/4" Step Drill Bit Set - 3 Piece

This Benchmark 3 Piece Step Drill Set can be used for drilling or enlarging an existing hole in thin materials such as sheet metal. The split point tip ensures the bit will not drift when starting. When reaching the desired hole size, the chamfer edge (the transition of two steps) is used to make a smooth and burr-free surface.

• Titanium-nitrate coating creates less friction and runs cooler, while extending blade life
