# 10502850
The Irwin Step Drill Bits are designed for precise drilling in thin materials and have a single flute for maximum drilling control into sheet metal.
Their unique flute design ensures perfect round holes in sheet metal.
A fluted shank also prevents the drill bit from slipping in the chuck; along with self centering point that will not walk and eliminates center punching.
