Irwin Tools 3043007 5/8" x 17" WeldTec Ship Auger
The Irwin Tools 3043007- 5/8" x 17" WeldTec Ship Auger is made stronger and last longer because a harder cutting edge is welded to the base material.  The result is 2x longer nail cutting life versus traditional Irwin Speedbor Ship Auger Bits.  The superior performance and durability of WeldTec is only available from Irwin.
