The IRWIN WeldTec 1/2-inch Auger Bit features a hard cutting edge that is welded to the base material for improved strength and durability. The welded cutting edge on each WeldTec auger drill bit provides an extended cutting life. Wide flutes and a 3/8-inch quick-change impact shank provide added versatility.
The Irwin Tools 3043005- 1/2" 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.
