Irwin Impact Masonry Bits 3/16-Inch X 4-Inch Size:3/16" x 4" shorter cutting lips reduce torque

shorter cutting lips reduce torque when drilling in high tensile strength materials

7"x 1/4" x 5/8-11"

More accurate holes at any angle

Shank mounted files and rasps are tough

Irwin Impact Masonry Bits 3/16-Inch X 4-Inch Size:3/16" x 4" shorter cutting lips reduce torqueInnovative pressed carbide tip with aggressive cutting angles for faster drilling and longer bit life One piece construction withstands higher torque loads than standard quick change bits Black oxide finish resists corrosion and increases life of bit 1 4" quick change shank is designed to work with impact drivers, and reduces slipping in standard drill chucks
