Designed with a double-ground, extra-deep flute, the 1/8 in. x 1-1/2 in. x 3 in. Rotary Percussion Drill Bit removes dust fast for increased drilling speed. Manufactured with a chrome-vanadium spring steel shaft, it’s durable for a longer bit life. And the copper braze material gives this bit high heat resistance for reduced tip loss. This bit fits all hammer drills with a 3-jaw or Jacobs chuck.
