  • Additional Information
    • The CONFAST® Carbide Spline Bit fits into the large construction hammer drills that exclusively use the spline drive connection system.

      • The splines on the shank of the CONFAST® Carbide Spline Bit slip into the corresponding spline of the chuck, providing positive torque and hammering characteristics.
      • The description of the CONFAST® Carbide Spline Bit is made up of two numbers: the first number is the bit diameter, and the second number is the overall length.
      • The usable length of all CONFAST® Carbide Spline Bit is 6" shorter than the overall length; the rest of the length refers the shank that connects to the hammer drill.
      • Hammer drills utilizing the spline shank are large in size, weigh more than 14 lbs., and are mostly used for drilling larger holes or large quantity of holes.
