Milwaukee® 48-20-4151 2-Cutter Rotary Hammer Drill, 1-1/2 in Dia x 22 in L, 16 in Cutting, 3/4 in Spline Shank, Carbide

Milwaukee® Spline 2-Cutter Rotary Hammer drill bits are used for drilling intro brick, block and concrete.

• Brazing formula optimizes drilling for up to 20% longer life
• Unique flute geometry provides efficient dust removal
• Centering point and 4-cutter design provide accurate and precise round holes
• Two cutter spline bits have a series of 12 spline that slide into an equal but opposite set of spline in the drive system of the spline drive hammer
• This positive engagement of spline to spline allows maximum transmission of energy from the hammer to the bit
• Superior quality carbide nibs are vacuum brazed to a heat treated steel body resulting in two cutting edges which pulverize the concrete as the bit turns and pounds the work surface
• 16 in useable length
