Milwaukee® 48-20-4405 4-Cutter Rotary Hammer Drill, 1-1/4 in Dia x 36 in L, 31 in Cutting, 3/4 in Spline Shank, Carbide

Milwaukee® Spline 4-Cutter Rotary Hammer Drill bits feature a 4-Cutter 4x90 deg tip geometry to avoid lock up in rebar, patented rebar chamfers for increased durability and a high volume flute for fast debris removal. Used for drilling holes in brick, block, concrete and reinforced 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
• Four cutter bits have a series of 13 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 four cutting edges which pulverize the concrete as the bit turns and pounds the work surface
