Milwaukee SHOCKWAVE™ Metal Drill Bits are impact rated with a titanium coating that dispenses heat. Its 135° tip angle reduces tip walking and allows for a precise start. The chip breaker tip splits up the size of the material from the cutting edge and helps cool down the material. The flute design allows for a faster material ejection and decreases heat build-up for more efficiency. Fitted with a 1/4in hex shank making it suitable for impact and drill drivers. Supplied in a compact, convenient storage case with the following sizes: 3 x 65mm, 3.5 x 69mm, 4 x 71.5mm, 4.5 x 76mm, 5 x 93mm, 6 x 105mm, 7 x 109mm, 8 x 111mm, 9 x 117mm and 10 x 120mm.
