The Milwaukee MX4 SDS+ Drill Bits are an intricately designed accessory that delivers perfect round holes for optimal anchor fitting. The bits, with sharp angled tip design for easy spot drilling as well as increased performance on rebar, have a symmetrical 4 cutter geometry. The four flute geometry design ensures a greater level of dust and debris removal which, in turn, prevents any blockage when drilling. The centring tip allows for easy spot drilling with pinpoint accuracy. The PGM rated bits include 4 breaker points that pulverize material mor effectively which increases drilling time while the enhanced rebar guards offer an improved resistance when working on it. The 5-10mm bits are made from one piece solid welded carbide tip while the 12-32mm have a one piece slotted carbide tip. The addition of the carbide tip increases the lifetime of each one.
