Milwaukee® SDS Plus MX4 4-Cut drill bits are the professional solution to tackle reinforced concrete drilling with its target tip technology, sharper angled tip for exact spot drilling and a solid 4-cut Carbide head (on Ø5-10mm) to deliver speed optimisation, longer life and maximum durability in rebar. The high volume four flute design ensures enhanced dust extraction that results in faster drilling and less wear. The variable flute design gets thicker towards the core to increase flute durability. Packaged with both flat and pointed SDS Chisels perfect for versatile demolition applications. The 140mm Flat Chisel is ideal for scraping, scaling or smoothing surfaces, often used on tiles, thin layers of concrete, render, plaster and mortar. The 140mm bullpoint chisel focuses on impact, shattering energy from one point. Often used for starting holes, breaking up concrete, stone or masonary.
