This Milwaukee SDS-Max MX4 drill bit rises to the challenge on any site. A centering point with 130° point angle delivers easy spot drilling with pinpoint precision while ensuring optimum guidance.
The large carbide tip with patented rebar chamfers reduces vibration and increases drilling performance when hitting reinforced steel – the 4 x 90° symmetry of the tip also helps to reduce the risk of jamming up.
A big, robust secondary cutter with a dynamic, curved cutting edge supports the primary cutter for faster drilling, while shorter spiral windings ensure the faster transport of dust from the head to the flute – reducing wear and heat build-up at the tip for a longer life.

• 520mm total length – maximum working length of 400mm
• 20mm diameter – large carbide tip with rebar chamfers
• 4 x 90° tip symmetry – reduces the risk of jamming up
• Centering point – 130° point angle for precise spot drilling
• Low vibration drilling – less stress for user and machine
• Shorter spiral windings – less wear and heat build-up
• Reinforced flute geometry – better transfer of hammer energy
• Special surface treatment – increases wear resistance
