Deep and precise concrete drilling
- Robust Milwaukee four-cutter design: The symmetrical four-cutter geometry ensures you drill perfectly round holes in reinforced concrete for secure anchor fixings.
- Fast and efficient dust extraction: The high-volume four-flute channel clears dust rapidly, reducing friction so you maintain high drilling speeds.
- Accurate spot drilling control: The sharp centering tip prevents wandering so you start each hole with pinpoint accuracy on dense stone.
Drill through thick concrete walls with absolute power and precision using the Milwaukee SDS-Plus MX4 hammer drill bit in 20x1000 mm. Featuring a 940 mm working length and a solid 4-cutter carbide head, this bit powers through masonry and reinforced concrete in a single pass without jamming on rebar. The sharp centering tip prevents wandering for pinpoint starts, while the 4-flute spiral channel clears dust rapidly over long drilling depths to reduce friction. With its pgm certification, you are guaranteed perfectly round holes for approved structural anchor fastenings and conduit runs.
Product description
- The Milwaukee MX4 SDS-Plus drill bit is engineered for the toughest applications, featuring innovative fully welded solid carbide tip technology (up to Ø 20 mm) for maximum durability in rebar and unmatched drilling speed in concrete.
- 4-Cutter solid carbide tip: Enhanced geometry with a sharp centering tip, rebar guards, and new dust grooves delivers clean starts, precise holes, and maximum life when drilling through rebar - even under extreme jobsite conditions.
- Optimised flute design with reinforced core: A thicker core combined with alternating SPEED and HEAVY-DUTY spirals ensures fast debris removal, reduced friction, and superior stability in demanding applications.
- Convex shank for maximum energy transfer: The convex shank end optimises energy transfer from tool to tip, boosting impact force, drilling efficiency, and jobsite productivity.
- One-Piece slotted carbide tip for Ø >20 mm: For large-diameter concrete drilling, this design offers exceptional strength, extended bit life, and break resistance in heavy-duty use.
- PGM certified: Meets industry standards for precision and safety, making it the ideal choice for anchor setting.
- Made in Germany: Manufactured to the highest standards for uncompromising quality, reliability, and performance on every jobsite.
