Milwaukee 5.5mm SDS+ MX4 Masonry Bit 4-Cut Carbide Tip

These MX4 SDS-Plus drill bits are designed to handle the toughest applications. Unlike standard SDS bits, they feature a fully welded solid carbide tip, which allows the drill to cut cleanly through rebar embedded within concrete while delivering up to 4x the lifespan of competing products.

A cross-designed tip delivers more cutting performance and allows the drill to stay true and straight when starting off, giving cleaner holes when compared to standard SDS bits. A specially designed fluting extracts dust with greater efficiency, speeding up drilling significantly. 

When you need a drill bit you can depend on to get the job done, you should reach for the Milwaukee MX4 SDS series. It is available in diameters from 5mm to 32mm and in a range of lengths.  

• The Milwaukee MX4 SDS-Plus drill bit is engineered for the toughest applications, featuring innovative fully welded solid carbide tip technology (up to ⌀ 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 ⌀ > 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.
