Milwaukee SDS-Plus RX4 Concrete Drill Bit 8x115 mm - Ref. 4932352021

Advanced Carbide Technology

These concrete drill bits feature ultra-resistant carbide cutting edges that ensure fast penetration and remarkable longevity. The optimal 4×90° geometry of the four symmetrical edges ensures clean and precise circular drilling, even in the most demanding reinforced concrete, while effectively preventing tool jamming.

Reinforced Design

The large diameter body offers superior bending resistance and optimal vibration absorption. The symmetrical quadruple spiral allows efficient dust evacuation and ensures even tool wear. Reinforced carbide welding equips diameters 5 to 10 mm for increased penetration speed, while diameters larger than Ø 18 mm benefit from a 3-piece carbide head.

Optimized Performance

The revolutionary variable geometry flute adopts a thinner section at the tip for rapid debris evacuation, reducing friction and significantly increasing drilling speed. The thickened base ensures maximum stability and increased break resistance. This design allows for up to 20% additional drilling per battery charge compared to classic 4-cutting edge drill bits and the previous generation on concrete.
