Milwaukee SDS Plus 4-Cutter MX4 1/4" x 4" x 6" Drill Bit 15-Pack 48-20-7931
REBAR-REINFORCED DRILLING SUPREMACY
When your crew is burning through standard bits on a high-density concrete pour, the overhead costs of downtime and bit replacement skyrocket. The Milwaukee MX4™ series is engineered to mitigate that loss, utilizing a solid head carbide design that maintains structural integrity even during direct rebar strikes. For fleet managers looking to maximize the duty cycle of their M18 FUEL rotary hammers, these bits offer a 20% efficiency gain in dust removal, directly translating to more holes per charge and significantly less thermal stress on your cordless equipment.
- / SOLID HEAD CARBIDE: Delivers up to 5X longer life in reinforced concrete, ensuring your project timeline stays on track despite hard aggregate.
- / 4-CUTTER ANTI-LOCK DESIGN: Specialized geometry prevents dangerous and time-wasting lock-ups in steel rebar, protecting both the operator and the hammer's clutch.
- / VARIABLE FLUTE GEOMETRY: Rapidly clears dust to reduce frictional heat, resulting in up to 20% more holes drilled per battery charge.
- / INTEGRATED WEAR MARKS: Visual indicators confirm the bit still meets ANSI B212.15 requirements for critical anchor fitment.
- / PRECISION CENTERING TIP: Engineered for exact spot drilling on metal decking and slick concrete surfaces without bit walk.
