Milwaukee MX4 4-Cutter SDS Max Rotary Hammer Drill Bit 48-20-3988
ULTIMATE REINFORCEMENT DOMINANCE
In the high-stakes world of heavy civil infrastructure, you don't just drill holes; you battle thousands of yards of high-density aggregate and structural rebar. The Milwaukee MX4™ SDS Max 4-Cutter bit is forged to withstand the violent torque of high-output rotary hammers, utilizing a proprietary solid-head carbide that refuses to shatter when the environment turns brutal. When your production schedule depends on high-speed anchoring in bridge decks or foundation piers, this is the only bit that ensures you aren't constantly swapping out burnt consumables or stalling out on heavy reinforcement.
- / Solid-Head Carbide: Engineered for extreme longevity in reinforced concrete, preventing the head from shearing even when encountering heavy structural steel.
- / Rebar Guard Technology: Built-in mechanical protections minimize the risk of bit bind-up, protecting the operator and extending the service life of your high-torque rotary hammer.
- / High-Volume Variable Flutes: Optimized geometry facilitates rapid dust extraction, reducing friction-induced heat buildup and maximizing holes-per-charge on battery-powered systems.
- / Sharp Centering Tip: Enables immediate engagement on slick, high-PSI concrete surfaces for dead-nuts layout accuracy on critical anchor patterns.
- / ANSI Wear Mark Indicator: Provides clear visual confirmation of bit integrity, ensuring every hole drilled remains within engineering tolerances for safety-critical inspections.
TECHNICAL SPECIFICATIONS
Cutter Count: 4-Cutter Solid Carbide
