ENGINEERED FOR REINFORCED CONCRETE: MAXIMUM DURABILITY IN REBAR STRIKES

When your workflow involves deep-hole drilling in high-PSI concrete, the mechanical integrity of your bit determines your uptime. The MX4™ 4-Cutter SDS MAX bit is engineered with a solid head carbide that eliminates the common failure points of traditional brazed-tip bits. By utilizing a 4-cutter geometry, this bit prevents the catastrophic lock-up often experienced when hitting rebar, protecting both the operator and the tool's internal clutch. The optimized flute design facilitates rapid dust evacuation, which significantly reduces thermal buildup and allows your rotary hammer to maintain higher RPMs, resulting in up to 15% more holes per charge on cordless platforms.

• / Solid Head Carbide construction provides up to 5x longer life in heavy rebar applications compared to standard 4-cutter bits.
• / Integrated Rebar Guards shield the carbide tip from high-impact damage during aggregate and reinforcement strikes.
• / Sharp Centering Tip ensures exact spot drilling, preventing bit walk on smooth concrete or metal decking surfaces.
• / Wear Mark Indicators provide a clear visual reference for ANSI B212.15 compliance, ensuring every hole meets anchor specification requirements.
