Milwaukee SDS Plus Thin Wall Carbide Tipped Core Bit 4″

HIGH-EFFICIENCY MASONRY EXTRACTION

Engineered for the rigorous demands of multi-trade jobsites, the Milwaukee 48-20-5055 4-Inch SDS Plus Thin Wall Core Bit delivers a decisive advantage when boring through brick, block, and masonry. By utilizing a specialized thin-wall profile, this bit minimizes surface resistance, allowing your rotary hammers to maintain higher RPMs while drastically reducing the thermal load on the tool’s drivetrain. This is a critical component for professionals who prioritize fleet longevity and high-velocity throughput on large-scale mechanical and electrical installations.

• / OPTIMIZED PENETRATION: Thin-wall geometry removes less material, providing significantly faster drilling speeds in abrasive masonry units.
• / SUPERIOR ALIGNMENT: Integrated guide plate and centering pin prevent bit drift, ensuring dead-on accuracy for every through-hole penetration.
• / 4-INCH CAPACITY: Large-bore diameter is purpose-built for commercial conduit, drainage stacks, and HVAC ventilation ducting.
• / INDUSTRIAL COMPATIBILITY: Designed for maximum versatility across the standard SDS Plus rotary hammer platform.
