Milwaukee SDS Plus Thin Wall Carbide Tipped Core Bit 3-1/2″

ACCELERATED LARGE-BORE MASONRY EXTRACTION

The Milwaukee 48-20-5050 is a strategic asset for service operations requiring consistent, large-diameter penetrations in abrasive masonry substrates. By utilizing a sophisticated thin-wall geometry, this core bit prioritizes torque conservation and speed, cutting only the outer kerf to bypass the high resistance found in standard solid-head bits. For any crew managing a fleet of SDS Plus rotary hammers, this design translates to significantly reduced mechanical wear, faster cycle times, and lower energy consumption per hole on both corded and cordless platforms.

• / OPTIMIZED KERF DESIGN: Minimizes material removal to maximize drilling velocity and battery runtime on cordless tools.
• / PRECISION ALIGNMENT: Includes a guide plate and centering pin to eliminate bit walk and ensure layout accuracy during the initial engagement.
• / REINFORCED CORE BODY: Hardened steel construction resists deformation under high-impact loads in cured concrete and brick.
• / MODULAR INTERFACE: Compatible with 7-1/2 inch extensions and standard SDS Plus adapters for versatile jobsite application.
• / RAPID DEBRIS CLEARANCE: Thin wall profile allows for efficient dust evacuation, preventing heat buildup and premature bit failure.
