Milwaukee 4" x 11-3/8" SDS-MAX One-Piece Core Bit 48-20-5420

MASSIVE AGGREGATE PENETRATION

When you're staring down high-PSI reinforced concrete on a heavy civil site, you don't have time for multi-piece adapters that bleed impact energy. This one-piece Milwaukee carbide-tipped core bit is engineered for the sheer survival required in extreme demolition and utility environments. Designed to maximize the energy transfer from your SDS-MAX hammer directly to the substrate, it turns the hardest masonry into dust with industrial-grade efficiency.

• / ASYMMETRICAL TOOTH GEOMETRY: Alternating tooth patterns shatter aggregate and pulverize material faster than standard uniform bits.
• / THICK-WALL CORE BODY: Engineered to withstand the relentless pounding of high-joule rotary hammers without structural fatigue.
• / EXTERNAL FLUTED DESIGN: Optimized channels minimize friction loss and rapidly eject debris to prevent binding in shallow-depth drilling.
• / ONE-PIECE ENERGY TRANSFER: Provides a rigid, direct connection that ensures every ounce of hammer power reaches the carbide tips.
