UNRELENTING STRUCTURAL PENETRATION

When you're dealing with high-cycle production on a bridge deck or a deep-foundation civil site, you need a core bit that handles the raw torque of an SDS Max monster. The Milwaukee 48-20-5155 4-inch Thick Wall Core Bit is the heavyweight champion of concrete removal, designed specifically to withstand the violent impact energy of large-scale rotary hammers. By focusing the tool's energy on the kerf rather than the entire surface area, it chews through cured, high-PSI aggregate without taxing your powertrain. It's the difference between a clean, profitable pass and a burned-out motor when the deadline is looming on a heavy civil project.

• / INDUSTRIAL THICK-WALL FORGING: Engineered for maximum durability and heat dissipation when paired with high-output SDS Max or Spline drive hammers.
• / HIGH-VELOCITY KERF CUTTING: Increases drilling speed and reduces mechanical strain by only removing the outer ring of material.
• / ZERO-WALK PRECISION: Utilizing the included centering pin and guide plate to ensure dead-accurate hole placement even on vertical structural faces.
• / MODULAR ADAPTABILITY: Fully compatible with 7-1/2" extensions and various shank adapters for deep-wall penetration and cross-platform utility.
