Milwaukee 1-1/2" x 22" SDS Max Tunnel Bit 48-20-5302

DOMINATE DEEP STRUCTURAL PENETRATIONS

When you're punching through thick-slab concrete or reinforced foundations, you can't afford a bit that binds or fails at the first sign of rebar. This 1-1/2" x 22" SDS Max Tunnel Bit is engineered for the heavy civil sector, where deep-hole drilling requires consistent speed and structural integrity. Unlike standard core bits that require constant clearing of the core, the high-volume sloped flutes on this one-piece bit keep dust moving out of the hole continuously, preventing heat buildup and friction. The 3-cutter geometry and carbide centering tip ensure your start is dead-on, even when the surface is uneven, while the rebar chamfers allow you to shear through steel without sacrificing the bit's life or causing tooth fracture.

• / 3-Cutter Carbide Centering Tip provides pinpoint accuracy and aggressive grinding through high-PSI concrete and rebar.
• / Rebar Chamfers protect the carbide teeth from fracturing when encountering embedded structural steel in heavy-duty applications.
• / High-Volume Sloped Flutes ensure rapid dust evacuation, significantly reducing friction and preventing the bit from seizing in deep-bore holes.
• / 22-Inch One-Piece Construction eliminates the need for extensions and the downtime associated with clearing cores in deep penetrations.
