Milwaukee 2-1/8" x 22" SDS Max Tunnel Bit 48-20-5312

UNSTOPPABLE DEEP-CORE AGGREGATE DESTRUCTION

When your project demands a 2-inch corridor through a reinforced bridge abutment or high-PSI structural concrete, this Milwaukee SDS Max Tunnel Bit provides the raw clearing power and survival capacity required on the most brutal civil sites. Forget the downtime of clearing cores or the frustration of snapped teeth; this bit is engineered to stay in the hole until the job is done, utilizing specialized carbide geometry that treats rebar like a mere suggestion rather than an obstacle.

• / Robust 3-Cutter Head / Destroys large-scale aggregate with integrated concrete breakers for faster penetration speeds in high-impact applications.
• / Carbide Rebar Chamfers / Engineered to shear through heavy-duty steel reinforcement without catastrophic tooth failure, maintaining bit integrity.
• / 22-Inch Continuous Shaft / Optimized for deep-bore tunnel drilling, eliminating the need to stop for core extraction or frequent bit extensions.
• / High-Volume Sloped Flutes / Rapidly evacuates massive quantities of dust and debris to prevent bit binding and thermal overload during deep vertical or horizontal bores.
