Milwaukee Tool 48-20-5306 Sds-max Drill Bit 1-3/4 in

Product Description

The MILWAUKEE TOOL 48-20-5306 is a carbide-tipped SDS-Max rotary hammer drill bit built for heavy-duty concrete and masonry boring. The bit measures 1-3/4 inches in diameter with a 22-inch overall length, giving contractors and masons the reach needed for deep anchor, sleeve, and through-bolt applications. The SDS-Max shank locks into compatible rotary hammers without additional chucks or adapters. The chisel-cutting geometry combined with a carbide-tipped construction handles the impact loads of rotary hammer action while maintaining edge retention through abrasive concrete, block, and stone substrates. This bit is a single-piece unit weighing 5 pounds.

The 48-20-5306 is suited for commercial and industrial applications where large-diameter holes are required in concrete, reinforced masonry, or similar hard substrates. Typical uses include setting large-diameter wedge anchors, sleeve anchors, and through-bolts in structural concrete, as well as core layout work in block walls. The SDS-Max shank format is standard on larger-class rotary hammers commonly used by commercial concrete and masonry tradespeople on job sites requiring high-torque, high-impact drilling.

Compatibility

Designed for use with SDS-Max rotary hammers that accept the SDS-Max shank format. Verify your rotary hammer accepts the SDS-Max shank type before installation.

Installation Notes

Installation should be performed by a qualified mason, concrete contractor, or tradesperson familiar with rotary hammer operation. Ensure the rotary hammer is powered off and unplugged before inserting or removing the bit. Wear appropriate PPE including eye protection and hearing protection during operation. Follow applicable OSHA and job-site safety requirements for concrete drilling and anchor installation.
