Product Description
Milwaukee SDS+ Bit 3/8 in. x 8 in. x 10 in.
Model Number: 48-20-7453
The Milwaukee 48-20-7453 is an SDS+ rotary hammer drill bit in 3/8 in. diameter with an 8 in. working length and 10 in. overall length — an extended-reach configuration at the most heavily used commercial anchor diameter, providing additional working depth versus the standard 6 in. and compact configurations for through-wall CMU penetrations and deeper anchor embedments. The 10 in. overall length enables through-wall drilling in standard 8 in. CMU block with light finish material, longer concrete screw anchor pilot holes where pull-out load specifications require greater embedment, and drilling positions where the hammer must be held back from the drilling face. Milwaukee 44 Magnum SDS+ bits feature carbide vacuum-brazed to heat-treated steel shanks with optimized fluting for consistent debris evacuation through the 8 in. working depth at the 3/8 in. bore.
The 3/8 in. diameter is the most commonly drilled anchor size in commercial construction — covering the full range of light-to-medium structural anchor systems across conduit support, equipment mounting, and general structural fastening. At the 10 in. overall length, this configuration handles the majority of through-wall CMU applications and provides adequate depth for the longer embedment specifications frequently encountered in commercial anchor engineering drawings without the extreme length of the 18 in. and 24 in. extended configurations. The SDS+ shank provides tool-free engagement in all SDS+ rotary hammers for fast bit changes during production anchor installation operations. Available in bulk 25-pack format for high-volume production purchasing at reduced per-bit cost.
See Milwaukee's complete 44 Magnum SDS+ catalog for all available 3/8 in. configurations and pack quantities from individual through 25-pack.
