Product Description
Milwaukee SDS+ Bit 5/16 in. x 10 in. x 12 in.
Model Number: 48-20-7444
The Milwaukee 48-20-7444 is an SDS+ rotary hammer drill bit in 5/16 in. diameter with a 10 in. working length and 12 in. overall length — a medium small-diameter extended-length bit for concrete screw anchor pilot holes, small-diameter through-wall penetrations, and deep embedment anchor installations at the 5/16 in. specification where the extended length is required to reach drilling depths beyond what standard-length bits provide. The 5/16 in. diameter is the correct pilot hole specification for a range of concrete screw fasteners, small expansion anchors, and specialty concrete fastening systems used in light structural connections, conduit support, equipment mounting, and general construction concrete fastening throughout commercial and residential projects. Milwaukee SDS+ bits feature carbide vacuum-brazed to heat-treated steel shanks with dual cutting edges and optimized helical flute geometry for consistent, efficient concrete drilling performance from first use through the bit's service life.
The 12 in. overall length and 10 in. working depth extend the application range of the 5/16 in. bit to include through-wall penetrations in standard CMU block construction, deep slab anchor installations where longer concrete screw embedment depths are specified for pull-out load rating requirements, and drilling from positions where obstacles or structural elements prevent the drill from being positioned close to the wall surface — all applications where the 6 in. standard-length bit cannot reach the required hole depth. At this length, Milwaukee's optimized flute geometry maintains efficient concrete debris evacuation through the full 10 in. working depth, preventing hole choking and bit binding that would require frequent depth-clearing stops during production drilling. The SDS+ shank provides tool-free engagement in all SDS+ rotary hammers for fast bit changes.
For high-volume anchor installation at this diameter, this size is available in 25-pack bulk format — see Milwaukee's complete SDS+ bit lineup for all lengths and bulk quantities available at the 5/16 in. diameter.
