Product Description
Milwaukee SDS+ Bit 7/32 in. x 12 in. x 14 in.
Model Number: 48-20-7425
The Milwaukee 48-20-7425 is an SDS+ rotary hammer drill bit in 7/32 in. diameter with a 12 in. working length and 14 in. overall length — a deep-reach configuration of the 7/32 in. SDS+ bit for small-diameter anchor drilling in thick concrete sections, through-block wall penetrations at this diameter, and dowel hole installations requiring embedment depths that exceed what standard-length bits can achieve. The 7/32 in. diameter is used for light-duty concrete screw anchors, small expansion anchor pilot holes, conduit hanger screw anchors, and other small-fastener concrete installations throughout commercial construction. At 14 in. overall length, this bit accesses drilling locations through thick CMU block walls, elevated concrete slabs from below, and thick concrete structural sections where anchor embedment specifications require hole depths significantly greater than what the 6 in. standard-length version can drill. Milwaukee SDS+ bits feature carbide tips vacuum-brazed to heat-treated steel shanks with dual cutting edges and the optimized helical flute geometry that maintains efficient debris evacuation throughout the full working depth of extended-length bits.
Extended-length SDS+ bits at small diameters represent a particularly demanding application for flute engineering — the 7/32 in. diameter bit body has limited cross-sectional area for flute volume, making each cubic centimeter of flute space critical for maintaining adequate concrete dust transport capacity over the 12 in. working depth. Milwaukee's flute geometry for this bit is specifically engineered to maintain effective concrete debris evacuation at this diameter and working depth combination, preventing the hole packing and bit binding that slows penetration rate and causes bit breakage with inadequate flute designs at extended lengths. The SDS+ shank provides tool-free engagement in all SDS+ rotary hammer chucks for quick bit setup and changes during production anchor drilling operations.
For high-volume installations, this size is available in 25-pack bulk packaging to reduce per-bit cost on projects requiring large quantities of 7/32 in. anchors in thick concrete sections.
