Product Description
Milwaukee SDS+ Bit 5/32 in. x 4 in. x 6 in.
Model Number: 48-20-7401
The Milwaukee 48-20-7401 is an SDS+ rotary hammer drill bit in 5/32 in. diameter with a 4 in. working length and 6 in. overall length — a small-diameter, compact SDS+ bit designed for anchor pilot holes, screw anchor installations, and light-duty concrete and masonry drilling in applications where a compact, maneuverable bit is required. Milwaukee SDS+ concrete drill bits feature carbide tips vacuum-brazed to heat-treated steel shanks — the vacuum brazing process creates a metallurgical bond between the carbide cutting insert and the steel shank body that withstands the combined rotational and hammering forces of SDS+ rotary hammer drilling without tip separation or loss under sustained use. The sharpened carbide geometry creates two distinct cutting edges that score and progressively crush concrete on each rotation while the bit advances into the material.
The optimized flute design continuously channels pulverized concrete dust and fragments out of the hole during drilling, preventing debris buildup in the hole that would cause binding, overheating, and reduced penetration rate. The SDS+ shank engages any SDS+ rotary hammer with a simple push-and-twist tool-free motion, locking securely for drilling and releasing just as easily for fast bit changes during production drilling operations. At 5/32 in. diameter and 6 in. overall length, this is the compact bit for tight-clearance overhead and horizontal drilling near walls and obstructions where longer bits cannot maneuver, and for setting small-diameter concrete screw anchors in floors, walls, and ceilings where minimal hole size is specified.
Individual packaging provides the most economical purchasing option for contractors who need a specific diameter for a single application. High-volume users and crews who install large quantities of same-size anchors should consider the 25-pack bulk packaging available for this size.
