Product Description
Milwaukee SDS+ Bit 1/4 in. x 4 in. x 6 in.
Model Number: 48-20-7431
The Milwaukee 48-20-7431 is an SDS+ rotary hammer drill bit in 1/4 in. diameter with a 4 in. working length and 6 in. overall length — an individual unit of the standard compact 1/4 in. configuration for light-duty concrete anchor drilling, available as a single bit for contractors who need a specific replacement, are trialing the Milwaukee 44 Magnum series, or who use this size in low quantities. The 1/4 in. diameter is used for small concrete screw anchors, light-duty expansion fasteners, and specialty concrete drilling applications throughout commercial and residential construction. Milwaukee 44 Magnum SDS+ bits feature carbide vacuum-brazed to heat-treated steel shanks with dual cutting edges and optimized fluting for consistent concrete drilling from first use through the end of the bit's service life — the same manufacturing quality across individual units, 5-packs, and 25-packs ensures that a single bit purchased here delivers the same reliable performance as any bit from a bulk pack of the same specification.
The compact 6 in. overall length with 4 in. working depth is the right configuration for typical light-duty anchor embedment depths and ceiling penetrations where the required hole depth is within 4 in. and where the compact length provides the drilling access advantages of a shorter bit in overhead, near-obstruction, and confined-space drilling situations. The SDS+ shank engages all SDS+ rotary hammer chuck systems tool-free for fast bit installation and removal. For contractors who regularly install 1/4 in. anchors at production volume, the 25-pack format (48-20-7531) provides significantly better per-bit economics than individual unit purchasing — the individual unit here is the right format for occasional use and single-bit replacement applications.
See Milwaukee's complete 44 Magnum SDS+ catalog for all pack quantities and extended lengths at the 1/4 in. diameter.
