Milwaukee 1/2 in. Chuck Service Kit
Model Number: 14-46-9755
The Milwaukee 14-46-9755 1/2 in. Chuck Service Kit is a genuine OEM replacement service kit used across multiple Milwaukee cordless drill and hammer drill platforms, providing the complete 1/2 in. keyless chuck assembly with all associated retention components required for a complete chuck replacement. Milwaukee documents this part at Figure 64 on service parts bulletins 54-06-2995 and 54-24-2995, which cover related Milwaukee cordless drill/hammer drill platforms that share the same chuck assembly across different gearbox and electronic assembly configurations. The 1/2 in. chuck is the operator-facing tool interface that grips drill bits, hole saws, screwdriver bits, and other 1/2 in. or smaller shank accessories, converting the rotational output of the drill's gearbox into the fastener driving or hole-making action the tool delivers. On modern Milwaukee cordless drills and hammer drills, the keyless chuck design allows single-handed bit changes without the need for a chuck key, which is a productivity feature that separates professional cordless drills from older keyed-chuck designs.
A worn, damaged, or slipping chuck is one of the most common failure modes on a heavy-use cordless drill, since the chuck is exposed to constant torque loading, temperature cycling from motor heat, and the abrasive dust and debris that accumulate during drilling operations. Symptoms of a failing chuck include bits slipping under torque load, difficulty tightening bits securely against the fastener, difficulty releasing bits after use, visible damage or wear to the jaw teeth, or the chuck no longer holding runout tolerance for accurate drilling. Replacing the chuck with this OEM service kit restores correct bit retention, full torque transmission from the gearbox to the drill bit, and the runout accuracy the drill was engineered to deliver. Because Milwaukee Tool specifies replacement parts by both catalog number and serial number, always verify your tool's serial number against the official Milwaukee service parts diagram before ordering, since the 14-46-9755 fits multiple Milwaukee cordless drill platforms across two different service bulletins with different companion internal components. The companion service parts on the same bulletins (gearbox service assemblies, electronic service assemblies, belt clip service kit, and housing service assembly) vary by specific tool model - the gearbox and electronic assemblies specifically differ between bulletin 54-06-2995 and 54-24-2995. Order companion service parts by your specific tool's serial number rather than by assumption. Verify by serial number using Milwaukee's online parts lookup before ordering to confirm correct fitment.
