Milwaukee Chuck Sleeve Service Assembly
Model Number: 14-46-7275
The Milwaukee 14-46-7275 is a genuine OEM Chuck Sleeve Service Assembly for the 2908-20 M18 FUEL 5/8 in. SDS Plus Rotary Hammer. On an SDS Plus rotary hammer, the chuck sleeve is the spring-loaded collar at the front tool holder that the operator pulls back to insert or release a bit. Inside that sleeve are the locking elements that engage the grooves in an SDS Plus bit shank, and the SDS Plus system is what allows the bit to slide back and forth axially so the hammer mechanism can strike it, while still locking the bit against rotation and against pulling out of the tool. The sleeve and its internal retention components are what make that happen, and Milwaukee supplies them together as a service assembly so the whole bit-retention mechanism goes back together correctly as a unit. Because the sleeve is worked on every single bit change and lives right in the path of the concrete dust the hammer produces, it is a genuine wear item. When it wears, bits begin to slip, will not lock in, become hard to insert or release, or drop out of the tool during use. Replacing it with the correct genuine Milwaukee OEM assembly restores the exact sleeve and detent geometry the SDS Plus system depends on, which is both a performance and a safety matter, since a bit that is not positively retained is a hazard.
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 placing your order, since running production changes can alter part compatibility within the same catalog number, and confirm the figure position for this assembly on your tool's current service parts bulletin using Milwaukee's online parts lookup. This assembly services the front tool holder only. If bits still fail to lock after it is replaced, the fault may lie deeper in the spindle or striker assembly, which are serviced separately, so match your symptom to the correct figure on the parts diagram before ordering additional parts. SDS Plus bits are not included with this assembly, and Milwaukee specifies a grease for the tool holder that is sold separately, so refer to your tool's parts diagram and service bulletin for the correct lubricant and any related tool-holder components and their required quantities.
