Milwaukee Chuck Sleeve
Model Number: 42-76-0066
The Milwaukee 42-76-0066 is a genuine OEM Chuck Sleeve for the 2912-20 M18 FUEL 1 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, the sleeve works with the tool holder's locking elements to engage the grooves in an SDS-Plus bit shank, and the SDS-Plus system 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 chuck sleeve is the part the operator handles to load and unload bits, so it must move and return correctly for the tool holder to grip and release bits reliably. 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 is worn, cracked, or no longer returns properly, bits become hard to insert or release, may not lock in, or can drop out during use. Replacing it with the correct genuine Milwaukee OEM chuck sleeve restores proper, secure bit retention.
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. This chuck sleeve is specified for the 2912-20 M18 FUEL SDS-Plus Rotary Hammer, so confirm your tool's catalog and serial number against the parts diagram before ordering. Note that Milwaukee also offers chuck sleeve service assemblies that supply the sleeve together with its internal tool-holder components as a unit, so if your repair calls for the complete tool-holder assembly rather than the sleeve alone, confirm which part your diagram specifies. The locking balls, springs, retaining rings, and other tool-holder components that work with the chuck sleeve are separate parts, and Milwaukee specifies grease for the tool holder that is sold separately, so refer to your tool's parts diagram for the correct companion part numbers and the specified lubricant. Because positive bit retention is a safety function on a rotary hammer, restore the tool holder to correct working order when servicing the sleeve.
