Milwaukee 1/4 in. Hex Anvil Assembly
Model Number: 42-06-2659
The Milwaukee 42-06-2659 is a genuine OEM 1/4 in. Hex Anvil Assembly for Milwaukee M18 impact drivers, including the 2656-20 and 2657-20. The anvil is the output drive component of the impact mechanism: it is the 1/4 in. hex drive stub that receives the impact blows from the hammer and transmits them to the driver bit through the hex socket and quick-change retention mechanism. The 1/4 in. hex format accepts all standard 1/4 in. hex shank impact driver bits, including Phillips, Torx, square, and nut driver bits, and the quick-change retention mechanism in the anvil allows tool-free bit changes with one hand. This is a complete anvil assembly: it includes the anvil and its sleeve along with the spring, retaining ring, washer, and two steel balls that make up the bit-retention mechanism, so the working retention system is replaced as a matched unit. Because the anvil takes the full repeated impact of the driver and its hex bore and retention parts wear with use, a worn anvil, a damaged hex bore, or a retention mechanism that no longer holds bits securely causes bits to slip, wobble, or fall out and reduces driving performance. Replacing it with the correct genuine Milwaukee OEM anvil assembly restores full impact driver output and 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 anvil assembly is specified for the 2656-20 and 2657-20 M18 impact drivers and is referenced across the M18 impact driver family, so confirm your tool's catalog and serial number against the parts diagram before ordering. Note that this assembly includes the anvil, sleeve, spring, retaining ring, washer, and two steel balls, but does not include the outer collar; a screwdriver and pliers are typically needed to replace it. The hammer, impact mechanism, and gearcase components that drive the anvil are separate parts, so refer to your tool's parts diagram for the correct companion part numbers, and lightly grease the anvil with the Milwaukee-specified grease where the diagram directs on reassembly.
