Product Description
Milwaukee SDS+ PLUSLOK 12 in. Extension
Model Number: 48-20-6940
The Milwaukee 48-20-6940 is an SDS+ PLUSLOK 12 in. Extension — a 12 in. shaft extension for Milwaukee SDS+ rotary hammers that allows SDS+ drill bits and chisels to reach drilling and chipping locations beyond the hammer's natural working reach without switching to longer individual bits. The PLUSLOK connector is built directly into the extension body as an integrated design rather than a separate coupling accessory — this integration provides a more compact overall connection profile than external coupling designs and maintains the SDS+ engagement geometry that ensures the extension-bit interface functions like a direct SDS+ bit engagement in the hammer's chuck. The extension connects between the SDS+ hammer's chuck and the working SDS+ bit, adding 12 in. of working length between the hammer body and the bit tip for applications where the drilling location is in a structural element, wall cavity, or floor section deeper than the standard bit can reach from the accessible drilling position.
The 12 in. extension enables drilling through double top plates, multi-member floor assemblies, and deep CMU block sections using standard-length SDS+ bits rather than requiring the purchase of extra-long specialty bits for each diameter needed — a significant accessory efficiency for rotary hammer operators who drill multiple anchor diameters and only need extension reach occasionally rather than on every hole. The PLUSLOK connection maintains the full SDS+ bit rotation and hammering action transmission through the extension without the energy loss, vibration, or bit wobble that extension designs with inadequate coupling rigidity produce. Compatible with Milwaukee SDS+ rotary hammers and the full range of Milwaukee SDS+ drill bits for concrete, masonry, and other hammer drilling applications.
Also available in 24 in. extension length for even deeper reach requirements — see Milwaukee's complete SDS+ accessory lineup for extension and adapter options.
