Choose the Correct Fit
Match the adapter to the specified SDS-Plus masonry core system. Check the exact core-body part number and the hammer’s diameter capacity.
Allow room for the 18 in adapter and the complete tool setup. Check the core body’s usable depth separately from adapter length.
Installation & Care
Isolate the hammer before fitting the adapter, core body or centering bit. Check each connection and follow the starting procedure for the assembly.
Clean debris from the threads after use. Inspect the adapter and centering-bit attachment, and replace damaged parts before the next hole.

Important Product Questions
Does this fit every SDS-Plus core body?
SDS-Plus identifies the hammer connection, not every core-body thread. Confirm that the core body belongs to the matching two-piece masonry core system.
Does the adapter length equal the cutting depth?
No. 18 in identifies this adapter. The matching core bodies have their own usable depth and require core removal for deeper holes.
Which centering bit matches these adapters?
Milwaukee lists centering bit 48-20-3580 for adapters 48-20-3582 and 48-20-3593. Check the pilot and its mounting parts when assembling the setup.
