Choose the Correct Fit
Match the SDS-Max hammer fitting, thick wall core system and 1-1/2–6 in size group. Shank type alone does not establish core-body fit.
Check working clearance for the 18 in adapter. For extra reach, confirm extension 48-95-6085 against the complete assembly.
Installation & Care
Isolate the hammer before assembly. Clean the mating parts, fit the correct core body and check that the hammer connection is retained.
Remove debris after use and inspect both ends for damage. Replace a bent or worn adapter before further coring.

Important Product Questions
Will this shank work with a different wall-style core?
It is listed for the thick wall system and 1-1/2–6 in core sizes. Use the adapter assigned to the exact core body rather than selecting by hammer fitting alone.
Does adapter length tell me how deep the core body cuts?
No. 18 in describes this adapter. The separate core body has its own usable cutting depth, and deeper holes may require repeated core removal.
Which extension belongs to this setup?
Extension 48-95-6085 is listed with this core system. Confirm the assembled reach, core diameter and hammer capacity before drilling.
