Choose the Correct Fit
Check both connection diameters and the mating thread pitches before ordering. The listed diameters alone do not establish compatibility with every core drill.
Apply anti-seize lubricant to the threads before use. Keep the mating surfaces clean so the adapter can seat as intended.
Installation & Care
Inspect the adapter and mating threads for damage before assembly. Use the flat-sided section when the equipment instructions call for wrench assistance.
Follow all core drill and bit instructions for support, operating mode and cooling. Confirm the complete setup before starting a hole.

Important Product Questions
What are the two connection sizes?
Milwaukee identifies a 5/8-inch female interface and a 1-1/4-inch male interface.
Are thread pitches specified here?
The verified manufacturer listing gives the two diameters but does not establish both pitches. Confirm the complete thread specifications on the mating equipment before ordering.
How should the threads be prepared?
Milwaukee directs users to apply anti-seize lubricant to the threads before use.
