Choose the Correct Fit
Match the diameter to the opening and verify the cup-to-arbor thread. This threaded cup needs a separate compatible drive setup.
Support fragile material and check the intended hole path. Follow the saw and arbor instructions for centering and starting the cut.
Installation & Care
Use the specified drill mode, speed, pressure and cooling method. Do not assume impact or hammer operation is permitted.
Disconnect power before removing the core or changing the saw. Inspect the diamond edge and clean the cup and arbor threads.

Important Product Questions
Does this cup have an integral hex shank?
No. Milwaukee’s exact-part catalogue identifies it as a threaded hole saw. Use a compatible arbor or manufacturer-specified adapter.
Will the large retractable-starter arbor fit every size?
No. Check the arbor’s thread and minimum saw diameter. A shared diamond-hole-saw family name does not establish compatibility.
How can I reduce cracking or chipped edges?
Support the material, use the specified centering and cooling method, and avoid excessive feed pressure or side loading. Check the exact substrate before cutting.
