Choose the Correct Fit
Identify the core body and inspect its retaining-ring style. Use this part only where the centering-bit fitting matches the specified design.
For a Milwaukee SDS-Max core with a red retaining ring, select kit 48-20-5498 instead. Confirm the exact fitting on spline cores separately.
Installation & Care
Isolate the hammer before changing the centering bit. Follow the core-body instructions and check that the bit is fully retained before starting.
Use drift key 48-20-5497 where specified to release this centering bit. Let it cool, clear debris and inspect the tip before reuse.
