Choose the Correct Fit
Choose the opening from the pipe or conduit outside diameter and required clearance. Confirm the drill’s boring capacity.
Inspect the hole path for concealed services and metal. Secure the work and use the drill’s required support handle.
Installation & Care
Disconnect power before fitting or servicing the bit. Secure the three-flat shank and inspect the feed screw.
Control the self-feeding pull without forcing a dull cutter. Clean and dry the bit after use, then inspect the cutting edge.

Important Product Questions
Can the cutting edge be sharpened?
Yes. This standard Selfeed bit has a resharpenable cutting edge. Preserve the original cutting geometry and follow the manufacturer’s service guidance.
Which wear parts can be replaced?
Milwaukee identifies both the feed screw and arbor as replaceable on this large Selfeed bit. Match replacements to this exact model before servicing.
Does nominal pipe size equal the hole diameter?
Not necessarily. Use the pipe or conduit’s actual outside diameter and required installation clearance to choose the hole size.
