Porter Cable 42941 5/16 I.D. X 7/8 O.D. Replacement Router Bit Bearing. Keep your ball-bearing piloted router bits performing at their peak with replacement pilots. Over time, the ball-bearing pilot on a router bit becomes less efficient as it goes through normal wear or is contaminated with debris. Replacing the pilot will keep the bit moving smoothly, providing a more accurate cut and a smoother finish. Replacement bearings can also be used to vary the profile of a bit by changing the cutting width when a larger than standard bearing is used. Includes one ball-bearing pilot.
Porter Cable 42941 Features:
- Ball-bearing construction for smooth operation
- Replaces original pilot, installs easily using existing screw
- Delrin collar prevents scratching of solid surface materials
