Rabbeting Bit

By Brad Holden

I got in a pickle the other
day when I needed to rout a
curved rabbet that was 9/32"
wide. None of the bearings
with my rabbet bit set would
work. There’s a classic solution
to this problem: You can place
a bearing—of any outside
dimension—on the shaft of a
rabbeting bit, then hold the bearing in place with a
locking collar from Whiteside, the bit manufacturer.
Ride the bearing against a template and you’re all set.

Locking collars are available for 1/4" or 1/2"
shank bits. Bearings with a 1/4" or 1/2" ID and ODs
of many different sizes are available from McMaster-Carr (



Whiteside Machine Co.,, 800-225-3928, Bearing
Lock Collar 1/4", #LC-1/4, $3; Bearing Lock Collar 1/2", #LC-1/2, $3.
