Specialized Router Bits: Screw Slot Bits for Cutting Countersinks and Counter-Bores
posted on December 1, 2008 by Bill Hylton
Screw Slot Bits from MLCS These Screw Slot Bits from MLCS allow your router to replace a drill press in cutting quick, accurate screw slots.

Making slots for screws — rather than simply drilling around pilot holes — is sometimes essential to allow for wood movement or for adjustability. But making those slots can be really putzy.

Countersink cut with a router bit One slot cutting bit will cut a slot with a countersink for laying in the screw.

Did you know you can get a router bit to cut those slots? Two, in fact: one to make a slot with a countersink for a flathead screw, another for a counterbored slot for a roundhead screw. Both are proportioned for #8 screws.

Counterbore cut screw slot Another bit is capable of cutting the counterbore slot for a #8 screw, and along with a plunge router can make blind slots.

Use the bit in a plunge router (or in a table-mounted router) to cut a slot in one quick operation.
