Whiteside 45 Degree Lock Miter Bit
The 45 Degree Lock Miter Bits from Whiteside are some of the most useful bits in your shop. Virtually anywhere you could use a miter, you could use a lock miter bit to create a beautiful joint that is strong and very easy to assemble. Not only does this cutter create a perfect 45 degree cut, but it also adds a tongue and groove element that strengthens the joint and makes assembly a breeze.
Wedge shaped tongue and groove joints are a little simpler to make than the straight variety which requires a near perfect match to make a strong joint.
This particular Whiteside brand set is designed for material from 5/8” to 1-1/4” thick. Both cutters are 1/2" shank. These bits do not have a ball bearing and as such should be used with a simple split fence on a router table. (The Woodpecker LE Fence is well suited for this application.
