What’s a lock miter?

A lock miter router bit cuts a 45-degree miter with a tongue and groove. When correctly cut, the parts go together at a perfect 90-degree angle and the interlocking tongues and grooves make for lots of mechanical strength and glue surface area. Lock miters are also great at keeping parts aligned during assembly.Use this joint on drawers, boxes or even hollow columns like newel posts.You can cut a lock miter on end grain, as shown in our photos, or on the long grain.Almost anyplace you’d use a miter, you can successfully use a lock miter.

How to use the Lock Miter Router Bit?

If you follow the steps you’ll be able to cut perfect lock miters. Here are some tips to make it even easier(Learn on YouTube):

  • Use wide pieces. Your project parts must be cut to the right length before cutting the lock miters, but they can be any width. Leave them 1 in. too wide, and cut them to final width after you’ve done the routing. They’ll be easier to handle, and the “blowout” you get on the back of the cut will be cut off when you machine to final width. If your project calls for narrow pieces, 2 in. to 3 in. wide,machine pieces 6 in. to 7 in. wide and rip them to the size you need.
  • Use a tall fence. Holding a piece vertically against the fence is a lot easier if the fence is high. Use one that’s about 7-in. tall.
  • Use a “zero clearance” fence. Having the opening surrounding the bit as small as possible helps prevent your workpiece from slipping into the opening.
  • Precut your parts. A 2- or 3-hp router will hog all the material off in one pass, but it’s going to be a lot easier to machine the lock miter if you precut your parts on the tablesaw with a 45-degree bevel.Trim off only about 3/8 in. on 3/4-in. stock.
  • Use push blocks. Neoprene-padded push blocks will make cutting lock miters easier and safer (see Sources, below).
  • Make a permanent set up piece. When you have all the setup done, machine a piece and keep it for your next project. If you want to set up the whole operation for the same thickness of material again, use the set up piece to set the thickness of your work, the height of the bit and to position the fence.You’ll still need to do some test cuts and some final tweaking, but you’ll be darn close.
