MNA 45 Degree Lock Miter Router Bit 3-Piece Set, for 1/2”, 5/8”, 3/4” Cutting Height, 1/4 Inch Shank. Easy to Create Lock Miter Joint

They look well constructed, but haven’t had the opportunity to use them yet.

Received the set today. Came nicely packed. Cardboard box with a plastic insert and cover. Not a fancy wood box but should do for a while. Had some 5/8 pine to run. Mounted the 3/4 sized bit in the router table. Adjustment was pretty easy. Set the height using the midpoint of my workpiece and eyeballed the fence into position. Fine-tuned the fence position running the stock vertically that the bevel ended at the stock edge. Ran the complementary piece and the fit was off slightly. Raised the bit 1/64 and moved the fence forward the same amount. I hit the magic combination for my material. The bit cut cleanly and the pieces glued up beautifully. Take your time with setup and use featherboards. Have enough spare material to test during setup. Youll be pleased with the results. These bits are a good value.
