Use the reversible 45° lock miter glue joint router bit to join boards at 90°. The interlocking 45° cuts will produce extremely strong joints without having to struggle to keep the boards in place during clamping. Additionally, it will provide extra gluing surface resulting in an extremely strong and durable joint. When positioned properly, the bit will cut both pieces of stock without having to adjust the bit. Simply set the center of the stock to the center of the bit. Then, cut one piece horizontally and the second one vertically. Use with stock ranging from 1/2" to 1". Two flute carbide cutters & 1/2" shank.
