CMT Drawer Lock Router Bit - 1-1/4" Diameter, 1/2" Cutting Height, 1/4" Shank is a precision-ground joinery bit engineered for constructing strong, tight-fitting drawer lock joints in cabinetry and furniture work. Built by CMT, this carbide-tipped bit gives woodworkers the means to mill perfectly interlocking drawer fronts and sides quickly and consistently - producing professional-quality results on a router table. Whether you are assembling solid hardwood drawer boxes or working with composite sheet goods, this drawer lock bit is designed to cut cleanly and hold its edge through demanding production use.

Key Features

• 2-tooth carbide-tipped (HW) cutting head - hard-wearing industrial carbide maintains a sharp edge longer, reducing the need for frequent resharpening and keeping joints clean and accurate over time.
• 1/4 in. shank diameter - fits a wide range of router table collets and keeps the bit secure during the two-pass drawer lock joint milling process.
• 1/4 in. cutting height with a 1-1/4 in. overall diameter - sized specifically for drawer lock joint geometry, ensuring proper material registration and a snug mechanical fit between drawer fronts and sides.
• Compatible with material thickness from 5/8 in. to 1 in. - accommodates common drawer-box stock dimensions without the need for bit swaps or extensive setup changes.
• Right-hand (RH) rotation - matches the standard feed direction used on router tables, making setup straightforward and predictable.
• Router table use only - this design is optimized for table-mounted routing where the workpiece can be properly registered face-down or vertical against the fence, ensuring accurate, repeatable joint cuts.

Why This Product

• Purpose-built for drawer lock joinery - the bit geometry is specifically designed to mill both the drawer front (inside face down on the table) and the drawer sides (inside face vertical to the bit and fence) in a single setup, making the joint-cutting process fast and repeatable without custom jigs.
• Handles a practical range of drawer stock - with a maximum thickness capacity of 5/8 in. to 1 in., this bit works with the most common solid wood and sheet-good thicknesses used in cabinetry, reducing the need for multiple bit sizes across typical drawer builds.
• Carbide-tipped construction (HW material) means the cutting edges stay sharp through extended runs of hardwood or composite material, helping woodworkers maintain joint quality across an entire batch of drawers.
• Two-tooth configuration balances cutting speed and surface quality - fewer teeth at a given diameter produce a smooth shear cut through wood fibers, which translates to cleaner mating surfaces and joints that glue up tightly without excessive prep work.
