CMT Drawer Lock Router Bit - 1" Diameter, 1/2" Cutting Height, 1/2" Shank by CMT is a precision-machined, carbide-tipped joinery bit engineered for creating strong, interlocking drawer lock joints with a single router table setup. Designed for woodworkers and cabinet makers who demand tight-fitting, durable drawer construction, this bit mills both the drawer front and drawer sides with repeatable accuracy - making it an essential tool for quality cabinet joinery work. The 1" diameter profile and 1/2" cutting height work together to produce joints that hold firmly in solid hardwood and panel materials ranging from 3/8" to 5/8" thick.

Key Features

• 1" Cutting Diameter with 1/2" Cutting Height - delivers the full drawer lock profile in a single pass, eliminating the need to reposition or change bits mid-operation and saving significant setup time.
• 1/2" Shank - the larger shank diameter reduces vibration and chatter during the cut, resulting in smoother joint surfaces and a more consistent fit between drawer components.
• 2-Flute Carbide-Tipped (HW) Design - two hardmetal carbide cutting edges provide clean, chip-free cuts in hardwood, softwood, plywood, MDF, and similar materials, maintaining sharpness over extended use.
• Right-Hand (RH) Rotation - standard right-hand rotation is compatible with the vast majority of router table setups, making this bit a straightforward drop-in addition to existing workshop equipment.
• Maximum Material Thickness of 3/8" to 5/8" - accommodates a practical range of drawer box stock thicknesses, giving woodworkers flexibility to work with various panel and solid wood dimensions without swapping bits.
• Router Table Exclusive Use - engineered and optimized specifically for router table operation, ensuring controlled, repeatable results and consistent joint geometry on every workpiece.
• Total Length of 2-9/64" - compact overall length keeps the bit stable in the collet and reduces deflection during heavy cuts, contributing to joint precision and longer tool life.

Why This Product

• The drawer lock profile allows you to mill the drawer front face-down and the drawer sides vertically against the fence - a simple, two-position workflow that produces strong, self-aligning joints without complex jigs or fixtures.
• With a working range of 3/8" to 5/8" material thickness, this bit handles the most common drawer box stock dimensions used in residential and commercial cabinet construction, reducing the need for multiple specialized bits.
• The 2-flute hardmetal carbide construction is purpose-built for joinery applications where clean shoulders and crisp corners are critical to joint fit - sloppy cuts mean loose drawers, and sharp carbide edges help prevent that outcome.
• Restricted to router table use by design, this bit delivers the stability and feed-rate control that drawer lock joints require - producing consistent, repeatable results across production runs of multiple drawer boxes.
