Product Description
The CMT300-T127 Box Joint Template is a precision-engineered routing accessory designed for use with the CMT300 Universal Dovetail Jig. Built for woodworkers who need clean, repeatable tongue joints and box joints, this red-coded template handles a dovetail size of 12.7mm (1/2") and accommodates stock thicknesses ranging from 5/16" to 25/32". The color-coded red identification system makes it fast and mistake-free to grab the right template when working with multiple joint sizes. At 300mm total length, this template delivers the reach needed for consistent, professional-grade joinery across a wide range of project applications.
Key Features
- Dovetail and box joint size of 12.7mm (1/2") - precisely matched to straight bit profiles for tight-fitting, gap-free tongue joints
- Red color-coded template body - instantly distinguishable from other CMT300 template sizes, reducing setup errors and saving time in the shop
- 300mm total length - provides full working coverage across standard workpiece widths, minimizing the need for repositioning during cuts
- Compatible stock thickness range of 5/16" to 25/32" - gives the woodworker flexibility to work with a broad variety of lumber and panel thicknesses without changing accessories
- Supplied with a precision guide bushing (11.1mm x 4mm / 7/16" x 5/32") - ensures accurate bit-to-template registration for repeatable results cut after cut
- Designed for use with straight bits - compatible with 1/2"-diameter straight router bits, meaning the template works with commonly available tooling for box joint and tongue joint work
Why This Product
- The color-coded red designation pairs with the CMT300 Universal Dovetail Jig's system design, allowing woodworkers who own multiple templates to identify and swap the correct 1/2" template immediately - no measuring or guessing at the bench.
- The included precision guide bushing (7/16" x 5/32") removes the need to source a separate guide, so the template is ready to use as a complete, matched assembly right out of the packaging.
- A stock thickness range of 5/16" to 25/32" makes this template practical for everything from thin drawer stock to heavier cabinet-grade panels, reducing the need for multiple setups or jig swaps.
- The 300mm working length and 12.7mm (1/2") joint spacing suit projects requiring evenly spaced, structurally sound box joints - a joinery method prized for both mechanical strength and visual appeal in fine woodworking and cabinetry.
