Corner Template CMT 12 × 15 cm — woodworking/trim jig

CMT corner template 12 × 15 cm — woodworking/trim jig is a compact template designed for marking and shaping internal and external corners in cabinetry, mouldings and panel work. The template sets fixed 12 × 15 cm dimensions to ensure consistent layout of corner profiles and to guide cuts and trimming operations. It is compatible with hand tools and routers and is intended to speed up repetitive marking and improve accuracy during joinery and finishing tasks.

Advantages

The template provides a rigid, repeatable reference for corner geometry which reduces setup time and minimizes measurement errors. Its compact footprint makes it easy to position on small workpieces and in confined spaces. The fixed dimensions eliminate guesswork for commonly used corner sizes, and compatibility with common routers and hand tools allows integration into existing workflows without special adapters.

Suitable for

• Marking and laying out internal and external corners on cabinets and furniture
• Shaping and trimming mouldings and trim boards
• Routing consistent corner profiles on panels and doors
• Repetitive workshop tasks requiring uniform corner dimensions

Key specifications

• Template dimensions: fixed 12 × 15 cm working profile
• Designed for both internal and external corner layout
• Compatible with hand tools and routers for guided cuts
• Compact and lightweight for use on small workpieces
• Durable construction suitable for repeated workshop use

How to use

Place the CMT corner template against the workpiece so the template faces align with the intended corner lines. Secure the template in position by hand or with clamps if necessary. Use a pencil or marking knife to scribe the corner profile along the template edge for layout work. For shaping or trimming, guide a router or chisel along the template edge, keeping steady pressure and following the template contour to achieve the required internal or external corner form. Verify fit and make fine adjustments before final assembly.

Usage recommendations

For best results, ensure the workpiece surface is flat and free of debris before positioning the template. Use sharp router bits or cutting edges and proceed with light passes when routing to avoid tear-out. When repeating the same corner profile, label workpieces or mark template orientation to maintain consistency across multiple parts.
