Festool HW D 64/27 S12 Mitre Tongue and Groove Cutter

At a Glance: 64mm diameter, 45° mitre tongue-and-groove cutter with a 27mm cutting length and rigid 12mm shank for strong, self-aligning corner joints.

The Festool HW D 64/27 S12 Mitre Tongue and Groove Cutter is a precision router cutter developed for producing strong, accurately interlocking 45° corner joints in furniture, drawers, boxes and cabinet components. Instead of creating a simple mitred edge that can slide out of alignment during assembly, the cutter forms matching tongue-and-groove profiles that lock the two workpieces together.

This interlocking profile greatly improves stability during glue-up by helping prevent the components from slipping sideways when clamping pressure is applied. The increased mechanical engagement also provides a larger and more effective bonding area than a plain mitre joint, resulting in a strong, neat corner with the end grain concealed inside the finished assembly.

With its substantial 64mm cutter diameter, 27mm cutting length and robust 12mm shank, the cutter is designed for controlled professional routing in suitable timber and wood-based materials. It is particularly valuable in cabinetmaking and furniture production where precise corner alignment, repeatable results and an attractive mitred finish are required.

Strong mitred corners that align securely during glue-up

The Festool mitre tongue-and-groove cutter combines the clean appearance of a 45° mitre with the strength and stability of an interlocking joint. The matched profiles guide the components into position, resist sideways movement and simplify accurate assembly of boxes, drawers and furniture carcasses.

Product Highlights

  • Interlocking joint profile: Produces matching tongue-and-groove surfaces that engage securely at a 45° corner.
  • Improved glue-up stability: Helps prevent the workpieces from slipping sideways when clamping pressure is applied.
  • Strong corner construction: Mechanical interlocking and an increased glue area create a stable, durable joint.
  • Clean mitred appearance: Conceals the board edges for a neat and professional finished corner.
  • Large 64mm cutter diameter: Provides the geometry required to machine the complete locking mitre profile.
  • Rigid 12mm shank: Supports stable cutter rotation during demanding routing applications.
  • Professional Festool quality: Precision manufactured for accurate, repeatable woodworking results.

Extra Information

  • The cutter produces complementary profiles that form a 90° corner when the two workpieces are assembled.
  • One workpiece is generally routed flat on the table while the mating component is routed vertically against a secure fence.
  • Accurate cutter height and fence positioning are essential for the two profiles to align correctly.
  • A suitable router with a 12mm collet and sufficient power for the 64mm cutter diameter is required.
  • For improved safety and control, this large-profile cutter is best used in a stable router-table setup where permitted by the router manufacturer.
  • The workpiece thickness must be suitable for the cutter&s 27mm usable cutting length.
  • The cutter is supplied in a self-service display pack.

Pro Tips

  • Use test pieces of exactly the same thickness as the finished components to set the cutter height and fence position.
  • Mark the inside and outside faces of every workpiece before routing to avoid machining a profile in the wrong orientation.
  • Route one mating component horizontally and the other vertically while keeping the reference faces consistent.
  • Make the cut in several controlled passes rather than attempting to remove the full profile in one heavy pass.
  • Use featherboards, hold-downs and suitable push aids to keep each component firmly against the table and fence.
  • Dry-fit the joint before applying adhesive and make fine adjustments until the external corner closes cleanly.
  • Apply glue evenly to the interlocking surfaces without using so much that the joint cannot seat completely.
  • Clamp the assembly evenly and check that the box or carcass remains square while the adhesive cures.

How to Use

  • Disconnect the router from the electrical supply before installing or adjusting the cutter.
  • Confirm that the router is suitable for the cutter diameter and is fitted with a clean, undamaged 12mm collet.
  • Insert the cutter shank sufficiently into the collet without allowing the collet to contact the cutter body.
  • Tighten the collet securely according to the router manufacturer&s instructions.
  • Fit and adjust a secure router-table fence, guarding and suitable workpiece-control accessories.
  • Prepare two test pieces with the same thickness as the finished workpieces.
  • Set the cutter height so that the centre of the interlocking profile aligns correctly with the workpiece thickness.
  • Route the first test piece flat against the router table and fence using several controlled passes where required.
  • Route the matching test piece vertically against the fence while maintaining the correct reference face.
  • Dry-fit the test pieces and adjust the cutter height or fence position until the corner closes accurately.
  • Route the finished components using the confirmed setup and consistent reference faces.
  • Apply suitable wood adhesive to the joint, assemble the components and clamp them square until fully cured.

Features

  • 45° cutting angle: Produces mitred corner profiles for boxes, drawers and furniture components.
  • Mitre tongue-and-groove geometry: Forms complementary profiles that interlock during assembly.
  • 64mm cutter diameter: Substantial cutter body provides the required locking-mitre profile.
  • 27mm cutting length: Suitable for routing compatible timber and panel thicknesses within the usable cutting range.
  • 12mm shank: Provides a strong, rigid connection in a suitable router collet.
  • Carbide cutting edges: Designed for accurate machining and dependable service life in suitable materials.
  • Precision profile: Allows matching workpieces to be joined accurately at right angles.
  • Self-aligning joint action: The tongue and groove help locate the components during assembly.

Benefits

  • Easier assembly: The interlocking profile helps hold the two components in their correct position during glue-up.
  • Reduced joint movement: Workpieces are less likely to slide apart or become misaligned under clamping pressure.
  • High joint stability: The mechanical connection reinforces the glued corner.
  • Attractive finished corners: Creates a continuous mitred appearance without exposed panel edges.
  • Repeatable production: Once correctly set, the cutter can produce matching profiles for multiple components.
  • Efficient cabinet construction: Combines profiling, alignment and joint preparation in one routing operation.
  • Versatile woodworking use: Ideal for drawers, boxes, furniture and cabinet carcass construction.

Application

  • Producing interlocking 45° corner joints.
  • Manufacturing drawers and wooden boxes.
  • Constructing furniture carcasses.
  • Cabinet and cupboard production.
  • Joining solid timber components.
  • Joining suitable wood-based panels.
  • Creating neat corners with concealed board edges.
  • Production work requiring repeatable self-aligning mitre joints.

Safety

  • Wear suitable eye, hearing and respiratory protection whenever operating the router.
  • Disconnect the router from the electrical supply before installing, removing or adjusting the cutter.
  • Only use the cutter with a router approved for its 64mm diameter and fitted with the correct 12mm collet.
  • Inspect the cutter body, shank and cutting edges before every use and do not use a damaged cutter.
  • Never exceed the maximum rotational speed specified for the cutter.
  • Use a stable router table, secure fence, suitable cutter guard and effective dust extraction where required.
  • Keep hands away from the cutter and use featherboards, push blocks or other suitable feeding aids.
  • Secure narrow or vertical workpieces carefully to prevent tipping, lifting or kickback.
  • Feed the workpiece against the direction of cutter rotation unless the operating instructions specify otherwise.
  • Do not attempt to remove the complete profile in one heavy pass.
  • Allow the cutter to reach full operating speed before feeding the workpiece.
  • Wait for the cutter to stop completely before making adjustments or removing offcuts.
