Festool HW D 64/27 S12 Mitre Tongue and Groove Cutter 45°

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.
