- • Cutting Quality: Sharp, smooth cuts thanks to C3 micro-grain tungsten carbide and a 3-tooth T profile
- • Best for: DIYers and cabinetmakers needing repeatable tongue-and-groove joints for panels and flooring
- • Not ideal for: Cutting ferrous metals or non-wood materials such as steel and iron
Two 1/4-inch shank tongue-and-groove bits provide a 1-3/4-inch cutting diameter. Hardened steel bodies and carbide cutters are designed specifically for woodworking joints.
Tight, professional joints – with C3 micro-grain tungsten carbide cutters
C3 micro-grain tungsten carbide maintains a sharp edge and tolerates the heat of routing, while the T-shaped 3-tooth profile slices cleanly to form matching tongue and groove profiles. Carbide tips mounted on hardened steel bodies resist chipping and keep the profile crisp over repeated passes.
Consistent, snug-fitting joints reduce sanding and planing work. Suitable for cabinets, drawers, doors and flooring where neat seams matter.
Durable, stable cuts – with solid hardened steel bodies and anti-kickback design
Hardened steel bodies add rigidity to the cutter assembly and the anti-kickback geometry reduces chatter during plunging or edge routing. Reduced vibration helps the carbide tips cut more smoothly and last longer.
Longer tool life and fewer re-cuts mean less downtime in a busy workshop. Cleaner edges result in faster assembly and finishing.
Customisable fit – thanks to included bearings and spacers
Four bearings and six spacers allow incremental adjustment of the tongue and groove spacing and help set accurate cutting depth with a 1/4-inch (6.35mm) shank compatible with standard routers. The set supports a 1/2-inch cutting depth and 1/4-inch tooth width for repeatable profiles.
Quick to dial in the joint fit for varying panel thicknesses and wood species. Works well for edge-to-edge splicing and on-site adjustments.
