UJK Solid Carbide Upcut Spiral Router Cutter - 6 mm x 22 mm (6,35mm Shank) - Right-Hand Rotation, Upcut (RH/Upcut)

This professional solid carbide upcut spiral router cutter from the British brand UJK, with a 6 mm cutting diameter, is a premium-grade tool engineered for highly efficient and clean machining of wood and plastics. Manufactured in the UK from a single monolithic piece of solid tungsten carbide, this cutter offers exceptional wear resistance and outstanding rigidity during demanding tasks. The upward-pointing helix ensures that chips are instantly cleared from the cut, preventing the cutting edges from overheating and guaranteeing an excellent surface finish.

Technical Specification

• Body and blade material: Solid Carbide

• Cutter type: Spiral Upcut (upward chip ejection)

• Rotation: Right-hand positive (RH/Upcut)

• Cutting diameter (D): 6 mm

• Cutting length (X): 22 mm

• Shank diameter (S): 6,35mm

• Blade geometry: High-precision twin-flute helix

• Material compatibility: Hardwood, softwood, MDF, plywood, chipboard, plastics

• Country of manufacture: United Kingdom (UK)

Applications

• Creating precise mortises and grooves with a 6 mm width for joinery connections, including perfect compatibility with the UJK Loose Tenon joinery jig system.

• Routing deep grooves and channels in solid wood (both hardwood and softwood) and wood-based materials such as MDF, plywood, or chipboard.

• Cutting circles and routing arcs using routing jigs and compasses (fully compatible with the Parf Circle Cutting Jig – SKU: 10018).

• Template routing and guide bush work, where maintaining perfect edge geometry and a constant cutting diameter throughout the entire working length is required.

• Efficient cutting and sizing of components using hand-held routers and CNC routers equipped with 6,35mm collets.

Key Advantages

• Excellent upward chip clearance (Upcut design) – the spiral geometry of the flutes acts like a drill bit, effectively pulling chips and dust out of deep cuts. This prevents chip clogging, eliminates the risk of burn marks on the edges, and significantly reduces the load on the router motor.

• Extreme rigidity of solid tungsten carbide – the monolithic carbide structure eliminates vibration and chatter, directly translating into flawless dimensional accuracy. The cutter retains its sharpness up to several times longer than traditional High-Speed Steel (HSS) alternatives.

• Cleaner cuts and smooth edges (Shearing Action) – the angled orientation of the spiral blades allows the tool to slice through wood fibers gradually rather than chopping into them. This minimizes the risk of tear-out and splintering, ensuring a perfect finish, especially on the bottom side of the workpiece.

• Perfect fit for the UJK Loose Tenon system – the dimensions of the cutter (6 mm diameter) are precisely calibrated for creating joints for 6 mm loose tenons, eliminating the need for test cuts and manual adjustments.

• High comfort and working safety – the optimized helix angle reduces cutting resistance and workshop noise levels, resulting in less hand fatigue and more stable control over the power tool.
