13.8 x 13.8 x 2.5mm Tungsten Carbide Replacement Tips, Extended Edge Life

Manufactured in the UK by Xcalibur Tooling, these premium 13.8 x 13.8 x 2.5mm tungsten carbide tips are engineered for compatibility with spiral cutterblocks requiring this precise insert size. Suitable for professional joinery, cabinet making, and woodworking workshops, these inserts are trusted by professionals seeking consistent, long-lasting performance from their spiral planers and thicknessers. Each pack contains 10 precision-ground, four-sided reversible knives, offering extended use and reduced downtime.

Produced from T10MG grade tungsten carbide, these inserts deliver a hardness of 92 HRA and maintain edge integrity across both hardwoods and softwoods. T10MG is selected for its superior wear resistance and toughness, outperforming standard micrograin carbide in abrasive and resinous timbers. Each tip features a 30-degree ground bevel for optimal cutting efficiency and a 150mm/90mm radius edge, which minimises tear-out and produces a smooth, ripple-free finish. The carbide is vacuum sintered, heat-treated, and stress-relieved to ensure maximum structural integrity and resistance to chipping, even under heavy, continuous use.

All inserts are precision-ground to a tolerance of ±0.01mm on all faces. This ensures a consistent knife set, correct seating within the cutterblock pocket, and stable operation at high rotational speeds. The uniformity across each pack reduces vibration and eliminates the risk of uneven planing or surface ridges. Xcalibur Tooling’s manufacturing process guarantees that every tip meets strict dimensional and edge quality standards, supporting a smooth installation and reliable performance across all compatible spiral cutterblocks.
