Key Features

Four cutting edges: Each insert has four sharp, precision-ground edges that can be indexed (rotated 90°) or reversed to extend tool life 4× compared to single-edge blades
Tungsten carbide construction: Made from C-2, C-4, FK07, FK08, or FK30UF grade cemented carbide for high hardness (91–94 HRA / 1750 HV10), wear resistance, and long service life
No sharpening required: Inserts are disposable/indexable—when one edge dulls, simply rotate or flip the insert to a fresh edge; no grinding or sharpening
High precision geometry: Manufactured to ISO standards with tight tolerances for outstanding surface finish and minimal tear-out on wood and board materials
Versatile applications: Suitable for particleboard, MDF, HDF, hardwood, softwood, melamine, laminates, and composite boards
