TC Blades - Form D

Knives are available in 3 profiles: Form A, Form B and Form D
Form A: TC insert with centre point and ground-in spurs. For hardwood and laminated or non-laminated boards.
Form B: TC insert with centre point and bevel wings. For hard plastic coatings (laminates). Gives improved hole quality and longer life.
Form D: TC insert (single-sided) with centre point and bevel wings. Special form for machine speeds over 12,000rpm (e.g. hand routers). Increased relief angle prevents over–heating, scorching and rapid blunting of cutting edge.
