Carbide Reversible Knives

Reversible knives have two to four cutting edges, when the blade becomes dull, just loosen the screw fastening the blade, rotate and retighten it, so as to save working time and do not need to re-clamp the tool, another important feature of the reversible knives is that it has no wear of blade edge and strictly ensures the tolerance.

UKO’s woodworking carbide reversible knives are high-performance, use solid carbide micro-grain tips give superior tool life in a wide variety of materials for all general joinery in hardwoods and softwoods.

Woodworking cutting tools carbide reversible knives, indexable knives suitable for different cutting heads and spiral planning cutter.

What is the purpose of woodworking reversible knife?2021-10-20T03:39:13+00:00

Woodworking carbide reversible knives(or reversible inserts) are used on a spiral cutter head for wood planing. The four sides of the blade can be turned over and used after other sides get blunt.

What are the types of woodworking discarded spiral knives?

  1. Floating type: the blade is directly attached to the blade body and locked directly
    Block type: the blade is erected and locked on the blade body by the block
  2. Light cut (suitable for playing cork): with 14 * 14 * 2.0 straight blade floating stickers
    Heavy cut (suitable for playing hard and soft wood):
  • With 15 * 15 * 2.5 straight blade floating stickers
  • With 15 * 15 * 2.5 / R150 circular blade floating paste models
  • With 30 * 12 * 1.5 straight blade pressing block
