Upgrade your Spiral Cutter head for General 4801MZ 8" Jointer with 40 carbide knives for the following benefits. * Better quality finish with no tear-out. All the inserts are angle d along the helical in a staggered way and make shear-cut effects on the boards. This leaves a very smooth finish better than 180# grit sanding belt works. It reduces your sanding work by three quarters. * Noise is hugely reduced as the spiral cutter head keeps constant contact to the board with only a few knives. * All the cutters are made of solid tungsten carbide which is much harder and stayer sharp longer than high speed steel blades. If one edge is chipped or dull, rotate it 90° for a new sharp edge. Each insert has four cutting edges and can be used four times. * Easy to set up. The indexable carbide inserts are precision ground to a very tight tolerance and are interchangeable. Loosen the screws, rotate 90°, tighten the inserts in minutes. The inserts can be precisely positioned by the taper hole style locking. * Smaller carbide inserts remove shorter and thinner materials, which make dust extraction much easier. * For the long term, spiral cutter heads are cheaper to use and cany pay for itself in a very short time. Standard Kit Includes: * High tensile alloy steel cutter block * 40 Carbide Inserts Installed * 5 Additional Carbide Inserts and 5 screws. * 1 Torx head T type key Show more
