Upgrade your GRIZZLY G1033 20-inch Planer with spiral cutterheads for the following benefits. Industrial Standard Spiral Cutterhead with 132 carbide inserts on 6 spirals. It is highly recommended for daily operation in woodworking shops. 

* Better quality finish with no tear-out. All the inserts are angled along the helical in a staggered way and make shear-cut effects on even highly figured hardwood.

* Noise is hugely reduced as the spiral cutter head keeps constant contact with 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 can pay for itself in a very short time.

Spiral Cutterhead Kit includes:

* High tensile strength alloy steel cutter block.

* 132 carbide inserts installed on 6 spirals
