Spiral Cutter head for Rojek Ridgid R4331 13" Thickness Planer is equipped with 48 carbide inserts. Each carbide insert has 4 indexable edges. The carbide inserts are slightly angled to the board feeding, which generates a shear cut, eliminates tear-out, and leaves a better quality surface finish on softwood, highly figured hardwood. It dramatically reduces operation noise. Simply rotate the insert quarter circle if one edge is dull or nicked. You will have a new sharp edge. Discard the inexpensive carbide inserts only when all four edges are affected. No need to sharpen these inexpensive inserts. This greatly reduces downtime. Sheartak spiral cutter heads reduce three-quarters of your sanding work and consume less power. Spiral cutter heads remove short chips in a staggered way and avoid dust clog at the hood port. Dust extraction is significantly improved. Sheartak spiral cutter heads can pay back your initial investment in no time.
Spiral Cutterhead Kit includes:
* High tensile strength alloy steel cutter block.
* 40 carbide inserts installed.
* A pair of Japan sealed bearings.
* 5 extra carbide inserts & 5 extra screws free as spare parts.
* 1 Wrench
The cutting circle of this OEM version is close to that of the original cutterhead with HSS blade. The carbide inserts are removed after the dynamic balance is completed. After the cutter block is placed into the planer, install the 40 carbide inserts to the cutter block. You can cut up to 1/8" per pass maximum. A disadvantage is that you will have to spend half an hour or so to install all the carbide inserts to the cutter block.
Read through the manual and watch the short video before you install the carbide inserts.
