Upgrade for RIDGID 6-inch jointer (models JP0610, JP06101, JP6101, JP06000) with this high-performance helical cutter head. Engineered to replace the original G6/63 cutter head, this spiral carbide insert head transforms your jointer into a smoother, quieter, and more efficient woodworking tool. The cutter head is machined with 5-axis CNC technology for exceptional coaxiality and balance. Its 30 tungsten carbide inserts are positioned at a precise angle to provide a true shear cut, virtually eliminating tear-outs and kickbacks while delivering a flawless surface on even the hardest woods. With a noise reduction of over 50%, this upgrade creates a more comfortable working environment. The carbide inserts last up to 40 times longer than standard blades and require no sharpening—replacement is quick and requires no adjustments. Additionally, the helical design produces finer chips, optimizing dust collection efficiency. The kit includes everything needed for installation: cutter head, inserts, screws, screwdrivers, and pre-installed bearings. For optimal performance, tighten inserts to 6 Newton-meter torque as guided in the manual. Additionally, the helical design generates smaller wood chips, optimizing dust collection efficiency. The knives are easy to replace without adjustments, and each insert is pre-designed with a radius-corner to prevent surface lines and chipping. Each kit includes everything needed for installation: a 12" helical cutterhead, 38+2 carbide inserts, 38+2 screws, 2 bearings, and 2 wrenches. For torque specifications (6 Nm), refer to the included manual.
