The helical Cutter head for Porter Cable 6-inch (152 mm) Variable Speed Bench Jointer PC160JT is installed with 20 carbide inserts. Each insert has four R150 round edges. The inserts are seated at a slight angle to the boarding feed, which generates true shear-cut, eliminates tear-out, and leaves a glossy surface finish on any wood, to or against the grain of boards. As the carbide inserts cut at a small portion of the 15mm length in a staggered way other than the direct strike on board as long straight blades of a conventional cutter head, noise is hugely reduced during option. When one edge is dull or chipped, loosen it, clean it and the seat up, turn it 90 degrees to reveal a new edge, and tighten it up. You now have a new sharp edge in minutes. Only replace the inserts when four edges are affected. This greatly reduces your downtime. The inexpensive carbide inserts are standard sizes and easy to acquire. Due to the quality cut, your sanding work is reduced by three-quarters. The life use of carbide inserts is 50 times of the high-speed steel blades. Spiral cutter head consumes less power than a cutter head with HSS blades. These features make retrofitting much cheaper. As the spiral cutter head removes short strips of wood, dust extraction becomes much easier, and clog at the hood fort never happens even if your dust collector is not powerful enough or well designed. Upgrade your planer now and it will pay back your investment in no time.
