The upgraded insert knives feature a radius-corner design that eliminates lines and scalloped surfaces and lowers the risk of blade breakage. This helical cutter head is built to last with a premium steel body that has been black oxidized for superior rust protection

The helical head perfectly fits the DELTA 37-190 37-195 37-196 37-275X 37-866X 52-858 52-866X 6″ jointers. The tungsten carbide insert knives are made from 100% raw material, so compared with HSS blades, this helical cutter head produces a better wood surface finish without kick-backs and tear-outs.
