The ShearTec II cuttherhead comes as standard equipment on PX|22 ShearTec II Jointer. The ShearTec II is a 6-row carbide insert cutterhead that produces a superior surface finish on all woods including challenging hardwoods. The ShearTec II knives and fasteners have a T-step design to maximize clamping force on the knives preventing knife cracking and chatter. The 4-sided carbide insert knives produce a shear cut for flawless results. The ShearTec II cutterhead has deep grooves that make the cutterhead very quiet and improve shaving ejection. The 4-sided knives can be rotated for a new cutting edge without need for a knife setting jig.
