The Laguna 8” Wedgebed Jointer ShearTec II Cutterhead is the perfect “step-up” jointer with increased capacity for serious woodworking.The oversized tables provide plenty of support to easily flatten long, wide boards while the large center mounted cast-iron fence allows for maximum stock support when edge jointing.The cast-iron in-feed and out-feed tables feature independent adjustment on dovetail ways.The Laguna ShearTec II is at the cutting edge of Spiral Cutterhead technology today. Deep gullets allow chips to exit fast & keep the head clean. The inserts are made from thicker solid German carbide & set into the head on a flat surface rather than a cone design. This allows more torque to be used when tightening the inserts. All of the inserts are slightly angled to give a shear type cut with low impact & less kick-back action. The leading edge is crowned to minimize lines appearing.Laguna ShearTec II heads are all 6 row; most competitors’ heads offer just 3 or 4 rows. There obviously are a host of benefits associated from the additional rows: More carbide inserts, longer life, less noise and vibration, less kick-back & smoother finish.
