SCM  20" Heavy Duty Planer, 7.5HP - Spiral Cutterhead - P508HV (3PH)

The Cantek P508HV 20” Planer has a solid steel helical cutterhead with two-sided carbide knife inserts that require no adjustments when changing. With a digital readout and simple PC controller, setting the table height is quick, accurate, and easy. The frame is made from heavy cast iron with known vibration damping resulting in long bearing life and superior cut quality. The planer’s segmented, serrated infeed roll & segmented pressure shoe ensures material is held firmly during the feeding and planing process 

The P508HV planer has a quick-set micro-adjustable lever that easily raises and lowers the table rollers to aid in the feeding of difficult to feel wood.  The industry standard 30×12×1.5mm carbide insert knives are positioned by two pins and held buy a gib and screw which do not require any special tools to set the height.

The knives have a slight bevel in the corners which provide for a superior finish without any stepping between the knives.  In addition, the knives sit vertically into the head which produces a proper cutting angle and gulley to allow for superior cutting depth.
