This heavy-duty thickness planer features 120V AC 15 amp and a 10 000 RPM three-knife cutter-head. Built-in carriage lock prevents snipe by assuring minimal carriage movement on four posts while material is feeding. The 19-3/4-in cast base delivers two times the rigidity of existing planers with folding tables. For better surface finish and longer knife life. Also features fan-assisted chip ejection which prolongs knife life and assists dust collection with chip removal.
