The helical cutterhead on this planer provides smoother cutting and a finer finish than conventional knives, and the 74 four-sided indexable carbide knife inserts do not require adjustment after installing. Three V-belts transfer maximum power from the 3HP motor to the cutterhead. Your workpiece will get substantial support from the precision ground cast iron table and two large extension wings. The 4" dust port angles the collection hose away from the work area. Stock return rollers atop the machine speed repetitive cuts. The serrated steel infeed and smooth steel outfeed roller allow for 1/8" maximum depth of cut and trouble-free operation. A 2-speed gearbox features an automatic chain tensioner. The one-piece welded steel stand has built-in lockable casters for easy movement around the shop.
