The model 30-300HC M1 20-inch planer with Magnum helical cutter head from General International is an excellent choice for schools or for anyone performing light to medium industrial applications. The bottom motor mount design of the 30-300HC M1 allows for top return rollers and easier cutter head access for knife changes, and the 5-inch dust chute is angled and offset to avoid interference with the workpiece. The 30-300HC M1 is equipped with an industrial quality 5 HP 220 volt motor and a magnetic safety switch. The large full cast-iron front and rear extension tables give the unit the look and feel of larger machines, and the extra support they provide is ideal for longer workpieces. The fully enclosed one-piece steel base has built-in lockable wheels to make the 30-300HC M1 mobile and easy to move in shops with space limitations. The 30-300HC M1 has General Internationals’ unique Magnum Helical cutter head running at 5000 RPM and featuring 4 rows with a total of 58 double sided carbide inserts, for smoother planing, longer service life, easier blade changes, and with less operating noise than traditional full width planer knives. The 30-300HC M1offers two feed speeds, 16 or 20 feet per minute, for smooth planing results in both soft and hard woods. The 30-300HC M1 can plane stock having a minimum length of 6-3/4 inches from 1/8 to 8-inches thick and has a maximum depth of cut of 1/8 inch at full width.
