4455 22” Planer

The Oliver 4455 22” Planer puts other planers to shame. With a super wide capacity, it’ll handle stock up to 22” wide, and take up to 3/16” off in a single pass. But volume isn’t everything, this Oliver outputs stock that’s smooth and straight. A sectional infeed roller and chip breaker apply uniform pressure on uneven stock, coupled with a driven outfeed roller to keep your stock moving smoothly. Add 2 feed speeds for extra quality, a digital thickness scale for quick reference and a powerful 7.5 or 10HP motor, and you’ve got a planer that’s ready to tackle the toughest tasks!
