The DELTA JT160 Shopmaster 10 Amp 6-Inch Benchtop Jointer uses a variable speed motor and two-knife cutterhead configuration with jack-screw knife leveling arrangement for easy replacement and adjustments. The 30 x 6-3/16 inch table provides support for surfacing stock up to six inches wide, including soft woods, hard woods, and plastics. The speedy 10 Amp motor spins at 6,000-11,000 RPM, which makes the dual-cutter turn at 12,000-22,000 CPM. The center-mounted fence provides ample support throughout the cut for precise edge jointing, and it tilts out at 45 degrees for added versatility.
