Professional Tool Manufacturing

Professional Tool Manufacturing of Ashland, Ore., released its latest Work Sharp WS3000 sharpener for chisels, plane irons, and other wood carving and lathing tools.

The air-cooled, dry sharpener combines a 1/5 hp induction motor, a bevel angle sharpening port, and various 6-in pressure-sensitive-adhesive abrasives for greater precision.

The 6 in. by 3/8 in. tempered glass wheels provide a flat, stable surface for the PSA abrasives. A maintenance-free timing belt allows a gear-reduced maximum wheel speed of 580 rpm. And a port heat sink and routed air flow prevent overheating during sharpening.

The unit’s housing is formed sheet metal, with cast metal for the top and impact-and vibration-resistant plastic for the base.

Charles Machine Works

Charles Machine Works of Perry, Okla., has introduced its biggest trencher ever in the new Ditch Witch HT220.

Built to dig through rock in extreme conditions, the hydrostatic HT220 uses 200 hp to cut trenches up to 8 ft deep and 24 in wide. The flywheel gearbox delivers full power to the trenching arm on demand, while minimizing shockloads to the unit’s hydraulic system.

The new trencher features cruise control to automatically adjust ground speed for changing soil conditions and a bit block system that allows the user to customize digging-tooth patterns. It also has a stabilizer to isolate vibration in harsh conditions and a reversible spoils conveyor to deposit soils on either side of a trench. The unit’s headshaft is made of forged, heat-treated, high-alloy steel.

The new trencher features user comforts such as easy-to-navigate controls, a fully enclosed cab with climate control, and a sturdy undercarriage providing support over rocky terrain.

The company’s engines had previously been rated to safely handle B5 blends. Cummins has since completed extensive testing and evaluation of its equipment – and developed usage guidance specifications – to ensure proper operation of its engines with B20 blends. The specification for the I-class engines applies to models built in 2002 or later.
