Dynabrade offers an updated line of 1.3-hp air tools, which are available as a right-angle sander and a right-angle depressed center wheel grinder. Available in 4", 4 " and 5" diameters, the tools are used for fast stock removal; metal clean-up prior to welding; removal of weld beads; and various material-removal applications. Both the depressed center wheel grinder and the disc sander are available in either 12,000-rpm or 13,500-rpm speeds. The grinder is designed for use with Type 27 grinding wheels, and the disc sander is for use with a variety of coated abrasives. The tools feature a governor assembly for maintaining rpm under load; a safety-lock throttle to prevent accidental start-up; a spindle lock for abrasive/wheel change; and a two-position side handle for left- or right-hand use that is said to reduce vibration to the operator’s hand. The line of air tools is also designed with a wick lubrication system, to extend gear life. Also included is a 360-degree rotational exhaust which directs the exhaust away from the operator. The depressed center wheel grinder also possesses a safety guard and wheel flange kit.
