Chicago Pneumatic expanded its CP3550 series of grinders and sanders, which are for high-output work environments like foundries, casting plants, fabrication shops and shipyards. The new tools include: a 6-in. angle grinder; two standard and two extended die grinders that come complete with an Erickson 200 collet for attachments of 1/4- in. and 6-mm mounted points and carbide burrs; two new tools for use with 7-in. abrasive pads; and a low-speed sander with a gearbox that generates high torque with reduced speed (3,000 rpm) for polishing or delicate applications.
