Chicago Pneumatic 7/8" x 4-1/4" Sinker Drill - CP0032A
Chicago Pneumatic CP0032A 7/8" x 4-1/4" Sinker Drill
Rock drills are ideal tools for all “hand-held” drilling operations. Their streamlined design incorporates smooth contours, a side exhaust, and a “flat-back” that makes them easy to handle in quarry, mine, drilling, and dowering work. The design also includes a higher-quality valve and cylinder-porting concept that helps maintain constant drilling speed throughout a long service life. Working parts are constantly protected with an effective lubrication system. The tool’s durable “beavertail” retainer helps deliver increased contract and reduces collar speed.
