Two models broaden high-power air drill line (February 01, 2004)

Chicago Pneumatic has added two models to its DR750 high-power air drill line. The P400 drill has a free speed of 400 rpm and a stall torque of 55 Nm (487 in.-lb). This low-speed, high-power output makes the tool useful for drilling/reaming of bit-stalling materials such as brass, copper, titanium or steel sheet and for large hole sawing of such materials as sheet glass-fibre. The P20000 high-speed model has a free speed of 20,000 rpm for working with carbon fibre composites, Kevlar and similar materials with natural lubricity. This model comes with an 8-mm (5/16-in.) keyed chuck. Stall torque is 1.6 Nm (14 in.-lb) and weight is just 1.1 kg (2.4 lb). Another addition to the line is a full range of No. 1 Jacobs taper spindle tools as an alternative to the standard 3/8-in.-24 threaded spindle.
