With the AC-25 pneumatic collet closer, collets can be clamped and unclamped with the flip of a lever.

The AC-25 is our smallest and most economical closer. It fits entirely inside the HA5C body, and can be used vertically or horizontally. Since the AC-25 utilizes air pressure to close, part clamping pressure can be varied easily by regulating the applied air pressure. The AC-25 provides medium holding power of up to 3000 lb (13,345 N) of draw force, with 0.030" (0.76 mm) of travel, and is recommended for drilling and light milling of collet-size parts. Includes one closer for each head on multi-head units.
