CAC (Converter Accessory Corporation) adds a new chuck to its line of COR-LOK air and mechanical chucks. The COR-LOK-XE pneumatic chucks feature a tubing (bladderless) design, contoured to match the geometry of the spiraled shaft body. The contoured tubing allows exceptional, even gripping torque across the full length of the chuck, a long tubing life and easy replacement. To inflate, they only require 70 PSI and can handle up to 120 PSI. The COR-LOK-XE model air chuck utilizes a pneumatically expanding, spirally wrapped external element to engage the core.
