Specifically designed for aluminum, mild steel - high interference applications
Class I. Used in production and rework applications with aluminum and mild steel, it is commonly specified for aircraft service bulletins, and is available in standard sizes ranging from 1/8" through 1 51/64" (3.1—45.6 mm) in 1/64" increments. Provided applied expansion ranges from 3-6% (4% nominal—high interference). See Section V for tooling tables. CB tooling is available in tooling kits, CWORK-1 and CWORK3.
