BIG KAISER PRECISION TOOLING LTD.: The Tool Pro is a unique tool holding device for the assembly and disassembly of tooling systems. Depressing the large gold button permits the adapter to rotate 360º and lock in 45º increments, allowing convenient access for all operations in one setup. Tightening torque for tool clamping can be applied in a downward motion allowing the Tool Pro to be installed on tool carts. Tools are simply lowered into the tool pot and automatically clamped into place with a spring-loaded pin that locates precisely into the tool holder. With the Tool Pro, you reduce damage to your expensive tool holders, shanks and machine spindles while providing a safe working environment for tool assembly operators.
