1-1/2" Round Drill Tool Holder Assembly

The round shank tool holder is used for operations such as center drilling, drilling, tapping, reaming, or bar stock pulling.

The tool holder is available with bore sizes of 1-1/2" and 40 mm. For optimum rigidity, HDC-12 or HDZ-12 solid bushings are used in the CL-21 holder to grip round shank tools up to 1-1/4" or #4MT tooling. The SG-180 Double-Angle Collet Tool Holder is also available to rigidly grip tools from 3/64" to 3/4" (3.5 mm to 19.0 mm) in diameter. HDC-12M and HDZ-12M solid bushings are used in the CL-20 M holder to grip round shank size tools up to 32 mm or #3 and #4 MT tooling. 

Two coolant balls in the holders direct coolant to the tooltip while machining. A 1/8-27 pipe plug, which is included, threads into the right coolant ball for through-the-tool coolant flow  (a cover plate is included with each holder for through-the-tool coolant capabilities). To restrict coolant flow, a pipe plug is threaded into both coolant balls.
