Parlec C50-10SM6 Shell Mill Holder CAT50 1 Inch Pilot

Product Description

The PARLEC C50-10SM6 is a CAT50 taper shank shell mill holder designed for use on CNC machining centers. It accepts shell mills with a 1-inch pilot diameter and features a 2.25-inch nose diameter with a 6-inch projection from flange to nose end. The lock screw thread size is 1/2-20, using lock screw 10LS. This holder is balanced to 30,000 RPM and maintains a TIR of 0.0002 inches, making it suitable for high-speed, precision face milling operations. Machinists and CNC operators install this holder as a direct-mount interface between the machine spindle and the shell mill cutter.

The C50-10SM6 is used on CAT50-spindle CNC mills and machining centers in metalworking environments, both job shop and production. The 6-inch projection makes it practical for setups that require extended reach from the spindle face. It accommodates shell mill cutting diameters ranging from 2.25 inches to 2.75 inches. Through-coolant is not supported on this holder. Typical applications include face milling, shoulder milling, and surface finishing operations on ferrous and non-ferrous materials.
