Parlec C50-10SM2 Shell Mill Holder CAT50 1 Inch Pilot

Product Description

The PARLEC C50-10SM2 is a CAT50 taper shank shell mill holder designed for milling operations on machining centers that accept CAT50 tooling. It features a 1 inch pilot diameter and a 2.25 inch nose diameter, with a projection from flange to nose end of 2 inches. The holder accommodates shell mills with cutting diameter ranges from 2.25 inches to 2.75 inches and is balanced to 30,000 RPM, making it suitable for high-speed machining applications. Installation requires a 1/2-20 lock screw thread, and the included lock screw designation is 10LS. This holder is intended for use by machinists and toolroom professionals in production and job shop environments.

The C50-10SM2 is used in vertical and horizontal machining centers equipped with CAT50 spindles. It is well suited for face milling, shoulder milling, and other shell mill operations where a rigid, precise toolholder is required. The TIR of 0.0002 inches supports tight tolerancing in finish milling passes. This holder does not feature through-coolant capability, so flood or mist coolant delivery is handled externally.

Installation Notes

Shell mill holders should be installed and removed by a qualified machinist following the machine tool manufacturer's spindle interface procedures. Ensure the spindle and drawbar are fully disengaged and the machine is powered down before tool changes. Verify that the shell mill bore matches the 1 inch pilot diameter and that the lock screw is torqued per the shell mill manufacturer's specification. Inspect the taper shank and spindle taper for chips or contamination before seating the holder.
