Parlec C50-15SM6 Shell Mill Holder CAT50 1.5 Inch Pilot

Product Description

The PARLEC C50-15SM6 is a CAT50 taper shank shell mill holder designed for use in CNC machining centers requiring a secure, accurate interface between the spindle and face mill or shell mill cutter. The holder features a 1.5 inch pilot diameter and a 3.75 inch nose diameter, with a flange-to-nose projection of 6 inches. A total indicator runout (TIR) of 0.0002 inches ensures precise cutter alignment, making it suitable for high-accuracy milling operations. It accepts shell mill cutters in the 4 to 5 inch cutting diameter range and is balanced to 30,000 RPM for use in high-speed machining applications.

This shell mill holder is intended for metalworking and machining environments where a CAT50 spindle interface is present. Typical installations include horizontal and vertical CNC machining centers in job shops, production floors, and aerospace or industrial manufacturing facilities. The 3/4-16 lock screw thread (lock screw model 15LS) secures the cutter in place during heavy face milling passes. Machinists and tooling specialists are the primary installers of this holder.

Key Features

• CAT50 taper shank for compatibility with standard CAT50 spindle interfaces

• 6 inch flange-to-nose projection for reach in deep setups
• TIR of 0.0002 inches for high-accuracy cutter runout control
• Balanced to 30,000 RPM for high-speed machining applications
• 3/4-16 lock screw thread secures shell mill cutter body

Compatibility

Designed for use with shell mill and face mill cutters in the 4 to 5 inch cutting diameter range mounted on CAT50 taper spindle machining centers. Accepts lock screw model 15LS with a 3/4-16 thread.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. The spindle must be fully powered down and the machine placed in a safe, locked-out state before mounting or removing any toolholder. Clean the CAT50 taper and spindle bore thoroughly before seating the holder to ensure full contact and minimize runout. Torque the retention knob and lock screw according to the machining center manufacturer specifications.
