Parlec C40-10SM2 Shell Mill Holder CAT40 1 Inch Pilot

Product Description

The PARLEC C40-10SM2 is a CAT40 taper shank shell mill holder designed for use on vertical and horizontal machining centers. It accepts shell mill cutters with a 1 inch pilot diameter and features a 2.25 inch nose diameter with a projection of 2 inches from flange to nose end. The holder is balanced to 30,000 RPM, making it suitable for high-speed milling applications where runout control is critical. A Total Indicated Runout (TIR) of 0.0002 inches ensures tight concentricity for consistent cutter performance. The lock screw thread size is 1/2-20, compatible with the included 10LS lock screw. Installation is performed by machinists and CNC setup technicians.

This shell mill holder is used in CNC machining center setups requiring a CAT40 spindle interface. It is suited for face milling, shoulder milling, and other shell mill operations in production and job shop environments. The holder accommodates shell mill cutter cutting diameters ranging from 2.25 inches to 2.75 inches. Through-coolant is not supported on this model, so coolant delivery must be directed externally. Typical applications include ferrous and non-ferrous material removal in both roughing and finishing passes.

Key Features

• CAT40 taper shank for compatibility with standard CAT40 spindle tooling systems
• 1 inch pilot diameter for precise shell mill cutter seating
• 2 inch projection from flange to nose end for clearance in typical setups
• TIR of 0.0002 inches for tight runout control at the cutter face
• Balanced to 30,000 RPM for high-speed machining center use
• 1/2-20 lock screw thread with 10LS lock screw included

Compatibility

Designed for use with shell mill cutters in the 2.25 inch to 2.75 inch cutting diameter range on machining centers equipped with a CAT40 spindle interface.

Installation Notes

Installation is performed by a qualified machinist or CNC setup technician. The spindle must be fully powered down and the machine placed in a safe state before mounting or removing the holder. Use a calibrated torque wrench and the appropriate spanner wrench for the CAT40 retention knob; do not exceed the machine spindle manufacturer's recommended drawbar torque. Verify TIR at the pilot bore after seating to confirm proper cutter alignment before initiating a cut.
