Parlec C40-75SM200 Shell Mill Holder CAT40 0.75 in Pilot

Product Description

The PARLEC C40-75SM200 is a CAT40 taper shank shell mill holder designed for secure face milling operations on CNC machining centers. It features a 0.75 inch pilot diameter and a 1.75 inch nose diameter, providing a rigid, concentric interface between the spindle and shell mill cutter. The holder includes through-spindle coolant delivery, directing coolant directly to the cutting zone for improved chip evacuation and tool life. Total indicator runout (TIR) is held to 0.0002 inches, making it suitable for finish milling applications where dimensional accuracy is critical. Licensed machinists and CNC setup technicians install this holder in production and job-shop environments.

The C40-75SM200 is suited for horizontal and vertical machining centers equipped with a CAT40 spindle interface. Its 4.69 inch overall length and 2.00 inch projection from flange to nose end position the cutter at a standard gauge distance for typical face milling setups. The through-spindle coolant configuration requires a coolant-through spindle on the host machine. It is balanced for operation up to 20,000 RPM, supporting high-speed machining strategies on capable equipment.

Key Features

• CAT40 taper shank for direct mounting in CAT40-compatible machining center spindles
• 0.75 inch pilot diameter with 1.75 inch nose diameter for standard shell mill fitment
• Through-spindle coolant delivery for direct coolant flow to the cutting zone
• TIR of 0.0002 inches for precise, low-runout cutter positioning
• Balanced to 20,000 RPM for compatibility with high-speed spindle applications
• 2.00 inch flange-to-nose projection for standard gauge-length setups

Compatibility

Designed as an OEM-style shell mill holder for machining centers with a CAT40 spindle taper and through-spindle coolant capability, accepting shell mills with a 0.75 inch pilot bore.

Installation Notes

Installation should be performed by a qualified CNC machinist or setup technician. Power down and lock out the machining center spindle before mounting or removing the holder. Use a calibrated torque wrench and the appropriate retention knob or drawbar specification required by the host machine manufacturer. Verify runout at the nose after installation using a dial test indicator before cutting.
