Seco 03197130 Shell Mill Holder CAT40 0.75 in Pilot

Product Description

The SECO 03197130 is a CAT40 taper shank shell mill holder designed for use in CNC machining centers. It accepts shell mills via a 0.75 inch pilot diameter and features a 1.75 inch nose diameter with a flange-to-nose projection of 4.0 inches. Through-coolant capability allows direct delivery of cutting fluid to the tool tip, supporting higher feed rates and extended tool life in demanding milling operations. Licensed machinists and CNC toolroom technicians install this holder as part of a modular tooling setup. At 7.369 inches overall length and 3.97 pounds, it is sized for standard CAT40 spindle configurations.

This shell mill holder is suited for horizontal and vertical machining centers equipped with CAT40 spindle interfaces. It is commonly used in production milling environments where face milling, shoulder milling, or slot milling operations require a rigid, balanced toolholder with through-coolant support. The 4.0 inch flange-to-nose projection provides clearance in setups where reach is a factor, making it a practical choice for both prototype and production runs.

Key Features

• CAT40 taper shank for compatibility with standard CAT40 spindle interfaces
• 0.75 inch pilot diameter for positive shell mill registration and drive
• 1.75 inch nose diameter provides a robust clamping surface
• Through-coolant design delivers coolant directly to the cutting zone
• 4.0 inch flange-to-nose projection for extended reach applications
• 7.369 inch overall length suits a wide range of machining center setups

Compatibility

Designed as an OEM-style shell mill holder for machining centers with a CAT40 taper spindle interface.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician familiar with CNC toolholder assembly procedures. The spindle must be fully stopped and the machine placed in a safe state before mounting or removing the holder. Use the appropriate spanner wrench and retention knob torqued per the machining center manufacturer's specifications. Verify through-coolant port alignment with the machine spindle coolant supply before beginning any cutting operation.
