Seco 03197142 Shell Mill Holder CAT50 0.75 in Pilot

Product Description

The SECO 03197142 is a CAT50 taper shank shell mill holder designed for secure, precise face milling operations on machining centers. It accepts shell mills through a 0.75 inch pilot diameter and features a 1.75 inch nose diameter flange interface. The holder measures 6.68 inches in overall length, with a 3.50 inch projection from flange to nose end. Through-coolant capability allows cutting fluid to be directed directly to the cutting zone, extending tool life and improving chip evacuation. Weighing 7.94 pounds, this holder is built for rigid, high-torque milling applications. Installation is performed by qualified machinists or toolroom personnel.

This shell mill holder is suited for use on vertical and horizontal machining centers equipped with CAT50 spindle interfaces. Typical applications include roughing and finishing passes on large workpieces in production and job-shop environments. The through-coolant feature makes it particularly effective in deep-pocket milling and high-feed operations where heat and chip buildup are concerns. It is used in aerospace, die and mold, heavy equipment, and general metalworking industries.

Installation Notes

Shell mill holders must be installed and removed by qualified machinists or toolroom technicians. Always power down and lock out the machining center spindle before changing toolholders. Use a calibrated torque wrench and the correct retention knob specification for your machine spindle when securing the holder. Inspect the taper shank and spindle bore for nicks, burrs, or contamination before seating the holder.
