Seco 03197147 Shell Mill Holder CAT50 1 Inch Pilot

Product Description

The SECO 03197147 is a CAT50 taper shank shell mill holder designed for use in CNC machining centers that require secure, high-rigidity mounting of shell mill cutters. The holder features a 1 inch pilot diameter and a 2.25 inch nose diameter, with an overall length of 8.68 inches and a projection from flange to nose end of 6 inches. Through-coolant capability allows coolant delivery directly to the cutting zone, supporting extended tool life and chip evacuation during heavy milling operations. This holder is intended for installation by machinists and toolroom professionals in production and job-shop environments.

This shell mill holder is suited for horizontal and vertical machining centers equipped with CAT50 spindle interfaces. It is commonly used in applications requiring large-diameter face milling, shoulder milling, or surface milling on ferrous and non-ferrous materials. The CAT50 taper provides the pulling force and rigidity needed for aggressive cuts at high spindle speeds. At 11.68 pounds, the holder is built for heavy-duty milling duty cycles in both production and prototype environments.

Key Features

• CAT50 taper shank for compatibility with standard CAT50 spindle interfaces on CNC machining centers
• 1 inch pilot diameter for precise shell mill cutter registration
• 2.25 inch nose diameter provides a broad seating surface for shell mill bodies
• Through-coolant design directs coolant to the cutting zone for improved tool life and chip removal
• 6 inch projection from flange to nose end accommodates fixtures requiring extended reach
• Overall length of 8.68 inches suits a range of standard machine table clearances

Compatibility

Designed as an OEM-style shell mill holder for CNC machining centers equipped with a CAT50 taper spindle interface and shell mill cutters with a 1 inch pilot bore.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician using a CAT50-compatible tool holder tightening fixture and the appropriate retention knob for the machine spindle. Power down and lock out the machining center before mounting or removing the holder from the spindle. Inspect the taper bore and holder shank for nicks, chips, or contamination before seating; clean contact surfaces thoroughly to ensure full taper engagement. Verify retention knob torque to the machine spindle manufacturer specification before operation.
