Seco 03115932 Square End Mill 3/16 in 6 Flute Carbide Altin

Product Description

The SECO 03115932 is a 6-flute solid carbide square end mill designed for high-performance milling in demanding metal-cutting applications. It features a 3/16 inch mill diameter, a 1/2 inch length of cut, and a 1/4 inch straight-cylindrical shank, with an overall length of 2 inches. The micrograin carbide substrate provides edge toughness and wear resistance, while the AlTiN coating improves thermal stability and extends tool life in dry or semi-dry cutting conditions. The variable helix geometry helps reduce chatter and vibration during high-speed passes. This tool is center-cutting, allowing direct plunge entry without a pre-drilled pilot hole.

This end mill is suited for finishing and semi-finishing operations in steel, stainless steel, cast iron, and hardened materials. Its long-series designation provides additional reach for deeper pockets and stepped features. The 6-flute configuration supports higher feed rates per revolution, making it a practical choice for CNC machining centers where cycle time reduction matters. It is used by machinists and tooling professionals in production and job-shop environments.

• AlTiN coating enhances heat resistance and extends tool life in ferrous materials
• Variable helix geometry reduces vibration and chatter
• Center-cutting capable — allows direct plunge milling
• Micrograin solid carbide substrate for edge strength and dimensional stability
• Right-hand cut, right-hand spiral flute configuration

Compatibility

Designed as an OEM-style replacement and production end mill for CNC milling applications requiring a 1/4 inch straight-cylindrical shank and 3/16 inch cutting diameter. Part of the SECO Series S638 long-series end mill line.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Secure the shank in a compatible end mill holder or collet chuck rated for the 1/4 inch shank diameter, ensuring proper runout before operation. Verify spindle speed and feed rate parameters against the workpiece material and machine capability before engaging the cut. Do not exceed the stated length of cut when side milling, as overextension increases deflection risk.
