Description

The SECO 17014078 is a single-end cobalt roughing end mill designed for aggressive material removal in milling operations. Built from M42 cobalt high-speed steel, it delivers heat and wear resistance in demanding cutting applications. The 4-flute, right-hand spiral design with a 30-degree maximum helix angle provides efficient chip evacuation and a stable cutting action. With a 3/8 inch mill diameter and 1-1/2 inch length of cut, this end mill handles slotting, profiling, and roughing passes where tool life and stock removal rate matter most. It ships with a bright, uncoated finish. Machinists and tool-and-die technicians are the primary users.

This end mill is suited for roughing operations on ferrous and non-ferrous materials in both manual and CNC milling setups. The 3/8 inch shank diameter fits standard ER collets, end mill holders, and side-lock holders common in job shop and production environments. Its regular-length geometry makes it a practical choice for general-purpose roughing where extended reach is not required. The non-centercutting design means it is intended for side milling and peripheral cuts rather than plunge entry.

Key Features

M42 cobalt steel construction for elevated heat resistance and extended tool life
4-flute right-hand spiral geometry optimized for chip clearing during roughing passes
30-degree maximum helix angle for balanced cutting forces and surface finish
Bright, uncoated finish no coating degradation risk in high-heat interrupted cuts
Regular-length flute configuration for rigid, chatter-resistant performance
Single-end design; right-hand cutting direction for standard spindle rotation

Compatibility

Designed as an OEM-style roughing end mill for use in standard 3/8 inch end mill holders, ER collet chucks, and side-lock tooling systems on vertical and horizontal milling machines.

Installation Notes

Installation should be performed by a qualified machinist following shop safety protocols. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. The shank should be seated to the recommended depth in the holder, and the setscrew or collet nut torqued to the toolholder manufacturer’s specification. Because this is a non-centercutting end mill, do not use it for direct plunge cuts into solid material.
