Seco 17014086 Roughing End Mill 1/2 in 4 Flute Cobalt

Product Description

The SECO 17014086 is a single-end roughing end mill designed for aggressive material removal in milling operations. Built from M42 cobalt high-speed steel with a bright, uncoated finish, it measures 0.5 inches in diameter with a 1.0 inch length of cut and a 3.0 inch overall length. The 4-flute, right-hand spiral configuration with a 30-degree maximum helix angle drives efficient chip evacuation during heavy roughing passes. This is a stub-length tool intended for machinists and tool-and-die professionals running knee mills, vertical machining centers, or CNC milling equipment where rigidity and stock removal rate matter most.

This end mill is suited for roughing applications in ferrous and non-ferrous materials where cobalt tooling is specified over carbide for its toughness and resistance to shock loading. Typical use cases include roughing slots, profiling, and pocketing on manual or CNC milling machines in job shop, maintenance, and production environments. The stub-length design minimizes deflection in setups with shorter tool-to-spindle overhangs. Non-centercutting geometry means this tool is not intended for plunge cutting and should be ramped or side-loaded into cuts.

Key Features

• M42 cobalt HSS construction provides toughness and heat resistance for roughing cuts
• 4-flute right-hand spiral design promotes efficient chip removal and surface contact
• 30-degree maximum helix angle balances cutting efficiency with edge strength
• Stub-length body reduces deflection during heavy material removal
• Bright, uncoated finish suitable for a wide range of ferrous materials
• Non-centercutting, single-end design; ramp or side-load entry required

Compatibility

Designed as an OEM-style single-end roughing end mill compatible with standard 1/2 inch milling machine collets and end mill holders accepting a 0.5000 inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Secure the shank fully within the collet or end mill holder to the manufacturer-recommended engagement depth, and verify runout with a dial indicator before cutting. Do not use this tool for plunge entry; use ramp-in or helical interpolation strategies instead.
