Seco 17014100 Roughing End Mill 5/8 in 4 Flute Cobalt

Product Description

The SECO 17014100 is a single-end cobalt roughing end mill designed for aggressive material removal in milling applications. Built from M42 cobalt high-speed steel with a bright/uncoated finish, it features a 5/8 inch mill diameter, 4 spiral flutes, and a 30-degree maximum helix angle. The stub-length geometry keeps the tool rigid under heavy cuts, making it well-suited for roughing passes where tool deflection and chatter are primary concerns. Right-hand cutting and right-hand flute direction are standard on this series REM710 tool. No coolant-through ports and a non-centercutting design mean it is used for peripheral and side milling rather than plunge operations.

This end mill is used in job shop and production machining environments where cobalt tooling is preferred over carbide for its toughness and resistance to chipping under interrupted cuts or on harder workpiece materials. The stub length of cut makes it a practical choice on manual mills and CNC machining centers where setup clearance is limited. It is installed and operated by machinists and toolroom professionals working to standard milling practices.

Key Features

• 5/8 inch mill diameter with matching 5/8 inch shank diameter for direct collet or end mill holder mounting
• M42 cobalt material grade offers toughness and heat resistance beyond standard M2 HSS
• 4 spiral flutes with 30-degree maximum helix angle for efficient chip evacuation during roughing
• Stub length of cut (3/4 inch) provides maximum rigidity and minimizes deflection under heavy material removal
• Bright/uncoated finish suitable for general-purpose ferrous and non-ferrous roughing
• Right-hand cutting direction, single end configuration

Compatibility

Designed as an OEM-style roughing end mill for use in standard end mill holders, collet chucks, or Weldon shank holders accepting a 5/8 inch shank diameter on manual or CNC milling machines.

Installation Notes

This tool is installed and changed by machinists following standard machine shop lockout/tagout procedures — the spindle must be fully stopped and the machine powered down before tool changes. Shank runout and holder cleanliness directly affect tool life and surface finish; inspect the holder bore and collet before seating. Non-centercutting geometry means the tool must not be used for direct plunge entry into solid material.
