Description

The SECO 17014202 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, this tool delivers durability and heat resistance in demanding cutting environments. It features a 1/2 inch mill diameter, 4 spiral flutes, and a right-hand cutting and flute direction. The 30-degree maximum helix angle promotes efficient chip evacuation during roughing passes. With a 3 inch length of cut and 5 inch overall length, it is suited for regular-length reach applications. This end mill is installed and used by machinists and CNC operators working in job shops, production facilities, and tool rooms.

The 17014202 is intended for roughing operations where stock removal rate takes priority over surface finish. The chipbreaker-free, non-centercutting design is optimized for peripheral cutting rather than plunge operations. Its 1/2 inch shank diameter fits standard end mill holders and collet chucks common in vertical machining centers and manual knee mills. The cobalt M42 substrate makes it a practical choice for cutting alloy steels, stainless steels, and other tough ferrous materials that generate significant heat at the cutting edge.

Key Features

M42 cobalt construction for heat resistance and toughness in ferrous materials
4 spiral flutes with right-hand cutting and flute direction for efficient chip flow
30-degree maximum helix angle promotes chip evacuation during heavy roughing passes
1/2 inch mill diameter and 1/2 inch shank diameter for compatibility with standard toolholders
3 inch length of cut in a regular-length configuration for stable reach
Bright/uncoated finish, no coolant-through requirement, suitable for flood or dry cutting setups

Compatibility

Designed as an OEM-style roughing end mill for use in standard 1/2 inch end mill holders and collet systems on vertical machining centers, CNC mills, and manual milling machines.

Installation Notes

Installation is performed by machinists using a calibrated torque wrench and the appropriate end mill holder or collet chuck. Ensure the spindle is powered off and locked before inserting or removing the tool. Confirm shank engagement depth meets the toolholder manufacturer minimum before tightening. Verify runout with a dial indicator after seating to reduce premature tool wear.
