Seco 17014234 Roughing End Mill 1 in 5 Flute Cobalt

Product Description

The SECO 17014234 is a single-end roughing end mill designed for aggressive material removal in ferrous and non-ferrous metalworking applications. Manufactured from M42 cobalt high-speed steel, it delivers superior heat and wear resistance compared to standard HSS tooling. The mill features a 1 inch cutting diameter, a 1.5 inch length of cut, and a 0.75 inch shank diameter. With 5 spiral flutes and a right-hand cutting and flute direction, it generates a chip-breaking action that reduces chatter and allows higher feed rates during roughing passes. This tool is appropriate for machinists and tool-and-die professionals running manual or CNC milling operations.

The 17014234 is suited for roughing operations on milling machines and machining centers in production and job-shop environments. Its regular-length geometry and bright uncoated finish make it a straightforward stock replacement for general-purpose roughing on steel, stainless, and similar ferrous alloys. The 30-degree maximum helix angle balances chip evacuation with edge strength, making it effective on both horizontal and vertical mill setups. Coolant-through capability is not supported on this tool, so flood or mist coolant applied externally is the standard approach.

Key Features

• M42 cobalt construction for improved heat resistance over standard HSS
• 5 spiral flutes with chip-breaking geometry for reduced cutting forces
• Right-hand cut and right-hand flute direction for standard spindle rotation
• Bright uncoated finish suitable for general ferrous roughing
• 30-degree maximum helix angle balances chip flow and edge stability
• Single-end design in regular length for rigid setups with minimal overhang

Compatibility

Designed as an OEM-style replacement roughing end mill for standard 3/4 inch collet or end mill holders used in vertical and horizontal milling machine applications.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the spindle is fully stopped and locked before changing tooling. Secure the shank in a properly sized 3/4 inch end mill holder or collet chuck, torquing the retention hardware per the holder manufacturer's specification. Inspect the shank and holder bore for chips or damage before seating the tool.
