Seco 17013492 Roughing End Mill 7/16 in 4 Flute Cobalt

Product Description

The SECO 17013492 is a single-end roughing end mill designed for aggressive material removal in milling applications. Built from M42 cobalt high-speed steel and finished with a TiCN coating, it handles tough ferrous and non-ferrous workpiece materials with improved heat and wear resistance. The cutter measures 7/16 inch (0.4375 inch) in diameter with a 3/8 inch shank, a 1 inch length of cut, and a 2-11/16 inch overall length. Four right-hand spiral flutes with a 30-degree maximum helix angle and chipbreaker geometry clear chips efficiently during heavy roughing passes. This tool is installed and operated by machinists and tool-and-die professionals in production and job-shop environments.

This end mill is suited for roughing operations on mill machines and machining centers where rapid stock removal is the primary objective. The TiCN coating extends tool life at elevated cutting speeds compared to uncoated cobalt tooling. The regular-length body and reduced shank diameter relative to the cutting diameter make it appropriate for standard tool holders and collets in vertical and horizontal milling setups. It is a non-centercutting design, so it is not intended for plunge cuts.

Key Features

• M42 cobalt construction for elevated heat resistance during high-feed roughing
• TiCN coating improves surface hardness and extends tool life
• 4 right-hand spiral flutes with 30-degree maximum helix angle for efficient chip evacuation
• 7/16 inch mill diameter with 3/8 inch shank — fits standard ER and straight-bore collet holders
• 1 inch length of cut and 2-11/16 inch overall length — regular-length series REM710
• Non-centercutting, right-hand cutting direction — designed for peripheral and slot roughing, not plunge entry

Compatibility

Designed as an OEM-style roughing end mill for use in standard milling machines and CNC machining centers accepting a 3/8 inch straight shank tool holder or collet.

Installation Notes

This tool is installed by machinists using appropriate collets or end mill holders rated for the 3/8 inch shank diameter. Ensure the spindle and all moving axes are fully powered down before changing tooling. Verify holder runout with a dial indicator after seating the tool, and confirm the non-centercutting design before programming any plunge moves. Follow shop-standard speeds and feeds for cobalt tooling on the specific workpiece material.
