Seco 17014844 Roughing End Mill 3/4 in 4 Flute Cobalt Tialn

Product Description

The SECO 17014844 is a single-end roughing end mill designed for aggressive material removal in milling operations. Built from M42 cobalt high-speed steel with a TiAlN coating, it handles heat and wear generated during heavy roughing passes. The 3/4 inch diameter cutting head features 4 spiral flutes with a right-hand cutting and flute direction, and a 30-degree maximum helix angle. With a 2.5 inch length of cut and 4.75 inch overall length, this tool is suited for full-slot and peripheral roughing in metalworking environments. Machinists and tool-and-die professionals will recognize this as a standard workhorse for production roughing applications.

The 17014844 is designed for roughing operations on ferrous and non-ferrous metals where rapid stock removal is the priority before a finishing pass. The TiAlN coating improves thermal resistance, making it effective at elevated cutting speeds. It is not center-cutting, so plunge entries are not supported. The 3/4 inch shank diameter matches the cutter diameter, allowing it to seat directly in standard end mill holders or collet chucks. This is a regular-length tool appropriate for setups with standard spindle-to-work clearance.

Key Features

• M42 cobalt construction provides superior heat and wear resistance over standard M2 HSS
• TiAlN coating extends tool life at higher cutting speeds and temperatures
• 4 right-hand spiral flutes at 30-degree maximum helix angle for efficient chip evacuation
• 2.5 inch length of cut with 4.75 inch overall length in a regular-length configuration
• Single-end design with 3/4 inch shank diameter for direct collet or end mill holder mounting
• Non-center-cutting geometry suited for peripheral and slot milling, not plunge entry

Compatibility

Designed as an OEM-style roughing end mill for use in standard 3/4 inch end mill holders, collet chucks, and milling machine spindles accepting 3/4 inch shank tooling. Part of the SECO REM445 series.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the machine spindle is fully powered down and the tool holder is clean and free of chips before seating the end mill. Shank insertion depth should meet the holder manufacturer minimum engagement specification. Verify runout with a dial indicator after tightening to confirm proper seating before beginning a cut.
