Product Description

The SECO 17002378 is a 9-flute solid carbide corner radius end mill designed for high-performance milling in demanding material applications. It carries a 1-inch cutting diameter, a 3.25-inch length of cut, and a 0.030-inch corner radius, making it suitable for both roughing and finishing passes. The AlTiN PVD coating delivers high heat and wear resistance, which is critical when cutting steel, stainless steel, cast iron, and superalloys including titanium. The micrograin carbide substrate and super-close pitch flute geometry help maintain rigidity and surface finish quality across extended cuts. Machinists and tooling technicians in production and job-shop environments rely on this series for consistent tool life in difficult-to-machine workpieces.

The SECO 17002378 belongs to the S938R series and is built for use in CNC machining centers with standard toolholders accepting a 1-inch straight cylindrical shank. It handles a wide range of ferrous and exotic materials, including P-class steels, M-class stainless steels, K-class cast iron, and S-class superalloys and titanium. The single-end, right-hand cutting configuration with a medium 38-degree helix suits both peripheral and slotting operations where chip evacuation and tool stability are priorities. This end mill is appropriate for horizontal and vertical machining centers running high-speed steel or carbide-compatible toolpaths.

Key Features

9-flute super-close pitch design supports aggressive material removal rates while maintaining surface finish
AlTiN PVD coating provides elevated temperature resistance for steel, stainless, cast iron, and superalloy cutting
0.030-inch corner radius reduces stress concentration at the cutting edge and extends tool life
Micrograin solid carbide substrate delivers rigidity and edge sharpness for precise dimensional control
38-degree medium helix promotes efficient chip flow and reduces cutting forces in tough materials
Right-hand flute direction and single-end configuration for standard CNC toolholder mounting

Compatibility

Designed for use with standard CNC toolholders accepting a 1-inch straight cylindrical shank. Primary workpiece materials include steel, stainless steel, cast iron, and superalloys and titanium (material codes P, M, K, S). Part of the SECO S938R series.

Installation Notes

Installation and tool changes should be performed by a qualified machinist or tooling technician with the machine spindle fully stopped and locked out per facility lockout/tagout procedures. Seat the shank fully in the toolholder collet or chuck and verify runout does not exceed the TIR maximum of 0.0005 inches before beginning a cut. Do not use this end mill in center-cutting applications, as it is not center-cutting. Confirm toolholder compatibility and clamping torque requirements per the toolholder manufacturer specifications before use.
