Seco 17003792 Ball End Mill 5/16 in 3 Flute Solid Carbide

Product Description

The SECO 17003792 is a solid carbide ball end mill designed for high-performance milling in demanding metal-cutting applications. Part of the SB335 series, this stub-length single-end tool features a 5/16 inch cutting diameter, a 7/16 inch length of cut, and a 0.1563 inch nose radius. The AlTiN PVD coating provides thermal resistance and hardness retention at elevated cutting temperatures. With three right-hand spiral flutes at a 35-degree medium helix angle and a straight-cylindrical shank, this end mill is built for both roughing and finishing passes on ferrous and exotic alloys. Installation and operation are performed by machinists in CNC and manual milling environments.

This end mill is engineered for use in steel, stainless steel, superalloys, and titanium workpieces, corresponding to ISO material codes P, M, and S. The stub-length geometry and solid carbide construction make it well suited for applications requiring rigidity and precision in short-reach milling operations. The right-hand cutting direction and spiral flute configuration support efficient chip evacuation during slotting, profiling, and contouring operations on vertical or horizontal machining centers.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• AlTiN PVD coating provides oxidation resistance and extended tool life in high-temperature cutting conditions
• Three-flute design with 35-degree medium helix angle optimized for both roughing and finishing
• Stub-length geometry reduces deflection and improves dimensional accuracy in short-reach applications
• Right-hand cut and right-hand flute spiral for standard CNC milling setups
• Mill diameter tolerance of +0.0000 / -0.0020 inches and TIR maximum of 0.0005 inches for precise fitment and runout control

Compatibility

The SECO 17003792 is designed for use in standard straight-shank tool holders on CNC machining centers and manual mills. Primary workpiece materials are steel, stainless steel, superalloys, and titanium. No specific machine model compatibility was stated in the product data.

Installation Notes

This end mill is installed and operated by machinists and CNC programmers in machine shop environments. Before tool changes, the machine spindle must be fully stopped and the control placed in a safe state. The straight-cylindrical shank requires a properly sized collet or end mill holder torqued to the tool holder manufacturer specifications. Verify runout with a dial indicator after installation, given the 0.0005 inch TIR maximum specification for this tool.
