Seco 17003782 Ball End Mill 5/32 in 3 Flute Solid Carbide

Product Description

The SECO 17003782 is a solid carbide ball end mill designed for high-performance milling in demanding materials including steel, stainless steel, superalloys, and titanium. Part of the SB335 series, it features a 5/32-inch (0.1563-inch) mill diameter, a 3-flute spiral configuration, and a 35-degree medium helix angle. The AlTiN PVD coating improves heat resistance and tool life at elevated cutting temperatures. At 2 inches overall length with a 5/16-inch length of cut, this is a short-length, single-end geometry suited for precision profiling and contouring work in tight setups.

This end mill is intended for use in CNC machining centers and manual milling applications where close-tolerance profiling, slotting, or finishing passes are required on ferrous and high-strength alloy workpieces. The 3/16-inch straight-cylindrical shank fits standard collet chucks and ER-style toolholding systems. It is sized for short-reach applications and handles both roughing and finishing material removal in a single tool. Machinists and tool-and-die shops working with P-, M-, and S-class workpiece materials will find this geometry appropriate for those cutting conditions.

Key Features

• Solid carbide construction provides rigidity and wear resistance in hard and abrasive materials
• AlTiN PVD coating extends tool life by reducing heat buildup at the cutting edge
• 3-flute spiral design supports both roughing and finishing passes in a single tool
• 35-degree medium helix angle improves chip evacuation and surface finish on steel and superalloys
• Right-hand cut and right-hand flute direction for use in standard CNC and manual milling spindles
• Mill diameter tolerance of plus 0.0000 / minus 0.0020 inches supports close-tolerance profiling work

Compatibility

Designed for use with steel, stainless steel, superalloys, and titanium workpiece materials (ISO material codes P, M, and S). Fits standard 3/16-inch collet and toolholder systems. Part of the SECO SB335 series; catalog number SB335-0.156-F2-B.0-Z3.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully stopped and the machine in a safe, locked-out state. Ensure the 3/16-inch straight-cylindrical shank is fully seated and properly torqued in the collet or toolholder before initiating any cut. Verify runout does not exceed the maximum TIR of 0.0005 inches after mounting to maintain dimensional accuracy and tool life. Always confirm cutting parameters against the workpiece material class before engaging the tool.
