Seco 17003780 Ball End Mill 1/8 in 3 Flute Carbide Altin

Product Description

The SECO 17003780 is a solid carbide ball end mill from the SB335 series, designed for high-performance milling in demanding materials. With a 1/8 inch cutting diameter and a 3-flute spiral geometry at a 35-degree helix angle, it delivers efficient chip evacuation and smooth finishes in both roughing and finishing operations. The AlTiN PVD coating provides heat resistance and extended tool life when cutting ferrous and high-temperature alloys. A straight cylindrical shank and single-end configuration make it a direct-fit choice for CNC machining centers and manual mills running tight-tolerance work in production environments.

This end mill is rated for steel, stainless steel, superalloys, and titanium, covering ISO material groups P, M, and S. The short-length classification and 1/4 inch length of cut suit close-clearance pocketing, slotting, and contour work where rigidity matters. The 0.0625 inch nose radius and right-hand cutting and flute direction are standard for climb milling on CNC equipment. Machinists and tool-and-die professionals working in aerospace, medical, and general manufacturing will find this tool appropriate for tight-tolerance applications where coating performance and edge integrity are critical.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• AlTiN PVD coating rated for steel, stainless steel, superalloys, and titanium
• 3-flute spiral geometry with 35-degree medium helix for balanced chip flow
• 0.0625 inch ball nose radius enables precise 3D contouring and profiling
• Single-end, straight cylindrical shank for direct collet or ER chuck mounting
• Capable of both roughing and finishing cuts in a single tool

Compatibility

Part of the SECO SB335 series (catalog number SB335-0.125-D2-B.0-Z3). Designed as a replacement or production stocking item for any CNC or manual milling application requiring a 1/8 inch diameter, 3-flute solid carbide ball end mill with a 1/8 inch straight shank.

Installation Notes

Installation is performed by machinists and CNC setup technicians. Secure the shank in a properly sized collet or end mill holder, ensuring the shank is fully seated and the holder is torqued to the machine manufacturer's specification. Verify runout does not exceed the 0.0005 inch TIR maximum before beginning a cut. Inspect the cutting edges and coating for damage before each use, and replace the tool if chipping or coating breakdown is observed.
