Seco 17003801 Ball End Mill 1/2 in 3 Flute Solid Carbide Altin

Product Description

The SECO 17003801 is a solid carbide ball end mill from the SB335 series, designed for high-performance milling in steel, stainless steel, superalloys, and titanium. With a 1/2 inch mill diameter, 3-flute configuration, and a 35-degree helix angle, this tool balances chip evacuation and surface finish in demanding cutting environments. The AlTiN PVD coating increases heat resistance and tool life, making it well-suited for dry or semi-dry machining applications. It is a single-end, right-hand cutting tool with a Weldon flat shank for positive drive retention in standard tool holders.

This end mill is built for roughing and finishing operations in ferrous and exotic alloys. Its standard length design with a 1-1/4 inch length of cut (LOC) and 3 inch overall length (OAL) fits most vertical and horizontal machining center setups. The 0.25 inch nose radius enables smooth profiling, contouring, and 3D surface milling. It is appropriate for use in CNC machining centers where tight tolerances and consistent surface quality are required across production and job-shop environments.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• AlTiN PVD coating extends tool life in high-temperature cutting of steel and superalloys
• 3-flute design with 35-degree medium helix angle balances chip flow and cutting stability
• Weldon flat shank provides secure, anti-pullout grip in standard end mill holders
• Right-hand cutting and right-hand flute direction for use with conventional CNC spindle rotation
• Rated for roughing and finishing in a single tool for Steel (P), Stainless Steel (M), and Superalloys and Titanium (S) material classifications

Compatibility

Designed for use in CNC machining centers with standard 1/2 inch end mill tool holders. Primary workpiece materials are Steel (P), Stainless Steel (M), and Superalloys and Titanium (S) per ISO material classification. Part of the SECO SB335 series. Manufacturers catalog number SB335-0.500-D3-B.3-Z3.

Installation Notes

Installation should be performed by a qualified CNC machinist or tooling technician. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the Weldon flat shank fully into the tool holder and tighten the set screw against the flat to prevent axial pullout. Verify tool runout does not exceed the maximum TIR specification before beginning a cut.
