Seco 03083833 Ball End Mill 0.5 in 4 Flute Carbide Altin

Product Description

The SECO 03083833 is a solid carbide ball end mill designed for high-performance milling in demanding materials including stainless steel, high-temperature alloys, and hardened materials. Part of the STB440.2 series, it features a 0.5 inch mill diameter, a 1 inch length of cut, and a 4-flute configuration with a variable helix angle of 40 degrees. The AlTiN PVD coating provides thermal resistance and extended tool life in aggressive cutting conditions. With a right-hand cutting direction, spiral flute geometry, and centercutting capability, this end mill handles both roughing and finishing operations in a single tool. It is suited for use by machinists and CNC tool-and-die professionals in precision machining environments.

This end mill is built for applications in aerospace, mold-and-die, and precision manufacturing where stainless steel and high-temp alloys are common workpiece materials. The short length type and 0.5 inch Weldon flat shank provide rigidity and secure tool holding in standard end mill holders. The single-end configuration and 3 inch overall length make it appropriate for typical vertical machining center setups requiring tight tolerances and consistent surface finishes.

Key Features

• 0.5 inch mill diameter with 0.25 inch nose radius for true ball end geometry
• 4-flute spiral configuration with variable helix for reduced chatter and improved chip evacuation
• AlTiN PVD coating rated for stainless steel, high-temp alloys, and hardened materials
• Centercutting design allows plunge entry into workpiece material
• Weldon flat shank for positive drive and reduced pullout risk
• Micrograin solid carbide substrate for rigidity and wear resistance

Compatibility

Designed for use in standard 0.5 inch end mill holders and collet chucks. Rated for milling stainless steel (ISO M), high-temperature alloys (ISO S), and hardened materials (ISO H) as specified by the manufacturer. Series STB440.2, catalog number STB440.2-0.500-D2-B.3-Z4.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully stopped and machine in a safe, locked-out state. Verify shank-to-holder fit and torque set screws to the holder manufacturer's specification using the appropriate hex key. Confirm runout does not exceed the maximum TIR of 0.0005 inches before beginning a cut. Follow your machine tool builder's guidelines for feeds, speeds, and depth of cut when working with hardened or high-temp alloy workpieces.
