Seco 03083983 Ball End Mill 6mm 4 Flute Carbide Altin

Product Description

The SECO 03083983 is a solid carbide ball end mill in the STB440M.2 series, designed for high-performance milling in demanding materials including stainless steel, superalloys, and titanium. With a 6.00 mm cutting diameter, 4-flute geometry, and a variable helix design, this tool supports both roughing and finishing operations in a single pass. The AlTiN (aluminum titanium nitride) PVD coating improves heat resistance and extends tool life in high-temperature cutting environments. Micrograin carbide construction provides the edge integrity needed when cutting hard materials at elevated surface speeds.

This end mill is suited for CNC machining centers in job shop and production environments where close-tolerance work on difficult-to-machine alloys is routine. The short length configuration and straight-cylindrical shank provide rigidity and minimize deflection in deep-pocket and contour milling applications. A 3.00 mm nose radius enables smooth profiling, scallop-free floor finishes, and 3D contouring on mold, die, and aerospace components. Right-hand cutting and right-hand spiral flute direction are standard for conventional and climb milling setups.

Key Features

• Variable helix flute geometry reduces chatter and harmonic vibration during aggressive cuts
• AlTiN PVD coating provides oxidation resistance and hardness for stainless steel, superalloys, and hard materials
• Micrograin solid carbide substrate maintains edge sharpness and resists micro-chipping
• 4-flute, single-end configuration supports both roughing and finishing in one tool
• 3.00 mm nose radius enables 3D profiling and smooth floor finishes
• Straight-cylindrical shank with h6 tolerance ensures consistent tool holder seating and runout control

Compatibility

Designed as an OEM-style replacement or direct-use tool for CNC milling applications requiring a 6.00 mm diameter ball end mill with a 6.00 mm straight-cylindrical shank; compatible with standard ER, hydraulic, shrink-fit, and Weldon-flat tool holders accepting 6 mm shank diameters.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Clean the tool holder bore and shank with a lint-free cloth before seating to maintain runout within specification. Verify tool projection and stick-out against the programmed depth-of-cut before initiating the first cut cycle.
