Seco 03115956 Ball End Mill 1/2 in 6 Flute Solid Carbide Altin

Product Description

The SECO 03115956 is a 6-flute solid carbide ball end mill designed for high-performance material removal in demanding machining applications. Built to Series SB638 specifications, this single-end tool features a 0.5000-inch mill diameter, a 1-1/4-inch length of cut, and a 3-inch overall length. The 38-degree medium helix promotes efficient chip evacuation, while the AlTiN PVD coating delivers elevated heat resistance and extended tool life in abrasive materials. The micrograin carbide substrate provides hardness and edge retention suited to high-feed roughing operations. Machinists and CNC operators working in job shops and production environments will find this tool well matched to their cutting demands.

This ball end mill is engineered for cutting steel, stainless steel, cast iron, superalloys, and titanium — material codes P, M, K, and S. Its variable index geometry reduces harmonic chatter during aggressive roughing passes. The straight-cylindrical 0.5000-inch shank fits standard collet and end mill holder tooling. With no coolant-through feature, this tool is suited to external flood or mist coolant setups typical in conventional and CNC milling centers.

Key Features

• 6-flute solid micrograin carbide construction for high-feed roughing and edge durability
• AlTiN PVD coating for heat and oxidation resistance in ferrous and hard materials
• 38-degree medium helix angle promotes chip flow and reduces cutting forces
• Variable index flute spacing minimizes vibration and chatter during aggressive cuts
• 0.2500-inch nose radius (ball end) for 3D contouring and profiling operations
• Right-hand cut, right-hand flute, single-end configuration — Series SB638

Compatibility

Designed for use in standard 1/2-inch collets, shrink-fit holders, or end mill holders on CNC machining centers and manual knee mills. Primary workpiece materials are steel, stainless steel, cast iron, superalloys, and titanium (ISO material codes P, M, K, S). Manufacturers catalog number SB638-0.500-D3-B.0-Z6.

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 inserting or removing the tool. Seat the shank fully to the recommended engagement depth in the holder and torque the retention mechanism per the holder manufacturer specifications. Confirm tool runout does not exceed the 0.0005-inch TIR maximum before beginning a cut.
