Seco 03115946 Ball End Mill 3/8 in 6 Flute Solid Carbide

Product Description

The SECO 03115946 is a 6-flute solid carbide ball end mill from the SB638 series, designed for high-performance milling in demanding materials. It features a 3/8 inch cutting diameter, a 3/8 inch length of cut, and a 38-degree helix angle with AlTiN coating applied via PVD process. The micrograin carbide substrate and AlTiN finish deliver thermal resistance and hardness retention at elevated cutting temperatures. Variable index geometry reduces chatter and improves surface finish. This tool is suited for machinists and CNC operators running steel, stainless steel, cast iron, and high-temperature alloys.

The 03115946 is configured as a single-end, right-hand cutting, right-hand flute tool with a straight cylindrical shank and stub-length profile. It is intended for roughing operations in ferrous and exotic alloy materials. The 2 inch overall length and compact stub geometry make it well suited for applications requiring rigidity with limited stick-out. It fits standard 3/8 inch tool holders and collet chucks common in CNC machining centers.

Key Features

• 6-flute design increases feed rate capability and material removal in roughing operations
• AlTiN coating (PVD process) provides high heat resistance for dry and semi-dry cutting in hard materials
• 38-degree medium helix angle balances chip evacuation and cutting force
• Variable index flute spacing reduces harmonic vibration and chatter
• Micrograin solid carbide substrate maintains edge integrity in steel, stainless steel, cast iron, and high-temp alloys
• Center-cutting capable; right-hand cut and flute direction

Compatibility

Designed for use in steel (P), stainless steel (M), cast iron (K), and high-temperature alloys (S) per ISO material codes. Fits standard 3/8 inch diameter collet chucks and tool holders. Part of the SECO SB638 series; catalog reference SB638-0.375-D1-B.0-Z6.

Installation Notes

Installation and operation should be performed by qualified machinists familiar with CNC tooling setup and safe cutting practices. Ensure the spindle is fully stopped and the machine is in a safe state before loading or unloading the tool. Verify runout does not exceed the specified TIR maximum of 0.0005 inches using a dial indicator at setup. Follow the machine manufacturer and tooling guidelines for appropriate speeds, feeds, and clamping torque for 3/8 inch carbide end mills.
