Seco 17004827 Ball End Mill 1/16 in 2 Flute Solid Carbide

Product Description

The SECO 17004827 is a solid carbide ball end mill engineered for precision milling in steel and hardened materials. Part of the MBZ215 series, this single-end tool features a 1/16 inch (0.0625 inch) mill diameter with a matching 1/16 inch length of cut and a low 15-degree helix angle optimized for stability in difficult-to-machine workpieces. An AlTiN PVD coating delivers heat resistance and wear protection during high-speed cutting operations. The extended reach design and 1/16 inch neck length allow access to deep pockets and tight geometries. With centercutting capability and right-hand flute and cutting direction, this tool handles both roughing and finishing passes in a single setup. It is sized for use in CNC machining centers and high-precision manual mills.

This end mill is suited for mold and die work, aerospace component machining, and precision part manufacturing where small-diameter profiling, contouring, and slot milling in steel or hardened materials is required. The 1/4 inch straight-cylindrical shank provides secure clamping in standard collet chucks and end mill holders. The extended reach design makes it well suited for deep-cavity work where standard-length tooling cannot reach the workpiece surface. It is appropriate for both job shops and production environments running ferrous alloys and hardened steels.

Key Features

• 1/16 inch ball nose diameter with 0.0313 inch nose radius for fine contouring and profiling
• AlTiN PVD coating for elevated heat resistance in steel and hardened material cutting
• Low 15-degree helix angle reduces cutting forces in hard and difficult materials
• Extended reach with 1/8 inch reach length and 1/16 inch neck length for deep-pocket access
• Centercutting geometry supports plunge and ramp entry
• Solid carbide construction provides rigidity and dimensional stability at small diameters
• Suitable for roughing and finishing operations in a single tool

Compatibility

Designed for use in steel and hardened materials (ISO material codes P and H). Compatible with standard 1/4 inch collet chucks and end mill holders on CNC machining centers and precision milling machines. Part of the SECO MBZ215 series (catalog number MBZ215-0.063-G1-B.0-Z2).

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the machine fully powered down and the spindle locked. Ensure the 1/4 inch straight shank is fully seated and properly torqued in the collet or holder per the toolholder manufacturer specifications. Verify runout against the listed TIR maximum of 0.0005 inch before beginning the cut cycle. At small diameters, excessive overhang or side load can cause tool deflection or breakage, so follow programmed feed and speed parameters appropriate for the workpiece material and depth of cut.
