Seco 17012969 Ball End Mill 1in 4 Flute Cobalt Ticn SPB540

Product Description

The SECO 17012969 is a single-end ball end mill from the SPB540 series, designed for finishing operations in demanding metal-removal applications. It features a 1-inch mill diameter with a 0.5-inch nose radius, a 3-inch length of cut, and a 5.5-inch overall length. The 4-flute cobalt construction is paired with a Physical Vapor Deposition (PVD) TiCN coating, which increases surface hardness and reduces friction during cutting. The 30-degree medium helix angle and right-hand spiral flutes promote efficient chip evacuation. This tool is intended for use by machinists and toolroom professionals working on CNC mills and manual milling machines.

The 17012969 is suited for finishing passes on steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium — covering ISO material groups P, M, K, N, and S. The Weldon flat shank provides a secure, positive drive connection in standard end mill holders. The SPB540 series is a standard-length design with no extended reach and no coolant-through capability, making it appropriate for open-pocket, contour, and 3D surface finishing work where a controlled depth of cut and tight tolerances are required.

Key Features

• 1-inch mill diameter with 0.5-inch nose radius for full ball-end contour cutting
• 4-flute cobalt construction for increased tool life in ferrous and difficult-to-machine materials
• TiCN PVD coating reduces friction and extends wear resistance in steel and stainless applications
• 30-degree medium helix angle with right-hand spiral flutes for efficient chip evacuation
• Weldon flat shank ensures positive drive and minimizes tool pullout in standard holders
• Finishing geometry optimized for 3D surface work, contour milling, and pocket finishing

Compatibility

Designed as a standard-fitment replacement or direct selection for CNC and manual milling setups requiring a 1-inch shank, single-end ball nose end mill in the SPB540 series. Compatible with ISO material groups P (Steel), M (Stainless Steel), K (Cast Iron), N (Non-Ferrous Metal), and S (Superalloys and Titanium).

Installation Notes

Install into a compatible end mill holder or Weldon-style collet chuck rated for the 1-inch shank diameter, and verify that the Weldon flat is properly engaged by the set screw before operation. Confirm spindle speed and feed rate parameters against the SECO SPB540 series cutting data recommendations for the specific workpiece material before starting a cut. Inspect the tool holder bore and retention hardware for wear or contamination prior to mounting. Always bring the machine spindle to a complete stop and lock it out before changing tooling.
