Description
The SECO 17003785 is a 3-flute solid carbide ball end mill from the SB335 series, designed for precise contour milling and finishing passes in steel, cast iron, aluminum, and other non-ferrous materials. The tool measures 3/16 inch (0.1875 inch) in diameter with a 9/16 inch (0.5625 inch) length of cut and a 2 inch overall length. An AlTiN PVD coating improves heat resistance and tool life at elevated cutting temperatures. The 35-degree medium helix angle balances chip evacuation with cutting stability across a range of workpiece materials. This is a single-end, right-hand cut, right-hand flute tool intended for CNC machining center use.
The SB335 series ball end mill is suited for 3-axis and multi-axis CNC milling operations in job shop, die-mold, and general metalworking environments. Its standard length profile and straight cylindrical shank make it compatible with common collet and end mill holder tooling systems. The combination of AlTiN coating and solid carbide substrate supports both roughing and finishing material removal strategies, particularly in ferrous and light non-ferrous applications. A licensed machinist or CNC tooling specialist typically selects and installs this tool.
Key Features
- 3/16 inch ball nose diameter with 0.0938 inch nose radius for contour and 3D surface work
- Solid carbide construction for rigidity and dimensional accuracy in demanding cuts
- AlTiN PVD coating rated for steel, cast iron, aluminum, and non-ferrous workpieces
- 35-degree medium helix angle supports efficient chip evacuation and stable cutting
- Single-end, right-hand cut design; center-cutting capable for plunge entry
- Standard length profile with straight cylindrical shank fits standard collet systems
Compatibility
Primary workpiece materials listed by manufacturer are steel, cast iron, aluminum, and non-ferrous alloys (material codes P, K, and N). The straight cylindrical shank accepts standard collet chucks and end mill holders sized for 3/16 inch shank diameter.
Installation Notes
Installation is performed by a machinist or CNC setup technician. The machine spindle must be fully stopped and the tool changer or spindle cleared before inserting or removing the tool. Seat the shank fully and evenly in the collet or holder, and verify runout against the specified TIR maximum of 0.0005 inch before cutting. Always confirm cutting parameters such as spindle speed and feed rate against the manufacturer published data for this series and workpiece material before starting a program.
