Seco 17016486 Ball End Mill 3/16 in 4 Flute Cobalt Ticn

Product Description

The SECO 17016486 is a single-end cobalt ball end mill from the SPB540 series, designed for precision milling operations across a wide range of metallic workpiece materials. The cutter measures 3/16 inch (0.1875 inch) in diameter with a 1/2 inch length of cut and a 2-3/8 inch overall length. A TiCN (titanium carbonitride) PVD coating increases surface hardness and wear resistance, extending tool life in demanding applications. The 4-flute, right-hand spiral configuration with a 30-degree helix angle balances chip evacuation and surface finish. The 3/8 inch Weldon Flat shank provides positive drive and reduces slippage in the spindle holder.

This end mill is suited for roughing and finishing passes in steel, stainless steel, cast iron, aluminum and non-ferrous metals, and high-temperature alloys. The center-cutting geometry allows direct plunging into the workpiece, making it practical for profiling, contouring, slotting, and 3D surface work on CNC machining centers and manual mills equipped with a compatible collet or end mill holder. The standard length design fits most conventional setups without requiring extended-reach tooling.

Key Features

• Cobalt substrate provides elevated heat and wear resistance compared to standard high-speed steel
• TiCN PVD coating (Coating Classification: PVD) increases surface hardness for extended tool life
• 4-flute right-hand spiral with 30-degree medium helix balances chip flow and finish quality
• Center-cutting geometry allows direct plunge entry into the workpiece
• Weldon Flat shank (3/8 inch) reduces rotational slippage in end mill holders
• Rated for roughing and finishing in steel, stainless steel, cast iron, aluminum, non-ferrous, and high-temp alloys

Compatibility

Designed as an OEM-style replacement or direct-fit tool for CNC and manual milling machines accepting a 3/8 inch Weldon Flat shank end mill holder; part of the SECO SPB540 series (Manufacturers Catalog Number: SPB540-0.188-F3-B.3-Z4).

Installation Notes

Installation is performed by a machinist or toolroom technician using a torque-rated end mill holder or collet chuck compatible with the 3/8 inch Weldon Flat shank. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Verify runout with a dial indicator after seating the tool; maximum TIR for this cutter is 0.0010 inch. Follow the machine manufacturer and applicable shop safety guidelines for speeds, feeds, and coolant strategy for the workpiece material being machined.
