Seco 17013197 Corner Chamfer End Mill 2in 4 Flute Cobalt

Product Description

The SECO 17013197 is a corner chamfer end mill from the VFP635 series, designed for high-performance material removal in demanding cutting applications. Built from M42 cobalt high-speed steel with a bright/uncoated finish, this single-end mill features a 2-inch diameter, four helical flutes, and a super close pitch configuration. The 45-degree chamfer geometry produces a controlled edge break at 0.0400 inches chamfer width. Centercutting capability allows plunge entry, and the Weldon flat shank provides positive drive retention in the holder. Licensed machinists and CNC tool-and-die professionals are the primary installers of this tool class.

The 17013197 is rated for primary use in stainless steel, superalloys, and titanium — material groups M and S in ISO classification. Its application range includes shouldering, slotting, ramp-down milling, helical interpolation, drill milling, and plunging and recessing operations. The 4-inch length of cut and 4-inch reach make it well suited to deep-pocket and full-depth slotting passes where rigidity and chip evacuation are critical concerns. The regular-length flute type and medium helix angle balance cutting force with surface finish in tough alloy work.

Key Features

• M42 cobalt construction for heat and wear resistance in stainless steel and superalloy cutting
• 45-degree chamfer angle with 0.0400-inch chamfer width for consistent edge-break geometry
• Centercutting design supports plunge entry, ramp-down, and helical interpolation
• Weldon flat shank eliminates slippage under heavy radial and axial loads
• Super close pitch with right-hand helical flutes for smooth chip flow in tough materials
• No coolant-through required — compatible with flood, mist, or dry cutting setups

Compatibility

Designed for use in applications involving stainless steel, superalloys, and titanium (ISO material groups M and S). Part of the SECO VFP635 series; manufacturer catalog number VFP635-2.000-D3-C040.3-Z6. Compatible with standard 2-inch Weldon flat end mill holders.

Installation Notes

Installation is performed by qualified machinists or CNC setup personnel. Ensure the machine spindle and tool holder are fully stopped and de-energized before changing or setting tooling. Confirm holder bore and Weldon flat setscrew engagement before running the spindle. Verify runout with a dial indicator after seating — excessive runout in large-diameter cobalt end mills accelerates edge wear and can cause chatter in hard materials.
