Seco 17013179 Corner Chamfer End Mill 1in 4 Flute Cobalt

Product Description

The SECO 17013179 is a cobalt corner chamfer end mill designed for high-performance material removal in demanding machining applications. Built to Series VFP635 standards, it features a 1-inch mill diameter, a 2-inch length of cut, and a 0.0300-inch chamfer width at a 45-degree chamfer angle. The four-flute, right-hand helical design with a super-close pitch enables aggressive roughing passes while maintaining edge stability. The Weldon flat shank and 4.5-inch overall length make this tool a practical fit for vertical and horizontal milling setups. Licensed machinists and CNC operators working in job shops and production environments are the typical end users for this tooling.

This end mill is engineered primarily for use on stainless steel, superalloys, and titanium — workpiece material codes M and S. It supports a wide range of milling operations including shouldering, slotting, rampdown, helical interpolation, drill mill operations, and plunging and recessing. The centercutting geometry enables direct plunge entry without a pre-drilled pilot hole, adding versatility to the tool's application range. The M42 cobalt material grade provides heat resistance suited to the elevated cutting temperatures common when machining nickel-based superalloys and titanium alloys.

Key Features

• 1-inch mill diameter with 1-inch Weldon flat shank for secure, anti-rotation clamping
• 0.0300-inch chamfer width at 45 degrees for consistent edge-breaking and chamfering passes
• M42 cobalt construction for elevated heat and wear resistance in superalloy and titanium cutting
• Centercutting design allows direct plunge entry without a pre-drilled hole
• Super-close pitch with helical flutes supports roughing operations including slotting and helical interpolation
• Bright/uncoated finish — no coating build-up concerns on edge geometry

Compatibility

Designed for use with stainless steel, superalloys, and titanium workpiece materials (material codes M and S). Part of the SECO VFP635 series; manufacturer catalog number VFP635-1.000-D2-C030.3-Z6.

Installation Notes

This tool is installed by machinists and CNC programmers operating milling machines or machining centers. Secure the Weldon flat shank in a compatible end mill holder with a set screw aligned to the flat before torquing to the holder manufacturer's specification. Verify spindle runout and tool projection before commencing cuts, particularly when machining superalloys where deflection directly affects tool life. Always follow the machine tool manufacturer's safe operating procedures and applicable shop safety standards when changing or setting tooling.
