Seco 17013184 Corner Chamfer End Mill 1-1/4 in 4 Flute Cobalt

Product Description

The SECO 17013184 is a corner chamfer end mill from the VFP635 series, built from M42 cobalt high-speed steel for demanding material removal in stainless steel, superalloys, and titanium. The cutter measures 1.25 inches in diameter with a 2-inch length of cut and a 4.5-inch overall length. Four helical flutes with a super-close pitch and right-hand cutting direction provide aggressive stock removal with improved surface finish. The 45-degree chamfer at 0.0400 inches wide breaks the sharp corner on the workpiece edge. The bright uncoated finish makes it a solid choice where coating adhesion or regrinding convenience matters. Licensed machinists and tool-and-die professionals are the primary installers and operators.

This end mill is suited for roughing operations in demanding materials including stainless steel, superalloys, and titanium. Its centercutting design enables shouldering, slotting, rampdown, helical interpolation, drill milling, plunging, and recessing operations. The Weldon flat shank provides a positive grip in side-lock holders, reducing pullout risk under heavy cuts. The short flute length geometry is appropriate for applications requiring rigidity over reach. With its super-close pitch construction, it handles interrupted cuts and difficult-to-machine alloys where conventional end mills deflect or chatter.

Key Features

• M42 cobalt construction for high heat and wear resistance in stainless steel, superalloys, and titanium
• 45-degree chamfer angle with 0.0400 inch chamfer width for consistent edge breaking
• Centercutting design supports plunging, rampdown, and helical interpolation
• Super-close pitch with medium helix for chip control in tough alloys
• Weldon flat shank for secure tool holding in side-lock and set-screw holders
• Right-hand flute direction and cutting direction; single-end configuration

Compatibility

Designed for use in standard milling machine spindles and CNC machining centers accepting a 1.25-inch diameter Weldon flat shank. Optimized for primary workpiece materials coded M and S: stainless steel, superalloys, and titanium per ISO material classification. Catalog reference VFP435-1.250-D2-C040.3-Z4.

Installation Notes

Installation is performed by a qualified machinist or CNC operator. Secure the Weldon flat shank in a side-lock or set-screw holder, confirming the flat is fully engaged before tightening. Confirm spindle runout is within acceptable tolerance before starting the cut, as excess runout accelerates edge wear on cobalt tooling. Do not exceed the tool manufacturer's recommended feed and speed parameters for the workpiece material grade.
