Seco 17013175 Corner Chamfer End Mill 0.75in 4 Flute Cobalt

Product Description

The SECO 17013175 is a corner chamfer end mill designed for precision material removal in demanding machining applications. Built from M42 cobalt high-speed steel, this tool delivers the heat and wear resistance required when cutting stainless steel, superalloys, and titanium. It runs a 0.75 inch diameter with a 2.25 inch length of cut and a 0.0300 inch chamfer width at a 45-degree chamfer angle. The 4-flute, right-hand helical geometry and super close pitch make it well suited for shouldering, slotting, ramp-down entry, helical interpolation, and plunging operations. It is a single-end, centercutting tool, meaning it can engage a workpiece axially as well as radially.

This end mill is intended for use in CNC machining centers and manual milling machines where tight tolerances and hard-material capability are priorities. Primary target materials are stainless steel, superalloys, and titanium, making it a standard choice in aerospace, medical device, and industrial manufacturing environments. The Weldon flat shank provides positive drive engagement and minimizes tool pullout under heavy cuts. It ships bright and uncoated, which keeps cutting geometry sharp and predictable without coating buildup on edge geometry.

Key Features

• M42 cobalt construction for elevated heat resistance in hard and abrasive workpiece materials
• 0.0300 inch chamfer width at 45 degrees for consistent edge breaking and corner protection
• Centercutting design allows axial plunging and ramp-down entry without a pre-drilled hole
• Weldon flat shank reduces slippage under high torque and aggressive feed rates
• Super close pitch and 4-flute helical geometry support shouldering, slotting, and helical interpolation
• Bright uncoated finish preserves sharp edge geometry for close-tolerance finishing passes

Compatibility

Part of the SECO VFP635 series, catalog number VFP435-0.750-D3-C030.3-Z4. Designed for machining stainless steel, superalloys, and titanium in applications including shouldering, slotting, ramp-down, helical interpolation, drill mill, and plunging and recessing operations.

Installation Notes

Installation is performed by a machinist or tooling technician. The Weldon flat shank requires a set-screw style tool holder torqued against the flat to prevent axial pullout during cutting. Confirm runout with a dial indicator before beginning a production run. Follow shop safety procedures and machine manufacturer guidelines when setting tool offsets and establishing feeds and speeds for cobalt tooling in hard materials.
