Seco 17013183 Corner Chamfer End Mill 1in 4 Flute Cobalt

Product Description

The SECO 17013183 is a corner chamfer end mill built from M42 cobalt high-speed steel, designed for aggressive metal removal in demanding applications. With a 1-inch cutting diameter, 4-inch length of cut, and a 45-degree chamfer angle with a 0.0300-inch chamfer width, this tool is engineered for shouldering, slotting, rampdown, helical interpolation, drill milling, and plunging and recessing operations. The four-flute, right-hand helical design runs in a super-close pitch configuration, and the centercutting geometry allows direct plunge entry. This is a single-end, long-length tool suited for machinists and toolroom professionals working on precision components.

This end mill is part of the VFP635 series and is optimized for cutting stainless steel, superalloys, and titanium. Its cobalt M42 substrate provides the heat resistance and edge retention these materials demand. The Weldon flat shank design ensures positive drive and minimal slippage in high-torque milling setups. The bright uncoated finish makes it a straightforward choice when coating compatibility with workpiece material is a concern or when regrinding is planned after service.

Key Features

• M42 cobalt construction for heat resistance in stainless steel, superalloy, and titanium cuts
• 45-degree chamfer angle with 0.0300-inch chamfer width for precise edge preparation
• Centercutting geometry enables direct plunge entry without pilot drilling
• Super-close pitch with 4 helical flutes for smooth chip evacuation and reduced chatter
• Weldon flat shank provides secure, positive drive in standard end mill holders
• Supports shouldering, slotting, rampdown, helical interpolation, drill milling, and plunging operations

Compatibility

Designed for use in standard 1-inch Weldon flat end mill holders. Primary workpiece materials are stainless steel, superalloys, and titanium. Part of the SECO VFP635 series; manufacturer catalog number VFP635-1.000-D4-C030.3-Z6.

Installation Notes

Installation should be performed by a qualified machinist following shop-standard toolholder torque procedures for Weldon flat shanks. Ensure the machine spindle is fully stopped and locked out before changing tooling. Confirm runout with a dial indicator after seating the tool in the holder. Verify spindle direction is set to right-hand rotation before engaging the cut.
