Harvey Tool 17080-C3 Corner Rounding End Mill 1/4 in 2 Flute

Product Description

The HARVEY TOOL 17080-C3 is a double-end corner rounding end mill designed for machining precise radius profiles on workpiece edges. Built from solid carbide with an AlTiN (aluminum titanium nitride) coating, this tool delivers extended wear resistance in ferrous and hard-material applications. It features a 0.08-inch corner radius, a 0.25-inch mill diameter, and a 0.046-inch tip diameter, making it well-suited for fine-detail edge work where consistent radius geometry is critical. The 2-flute configuration supports efficient chip evacuation in a wide range of milling operations. This tool is part of the Corner Rounding End Mills Flared Series.

This end mill is used in CNC milling operations requiring repeatable edge-break or radius profiles on metals, including alloy steels, stainless, and hardened materials. The AlTiN coating makes it particularly effective in dry or semi-dry cutting environments at elevated temperatures. The double-end design maximizes tool life per unit, allowing machinists to index to the second end before replacement. Typical applications include die and mold work, aerospace component finishing, and precision part edge profiling in both job-shop and production environments.

Key Features

• Double-end design extends usable tool life by providing two cutting ends per shank
• AlTiN coating improves heat resistance and wear performance in ferrous and hardened materials
• Solid carbide construction provides rigidity and dimensional stability under high-speed cutting loads
• 0.08-inch corner radius with 0.046-inch tip diameter for precise edge-profile geometry
• 2-flute geometry promotes chip clearance in slotting and profiling passes
• Flared series geometry designed for consistent radius formation along the full cutting edge

Compatibility

Designed as an OEM-style replacement or direct-use corner rounding end mill compatible with standard CNC machining centers and manual mills accepting a 1/4-inch straight shank toolholder.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Seat the 1/4-inch shank fully into the collet or toolholder and torque the retention hardware per the toolholder manufacturer specifications. Verify runout with a dial indicator before commencing a production cut to protect both the tool and the workpiece.
