Harvey Tool 17078-C3 Corner Rounding End Mill 1/4 in 2 Flute

Product Description

The HARVEY TOOL 17078-C3 is a double-end, solid carbide corner rounding end mill designed for edge-profiling and radius-breaking operations on ferrous and non-ferrous workpieces. It produces a 5/64 inch radius profile on a 1/4 inch diameter cutter body, with a tip diameter of 0.046 inches. The AlTiN coating provides thermal resistance and extended tool life in high-speed, dry, or semi-dry cutting environments. With a 2-flute configuration and a double-end design, this tool delivers two usable cutting ends from a single shank, making it a practical choice for production shops and tool rooms alike.

This end mill is suited for milling machines, machining centers, and CNC routers where consistent edge rounding and chamfer blending are required. It performs well in steel, stainless steel, cast iron, and hardened alloys where an AlTiN coating is appropriate. The 1/4 inch shank diameter accepts standard ER collet chucks, end mill holders, and precision collet systems common in both vertical and horizontal machining setups. Machinists, tool-and-die makers, and CNC operators handling tight-tolerance edge-break work will find this a direct-fit solution.

Key Features

• 5/64 inch radius profile for consistent, repeatable corner rounding
• Double-end design provides two cutting ends per tool, extending usable tool life
• AlTiN coating improves heat resistance and wear performance in ferrous materials
• Solid carbide construction for rigidity and dimensional stability at high spindle speeds
• 2-flute geometry supports chip evacuation in slotting and profiling passes
• 1/4 inch shank diameter fits standard collet and end mill holder systems

Compatibility

Designed as an OEM-style cutting tool for use in any 1/4 inch collet or end mill holder on vertical or horizontal machining centers and CNC milling machines.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before loading or exchanging tooling. Seat the shank fully into the collet or holder to the recommended gauge line and torque the retention hardware per the toolholder manufacturer specifications. Verify runout with a dial indicator before beginning a production run, as excessive runout will accelerate edge wear on carbide tooling.
