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

Product Description

The HARVEY TOOL 17078 is a double-end corner rounding end mill designed to produce consistent radius profiles on workpiece edges. Built from solid carbide, it delivers the rigidity and wear resistance needed for demanding milling operations on ferrous and non-ferrous materials. The 5/64 inch radius profile and 0.046 inch tip diameter make it suited for small-feature edge work where precision matters. With a 1/4 inch mill diameter, 1/4 inch shank, and 2 inch overall length, this tool fits standard collets and tool holders common in CNC machining centers and manual mills. The bright uncoated finish keeps the geometry clean for general-purpose use. Machinists and tool-and-die professionals rely on this geometry for deburring, edge blending, and profile rounding in production and prototype environments.

This end mill is used in CNC machining centers, knee mills, and tool-and-die operations where a consistent corner radius must be applied to part edges. The double-end configuration provides two usable cutting ends, extending tool life between changes. It suits applications in aerospace, automotive, mold-making, and general metalworking where edge blending and radius profiling are required. The 2-flute design aids chip evacuation in slotting and profiling passes.

Key Features

• Solid carbide construction for rigidity and extended tool life in metalworking applications
• 5/64 inch corner radius for precise edge rounding and blending
• Double-end design provides two cutting ends per tool
• 2-flute geometry promotes chip clearance during profiling passes
• Bright uncoated finish suitable for general-purpose milling without coating-related dimensional offset
• 1/4 inch shank fits standard collets and ER-style tool holders

Compatibility

Designed as an OEM-style corner rounding end mill for use with standard 1/4 inch collets and tool holders in CNC machining centers, manual mills, and similar machine tool setups.

Installation Notes

Installation is performed by qualified machinists following standard tool-change procedures. Power down and lock out the spindle before seating or removing the tool. Seat the shank fully into the collet or tool holder and torque the retention nut per the machine manufacturer specifications. Inspect the cutting edges for chips or damage before each use, as carbide tooling is brittle and can fracture if mishandled.
