Harvey Tool 31660-C3 Corner Rounding End Mill 1/4 in 2 Flute

Product Description

The HARVEY TOOL 31660-C3 is a solid carbide corner rounding end mill designed to produce precise radius profiles on workpiece edges and contours. It features a 0.06 mm corner radius, a 0.25-inch mill diameter, and a 0.046-inch tip diameter, making it suited for fine detail work in tight areas. The AlTiN coating provides thermal resistance and wear protection during high-speed cutting operations. With a double-end configuration and 2-flute geometry, this tool delivers efficient chip evacuation and is used by machinists working in CNC milling applications across metals and hardened materials.

This end mill is appropriate for use in precision machining environments including job shops, toolrooms, and production facilities. The flared series geometry is built for corner rounding operations where edge blending, radius forming, or chamfer profiling is required. With a 4-inch overall length and 0.25-inch shank diameter, it mounts in standard collet toolholding systems. The double-end design extends tool life by providing a second usable cutting end. It is installed and operated by machinists and CNC programmers working with vertical or horizontal milling centers.

Key Features

• 0.06 mm corner radius for precise edge rounding and blending operations
• Solid carbide construction for rigidity and wear resistance in demanding cuts
• AlTiN coating enhances heat resistance and extends tool life at elevated cutting speeds
• Double-end design provides two cutting ends, maximizing tool value and longevity
• 2-flute geometry promotes efficient chip evacuation in milling operations
• 4-inch overall length accommodates setups requiring additional reach clearance

Compatibility

Designed for use in standard 0.25-inch collet or toolholder systems on CNC vertical and horizontal milling machines. Part of the Harvey Tool Corner Rounding End Mills 2 and 4 Flute Flared series.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the spindle is fully powered down and the machine is in a safe state before mounting or removing the tool. Seat the shank fully in a clean, properly sized collet or toolholder and torque the retention hardware per the toolholder manufacturer specifications. Verify runout with a dial indicator before beginning a cutting pass.
