Harvey Tool 46078 Corner Rounding End Mill 1/4 in 2 Flute

Product Description

The HARVEY TOOL 46078 is a double-end corner rounding end mill designed to produce precise, consistent radius profiles on workpiece edges. Built from solid carbide, it delivers the rigidity and wear resistance required for production milling in ferrous and non-ferrous materials. The 5/64 inch radius geometry on each end creates a clean, blended corner transition. With a 1/4 inch mill diameter, 1/4 inch shank diameter, and an overall length of 2 inches, this tool fits standard collet and end mill holder setups. Machinists and tool-and-die professionals specify this type of cutter for edge-breaking, deburring, and decorative radius work on CNC and manual milling machines.

This end mill is suited for job shop, production, and tool room applications where repeatable radius profiles are required. The double-end configuration extends usable tool life by providing two cutting ends per shank. The bright uncoated finish makes it appropriate for a wide range of base materials where a specialized coating is not required. It is commonly used in aerospace, moldmaking, and general machining environments where edge quality and profile accuracy are critical.

Key Features

• Double-end design provides two usable cutting ends per tool, reducing per-edge tooling cost
• Solid carbide construction delivers superior rigidity and wear resistance versus HSS alternatives
• 5/64 inch corner radius with a 3/64 inch tip diameter for fine edge-blending work
• Bright uncoated finish suitable for general-purpose milling across a broad range of materials
• 2-flute geometry promotes chip evacuation in moderate feed-rate applications
• 1/4 inch shank diameter fits standard ER collets and end mill holders

Compatibility

Designed as a standard-shank corner rounding end mill compatible with 1/4 inch collet chucks, ER collet systems, and end mill holders used on CNC machining centers and manual knee mills.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Secure the 1/4 inch shank with appropriate collet torque per the machine tool manufacturer specification. Verify runout with a dial indicator before beginning production cuts to avoid premature tool wear or profile inaccuracy.
