Harvey Tool 73098-C3 Square End Mill 2.5mm 4 Flute Altin

Product Description

The HARVEY TOOL 73098-C3 is a solid carbide square end mill designed for precision milling in demanding machining environments. With a 2.5 mm (0.0980 inch) cutting diameter and a 4-flute geometry, it delivers efficient material removal and a fine surface finish in a single-end configuration. The 30-degree helix angle promotes smooth chip evacuation and reduces cutting forces. An AlTiN (aluminum titanium nitride) coating provides elevated heat resistance and extended tool life in hard and abrasive materials. This end mill is right-hand cutting with right-hand flute direction and is center-cutting capable, allowing plunge entry. It is sized for use in precision CNC machining centers and manual mills by machinists and tooling professionals.

This end mill is suited for milling ferrous and non-ferrous metals, hardened steels, and high-temperature alloys where a small-diameter, coated carbide tool is required. The 0.125 inch shank diameter fits standard collets and tool holders commonly used in CNC machining centers, die and mold work, and precision prototype machining. The compact 1.5 inch overall length and 0.294 inch length of cut make it well matched for shallow-to-medium depth slotting, profiling, and contouring operations in tight workpiece geometries.

Key Features

• Solid carbide construction for rigidity and wear resistance in demanding cuts
• AlTiN coating for high-heat resistance and extended tool life
• 4-flute design balances chip clearance and surface finish quality
• 30-degree helix angle promotes efficient chip evacuation and reduced cutting forces
• Center-cutting geometry allows direct plunge entry
• Right-hand cut and right-hand flute direction for standard CNC spindle compatibility

Compatibility

Designed as a standard small-diameter square end mill for use in CNC machining centers and manual mills accepting a 0.125 inch shank via collet or end mill holder.

Installation Notes

Installation is performed by qualified machinists using appropriate collet chucks or end mill holders rated for the 0.125 inch shank diameter. Ensure the spindle is fully stopped and the machine is in a safe state before tool changes. Verify runout with a dial indicator after seating to minimize premature wear. Follow the tool manufacturer and machine builder guidelines for speeds, feeds, and depth of cut for the specific workpiece material and coating type.
