Harvey Tool 12799-C3 Square End Mill 0.1000 in 3 Flute Carbide

Product Description

The HARVEY TOOL 12799-C3 is a solid carbide square end mill designed for precision milling in demanding machining environments. With a 0.1000 inch cutting diameter, 3-flute geometry, and a 30-degree helix angle, this tool delivers clean, accurate cuts in both roughing and finishing passes. The AlTiN coating provides high heat resistance and extended tool life when cutting hardened steels, stainless, and other tough alloys. The 0.125 inch shank diameter fits standard collets on CNC machining centers and manual mills. This end mill is a single-end, right-hand cut, right-hand flute tool suited for machinists and toolroom professionals working with tight tolerances.

This end mill is intended for use in precision CNC machining and manual milling operations across metalworking shops, tool and die environments, and production machining cells. The compact 0.1000 inch diameter makes it well suited for small-feature milling, slot cutting, and detailed contour work where larger tools cannot reach. The 0.75 inch length of cut provides adequate flute engagement for most small-part milling applications without sacrificing rigidity. Typical users include CNC machinists, toolmakers, and prototype shops requiring consistent results in difficult-to-machine materials.

Key Features

• 0.1000 inch cutting diameter for small-feature and fine-detail milling
• 3-flute solid carbide construction for rigidity and chip evacuation
• AlTiN coating for heat resistance and extended tool life in tough alloys
• 30-degree helix angle for smooth cutting action and reduced chatter
• Right-hand cut, right-hand flute, single-end configuration
• Centercutting design allows plunge entry

Compatibility

Designed for use in standard 1/8 inch collets on CNC machining centers and manual knee mills performing small-diameter end milling operations.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Secure the shank fully in a clean, properly sized collet and torque the drawbar or collet nut to the spindle manufacturer's specification. Ensure the machine spindle is fully stopped and locked out before changing tooling. At 0.1000 inch diameter, avoid side loads and excessive depth-of-cut increments that can deflect or fracture the tool.
