Harvey Tool 12759-C3 Square End Mill 1.5mm 3 Flute Altin

Product Description

The HARVEY TOOL 12759-C3 is a solid carbide square end mill designed for precise milling operations in demanding machining environments. With a 1.5 mm (0.0590 inch) cutting diameter and a 12 mm (0.472 inch) length of cut, this three-flute tool delivers clean, accurate material removal in ferrous and non-ferrous metals. The AlTiN (aluminum titanium nitride) coating increases surface hardness and heat resistance, extending tool life in high-speed applications. A 30-degree helix angle promotes smooth chip evacuation and reduces cutting forces during operation. This end mill is installed and operated by machinists and CNC programmers working with precision milling equipment.

This end mill is suited for slot milling, peripheral milling, and light plunge operations in materials such as steel, stainless steel, and hardened alloys where a small-diameter, coated carbide tool is required. The 1/8 inch (0.125 inch) shank diameter fits standard collet systems commonly found on CNC machining centers and manual mills. The 2.5 inch overall length provides adequate reach for most standard fixturing setups while maintaining rigidity at this diameter. Note that this tool is not centercutting and is not intended for direct plunge drilling.

Key Features

• 1.5 mm cutting diameter with 12 mm length of cut for precise small-feature milling
• AlTiN coating for improved heat resistance and extended tool life in ferrous materials
• Three-flute geometry balances chip load capacity and evacuation efficiency
• 30-degree right-hand helix promotes smooth cutting action and reduced vibration
• Solid carbide construction for rigidity and dimensional stability
• 1/8 inch shank diameter compatible with standard collet toolholding systems

Compatibility

Designed for use in CNC machining centers and manual mills equipped with collet systems accepting a 1/8 inch shank diameter. Not centercutting; direct plunge entry is not recommended.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank fully into the collet and tighten to the toolholder manufacturer's specification to prevent pullout at small diameters. Verify runout after installation, as excessive runout at this diameter will accelerate wear and reduce accuracy.
