Harvey Tool 836325-C3 Square End Mill 0.025 in 3 Flute

Product Description

The HARVEY TOOL 836325-C3 is a solid carbide square end mill designed for precision milling in demanding machining applications. With a 0.025-inch cutting diameter and three flutes, it delivers clean material removal in tight geometries where rigidity and sharpness are critical. The AlTiN (aluminum titanium nitride) coating extends tool life by increasing surface hardness and heat resistance at the cutting edge. A 30-degree helix angle promotes smooth chip evacuation and reduces cutting forces. This tool is selected by machinists and tool-and-die professionals working in high-precision environments where micro-diameter tooling is required.

This end mill is suited for slotting, profiling, and finishing passes in materials such as hardened steels, stainless steels, titanium, and high-temperature alloys where AlTiN coatings perform best. The 0.025-inch diameter and 1.9 mm length of cut make it appropriate for fine-detail work, engraving paths, narrow slots, and contoured features on small workpieces. The 1/8-inch shank diameter allows it to seat in standard collets and end mill holders commonly found on CNC machining centers and manual mills equipped for small tooling.

Key Features

• 0.025-inch cutting diameter for micro-scale and precision milling operations
• Three-flute geometry balances chip clearance and edge strength at small diameters
• AlTiN coating provides elevated heat resistance and extended tool life in ferrous and exotic alloys
• 30-degree right-hand helix promotes efficient chip evacuation and reduces chatter
• Center-cutting capability allows direct plunge entry
• Solid carbide construction delivers the rigidity needed at sub-1/8-inch diameters

Compatibility

Designed as an OEM-style precision cutting tool for use in CNC machining centers and manual mills equipped with collet systems or end mill holders accepting a 1/8-inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and locked out before inserting or removing tooling. Seat the shank fully into the collet or holder to the recommended grip length and torque the collet nut per the tool-holder manufacturer specification. At micro diameters, runout control is critical — verify TIR with a dial indicator before beginning a cut to avoid premature tool breakage.
