Hertel 750694 Square End Mill 1/32 in 2 Flute Solid Carbide

Product Description

The HERTEL 750694 is a square end mill designed for precision milling in tight tolerances and fine detail work. Built from micrograin solid carbide with an AlTiN (aluminum titanium nitride) finish, this tool delivers hardness and heat resistance suited for cutting ferrous and non-ferrous metals. The 1/32 inch cutting diameter and 5/64 inch length of cut make it well-suited for micro-milling operations where minimal tool deflection and consistent edge integrity are critical. At 1-1/2 inches overall length with a 1/8 inch shank, it fits standard collets and toolholders common in CNC machining centers. Installation and use are handled by machinists and CNC programmers working in precision manufacturing environments.

This end mill is used in applications requiring fine detail milling, slotting, and profiling at small scales. Typical use cases include mold and die work, medical component machining, electronics, and precision aerospace parts where small-diameter tooling is required. The centercutting geometry allows for plunge entry, adding versatility in complex toolpath strategies. The 30-degree helix promotes smooth chip evacuation and reduces cutting forces at this scale.

Key Features

• 1/32 inch (0.0313 inch) cutting diameter for micro-milling and fine detail work
• Micrograin solid carbide construction for rigidity and wear resistance
• AlTiN finish increases surface hardness and thermal resistance during cutting
• 30-degree helix angle promotes chip evacuation and reduces heat buildup
• Centercutting design allows plunge milling and full-slot entry
• Right-hand cut and right-hand flute direction — standard CNC spindle compatible

Compatibility

Designed as a direct-fit replacement or standard tooling option for CNC machining centers and manual mills accepting a 1/8 inch shank diameter with standard collet or toolholder systems.

Installation Notes

Installation is performed by a machinist or CNC setup technician. Ensure the spindle is fully stopped and locked out before inserting or removing the tool from the collet or toolholder. Verify collet size matches the 1/8 inch shank diameter before seating. At this diameter, tool runout must be minimized — use a precision collet and verify TIR before production cuts to avoid premature tool breakage.
