Hertel 750630 Square End Mill 3/32 in 4 Flute Solid Carbide

Product Description

The HERTEL 750630 is a 4-flute solid carbide square end mill designed for precision milling in ferrous and non-ferrous materials. At 3/32 inch (0.0938 inch) in diameter with a 3/16 inch length of cut and a 1/8 inch shank, this tool is built for tight-tolerance work in small-bore and detail milling applications. The AlTiN coating provides heat resistance and extended tool life in dry or semi-dry cutting conditions. A 30-degree spiral helix angle promotes efficient chip evacuation, and the centercutting design allows plunge entry without a pre-drilled hole. Micrograin carbide construction supports higher feed rates and longer run times compared to standard carbide grades.

This end mill suits CNC machining centers, manual mills, and precision die-and-mold work where small-diameter tooling is required. It is well suited for slotting, profiling, and pocket milling in materials such as hardened steels, stainless steel, cast iron, and high-temp alloys. The right-hand cut and right-hand flute configuration is standard for conventional CNC spindle rotation. Machinists working in tool rooms, job shops, and production environments will find this tool appropriate for fine-detail contouring and finish passes.

Key Features

• 3/32 inch (0.0938 inch) mill diameter for small-feature and detail milling
• AlTiN finish for elevated heat resistance and extended tool life in hard materials
• Micrograin solid carbide construction for rigidity and wear resistance
• 4-flute, 30-degree spiral helix for efficient chip evacuation and smooth finish
• Centercutting geometry allows direct plunge entry
• Right-hand cut, right-hand flute — standard configuration for CNC and manual mills

Compatibility

Designed as a standard single-end square end mill with a 1/8 inch shank, compatible with collets, end mill holders, and tool holders sized for 1/8 inch shank tooling on CNC machining centers and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist. Secure the shank fully within the collet or tool holder to the recommended engagement depth before tightening. Verify spindle runout with a dial indicator before commencing cuts, as runout is critical with small-diameter carbide tools. Inspect the cutting edges for chips or damage before each use — do not run a damaged carbide tool.
