Hertel 750030 Square End Mill 1/32 in 4 Flute Solid Carbide

Product Description

The HERTEL 750030 is a solid carbide square end mill designed for precision milling of metals, composites, and hard materials. With a 1/32 inch (0.0313 inch) cutting diameter and 4 flutes, this tool delivers fine detail cuts with good chip evacuation in tight geometries. The 30-degree helix angle balances cutting efficiency and surface finish. Centercutting geometry allows the tool to plunge directly into the workpiece. The micrograin carbide substrate provides wear resistance and edge retention suitable for production environments. Machinists and tool-and-die professionals install this tool in CNC machining centers and manual mills requiring high-precision small-diameter work.

This end mill suits applications in mold and die work, medical device manufacturing, aerospace component machining, and any operation requiring fine-detail slotting or profiling in a small diameter. The right-hand cutting and right-hand spiral flute direction are standard for conventional CNC setups. The 1/8 inch shank diameter fits standard collets and tool holders common in small-diameter tooling setups. The bright/uncoated finish makes it suitable for a range of base materials where coating is not required or where regrinding is anticipated.

Key Features

• 1/32 inch (0.0313 inch) cutting diameter for fine-detail and micro-milling operations
• 4-flute design improves surface finish and feed rate capability versus 2-flute equivalents
• Solid micrograin carbide construction for edge retention in hard and abrasive materials
• Centercutting geometry enables direct plunge entry into the workpiece
• 30-degree helix angle balances chip flow and lateral cutting forces
• Bright/uncoated finish allows regrinding and suits a broad range of workpiece materials

Compatibility

Designed as a standard small-diameter square end mill for use in CNC machining centers and manual mills equipped with collet systems accepting a 1/8 inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist following shop safety protocols. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the shank fully and evenly in the collet to the recommended engagement depth per the collet manufacturer before tightening. At 1/32 inch diameter, this tool is highly susceptible to breakage from runout, improper feeds and speeds, or lateral shock — verify collet condition and runout before use.
