Hertel E599924443 Square End Mill 1/32 in 3 Flute Carbide

Product Description

The HERTEL E599924443 is a solid carbide square end mill designed for precision milling in tight-tolerance applications. Built from micrograin carbide, it measures 0.0313 inches in cutting diameter with a 3/32-inch (0.0938 inch) length of cut and a 1/8-inch shank diameter, making it well-suited for fine detail work in small-feature machining. The double-end configuration and centercutting geometry allow direct plunge entry without a pre-drilled hole. Three right-hand flutes with a 30-degree helix angle promote efficient chip evacuation and surface finish quality. Machinists and tool-and-die professionals use this end mill on CNC machining centers and manual mills where small-diameter, high-precision cuts are required.

This end mill is intended for small-feature milling operations in materials that respond well to uncoated micrograin carbide tooling, including aluminum, brass, soft steels, and plastics. The 1-1/2-inch overall length keeps deflection low at this diameter, which is critical when cutting fine slots, contours, or pockets. The double-end design effectively doubles tool life by providing a second usable cutting end. It is packaged and sold individually and is a direct catalog replacement for shops sourcing standard solid carbide square end mills in this size range.

Key Features

• Micrograin solid carbide construction for rigidity and wear resistance at small diameters
• Centercutting geometry allows direct plunge milling without pilot hole
• Double-end design provides two cutting ends per tool
• 30-degree right-hand helix for efficient chip flow and improved surface finish
• Three flutes balance chip clearance and cutting edge strength
• Uncoated finish suitable for non-ferrous metals and plastics

Compatibility

Designed as an OEM-style replacement for standard solid carbide square end mills in the 1/32-inch diameter class, compatible with any CNC or manual milling machine spindle accepting a 1/8-inch shank.

Installation Notes

Installation should be performed by a qualified machinist following standard tool change procedures. Ensure the spindle is fully stopped and de-energized before changing tooling. Seat the 1/8-inch shank fully and evenly in the collet or end mill holder and torque the collet nut to the machine manufacturer specification. At this diameter, runout control is critical — use a high-precision collet to minimize deflection and tool breakage.
