Hertel E899921287 Square End Mill 13/32 in 2 Flute Hss

Product Description

The HERTEL E899921287 is a 2-flute square end mill manufactured from high speed steel with a titanium nitride (TiN) coating. It features a 13/32-inch (0.4063-inch) mill diameter, a 1-3/4-inch length of cut, and a 1/2-inch shank diameter with a 3-1/4-inch overall length. The 30-degree spiral flute geometry and right-hand cut with right-hand flute configuration promote efficient chip evacuation and consistent surface finishes. The centercutting design allows plunge milling as well as standard peripheral cuts. This tool is suited for machining operations in job shops, tool rooms, and production environments where HSS tooling is appropriate.

This end mill is designed for use in vertical milling machines, knee mills, and CNC machining centers running appropriate feeds and speeds for HSS tooling. The 2-flute configuration is commonly used when machining softer materials such as aluminum, plastics, and mild steels where chip clearance is a priority. The TiN finish extends tool life and reduces friction compared to uncoated HSS. It is a single-end tool, meaning service life is exhausted when the cutting end dulls and the tool is not reversible.

Key Features

• 13/32-inch (0.4063-inch) mill diameter with 1-3/4-inch length of cut
• High speed steel construction with titanium nitride (TiN) coating for extended tool life
• 2-flute spiral design with 30-degree helix angle for efficient chip removal
• Centercutting geometry enables plunge cuts as well as side milling
• Right-hand cut, right-hand flute configuration for standard milling setups
• 1/2-inch shank diameter for compatibility with standard collets and end mill holders

Compatibility

Designed for use in standard end mill holders, ER collet chucks, and milling machine spindles accepting a 1/2-inch shank. Consult machine specifications and material cutting data charts to confirm appropriate speeds and feeds before use.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines. Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Secure the shank to the minimum recommended insertion depth as specified by the tool holder manufacturer. Confirm runout with a dial indicator after seating to avoid premature tool wear or breakage.
