Hertel GH07001619 Square End Mill 0.25in 2-flute Hss

Product Description

The HERTEL GH07001619 is a single-end square end mill designed for precise milling operations in metal and similar materials. Manufactured from M7 high speed steel and finished with a titanium nitride (TiN) coating, it delivers improved surface hardness and heat resistance compared to uncoated HSS tooling. The mill measures 0.25 inches in diameter with a 0.625-inch length of cut, a 0.375-inch shank diameter, and a 2.5-inch overall length. Its 42-degree helix angle and two-flute spiral geometry promote efficient chip evacuation and clean cutting action. This tool is installed by machinists and tool-and-die technicians working with manual or CNC milling equipment.

This end mill suits light-to-medium material removal in ferrous and non-ferrous metals, plastics, and similar workpiece materials. Its centercutting geometry allows plunge entry directly into the workpiece without a pre-drilled pilot hole. The right-hand cut, right-hand flute configuration is standard for conventional milling setups. The regular-length profile fits most standard milling collets and chucks. Applications include slotting, profiling, and pocket milling in both job-shop and production environments.

Key Features

• M7 high speed steel construction for durability in ferrous and general-purpose milling
• TiN coating increases surface hardness and reduces heat buildup at the cutting edge
• 42-degree helix angle promotes aggressive chip evacuation and smooth cutting action
• Centercutting design allows direct plunge milling without a starter hole
• Two-flute spiral geometry suited for slotting and full-width cuts
• Right-hand cut and right-hand flute configuration for standard milling spindle direction

Compatibility

Designed as an OEM-style replacement or standard tooling option for milling operations requiring a 0.375-inch shank, 0.25-inch diameter square end mill in regular-length configuration.

Installation Notes

This end mill is installed by machinists using a compatible collet or end mill holder sized for a 0.375-inch shank. Ensure the spindle is fully stopped and the machine is de-energized before changing tooling. Confirm runout with a dial indicator after seating the tool to avoid premature edge wear. Follow the machine tool manufacturer guidelines and applicable shop safety procedures for speeds, feeds, and workholding.
