Hertel E899913327 Square End Mill 2in 8 Flute Hss Tin

Product Description

The HERTEL E899913327 is a square end mill designed for milling operations requiring a sharp corner profile and high material removal rates. Built from M7 high speed steel with a titanium nitride (TiN) coating, it delivers extended tool life in ferrous and non-ferrous materials. The 8-flute configuration provides a high flute count for improved surface finish on finishing passes. With a 2-inch mill diameter, 1.5-inch length of cut, and a 30-degree helix angle, this end mill suits both conventional and climb milling setups. Installation and setup are handled by machinists and CNC tooling technicians in production and job-shop environments.

This end mill is suited for horizontal and vertical milling machines, CNC machining centers, and manual knee mills where a 0.75-inch shank diameter is accommodated. It is appropriate for finishing and semi-finishing passes on steel, alloy steel, and similar materials. The non-centercutting design means it is intended for peripheral and side milling rather than plunge cutting. Its 3.875-inch overall length provides adequate reach for most standard fixturing setups without excessive overhang.

Key Features

• 2-inch mill diameter with 8 flutes for high surface finish quality
• M7 high speed steel construction with TiN coating for wear resistance
• 30-degree right-hand spiral helix angle for efficient chip evacuation
• 0.75-inch shank diameter fits standard ER and shell mill holders
• Non-centercutting geometry — suitable for side and peripheral milling only
• Right-hand cutting direction compatible with standard spindle rotation

Compatibility

Designed as an OEM-style replacement and standard tooling option for milling machines and CNC machining centers accepting a 0.75-inch straight shank end mill holder.

Installation Notes

This tool is installed by machinists or CNC tooling technicians. Ensure the spindle is fully de-energized and locked out before changing tooling. Verify holder runout and shank seating before tightening to prevent premature edge wear. Because this is a non-centercutting end mill, do not use it for direct plunge cuts into solid material.
