Hertel E8030909 Square End Mill 1 in 2 Flute Hss Tin

Product Description

The HERTEL E8030909 is a single-end square end mill designed for general-purpose milling operations in metal cutting environments. Manufactured from M7 high speed steel and finished with a titanium nitride (TiN) coating, this tool offers improved surface hardness and heat resistance compared to uncoated HSS. The 1-inch cutting diameter and 2-flute spiral design provide efficient chip evacuation and a clean shoulder cut. With a 30-degree helix angle and right-hand cut with right-hand flute, it suits conventional and climb milling on ferrous and non-ferrous materials. This end mill weighs 0.52 pounds and is sized for use in standard vertical mills and CNC machining centers.

This end mill is used in machine shops, tool rooms, and production environments for slotting, profiling, and peripheral milling. The centercutting geometry allows direct plunge entry into the workpiece, making it suitable for pocketing and closed-bottom slot work. The regular length configuration and 0.75-inch shank diameter fit standard ER and side-lock toolholders commonly found in vertical mills and knee mills. It is appropriate for use on mild steel, alloy steel, aluminum, and similar machinable materials at appropriate feeds and speeds for HSS tooling.

Key Features

• M7 high speed steel construction with TiN coating for extended tool life
• Centercutting design supports direct plunge milling and pocket entry
• 30-degree helix angle promotes smooth cutting action and chip flow
• 2-flute spiral geometry maximizes chip clearance in slotting applications
• Right-hand cut and right-hand flute — compatible with standard spindle rotation
• Single-end configuration with regular length for rigid overhang control

Compatibility

Designed as an OEM-style replacement or direct-use end mill for standard 3/4-inch shank toolholding systems in vertical mills, knee mills, and CNC machining centers.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Always power down and lock out the spindle before changing tooling. Ensure the shank is fully seated and properly torqued in the toolholder collet or side-lock adapter before operation. Inspect the cutting edges for chips or wear before each use and do not exceed recommended feeds and speeds for HSS end mills.
