Hertel E1051018 Square End Mill 9/32 in 4 Flute Hss

Product Description

The HERTEL E1051018 is a 4-flute square end mill designed for precision milling operations in metal fabrication and machining environments. Built from M7 high speed steel, it features a 9/32-inch (0.2813-inch) cutting diameter with an 11/16-inch length of cut and a 3/8-inch shank diameter. The 30-degree spiral flute geometry promotes efficient chip evacuation during slotting, profiling, and peripheral milling cuts. With an overall length of 3-3/8 inches and a double-end configuration, this tool is suited for machinists and tool-and-die professionals working on production or job-shop setups.

This end mill is intended for right-hand cut and right-hand flute operations on ferrous and non-ferrous metals. The regular length designation and uncoated HSS construction make it a practical choice for general-purpose milling where a coated or carbide tool is not required. The double-end design extends usable tool life before replacement. It is well suited for CNC machining centers, manual mills, and bridgeport-style equipment where a 3/8-inch shank collet or end mill holder is in use.

Key Features

• M7 high speed steel construction for durability in general-purpose metal milling
• 4-flute spiral design with 30-degree helix angle for efficient chip removal
• Double-end configuration extends tool service life
• Right-hand cut and right-hand flute orientation for standard milling setups
• Uncoated finish suitable for applications where coating is not required
• Non-centercutting geometry — not intended for direct plunge cuts

Compatibility

Designed as an OEM-style replacement or direct-use end mill for machines equipped with a 3/8-inch shank collet or end mill holder in standard vertical or horizontal milling configurations.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully stopped and machine power isolated. Secure the 3/8-inch shank in a properly sized collet or end mill holder and torque the drawbar or set screw per the machine manufacturer's specifications. Note that this tool is non-centercutting and should not be used for direct plunge entry into solid material — use a ramping or helical entry strategy instead. Follow applicable shop safety protocols and inspect the cutting edges before each use.
