Hertel E1032908 Square End Mill 7/8 in 6 Flute Hss

Product Description

The HERTEL E1032908 is a 6-flute square end mill designed for milling operations in metal and ferrous materials. Manufactured from M7 high speed steel, it features a 7/8-inch cutting diameter, a 1-7/8-inch length of cut, and a 4-inch overall length with a 5/8-inch shank diameter. The spiral flute geometry with a 30-degree helix angle promotes efficient chip evacuation and smooth cutting action. This is a single-end, uncoated tool with right-hand cut and right-hand flute orientation. It is installed and operated by machinists and tool and die professionals working with manual or CNC milling equipment.

This end mill is suited for side milling, slotting, and profiling operations in job shop, production, and maintenance machining environments. The regular-length configuration fits standard tool holders and collet chucks without requiring extended-reach setups. The 6-flute design supports higher feed rates compared to lower-flute-count tools in the same diameter class. It is not centercutting and is not intended for direct plunge operations. Applications typically include ferrous alloy machining where finish and tool life under interrupted or continuous cuts are priorities.

Key Features

• M7 high speed steel construction for durability in ferrous machining
• 6-flute geometry supports higher feed rates and improved surface finish
• 30-degree helix angle promotes efficient chip evacuation
• Right-hand cut and right-hand spiral flute orientation
• Uncoated finish — suitable for applications where coating is not required or where regrinding is planned
• Regular-length configuration fits standard milling setups without extended-reach tooling

Compatibility

Designed as a standard OEM-style square end mill for use in milling machines and machining centers accepting a 5/8-inch shank diameter collet or tool holder.

Installation Notes

Installation should be performed by a qualified machinist following machine tool manufacturer guidelines. Ensure the milling machine spindle is fully powered down and locked out before installing or removing tooling. Seat the 5/8-inch shank fully and securely in a collet or end mill holder torqued to the holder manufacturer's specification. Because this tool is not centercutting, avoid direct axial plunge cuts — use ramping or helical entry strategies instead.
