Hertel GH070056 Square End Mill 7/8 in 2 Flute Hss Tin

Product Description

The HERTEL GH070056 is a square end mill designed for general-purpose milling operations in metal fabrication and machine shop environments. Built from M7 high speed steel with a titanium nitride (TiN) coating, it delivers solid wear resistance and extended tool life in ferrous and non-ferrous materials. The cutter measures 7/8 inch in diameter with a 1-7/8 inch length of cut and a 4-1/8 inch overall length. Its 42-degree helix angle promotes efficient chip evacuation, and the two-flute design provides good chip clearance in slotting and peripheral milling applications. This is a single-end, centercutting tool, making it capable of plunge entry as well as conventional end milling operations.

This end mill is suited for use in vertical machining centers, knee mills, and manual milling machines running at appropriate surface footage for HSS tooling. The 7/8 inch shank diameter fits standard collets and end mill holders of the same bore size. It is a regular-length tool appropriate for side milling, slot cutting, profiling, and light contouring. Machinists and tool and die technicians are the primary users. Both right-hand cut and right-hand flute configuration are standard on this tool.

Key Features

• M7 high speed steel construction for durability in general milling applications
• TiN (titanium nitride) finish increases surface hardness and reduces friction
• 42-degree spiral helix angle promotes efficient chip flow and reduced chatter
• Centercutting design allows direct plunge entry without a pre-drilled hole
• Two-flute geometry maximizes chip clearance in slot milling operations
• Right-hand cut, right-hand flute — standard orientation for most milling setups

Compatibility

Designed as an OEM-style replacement or standard stock end mill for use in any milling machine or machining center equipped with a 7/8 inch collet, end mill holder, or equivalent toolholding system rated for HSS tooling at appropriate spindle speeds.

Installation Notes

Installation should be performed by a qualified machinist familiar with proper toolholding torque procedures for the specific holder type in use. Ensure the machine spindle is fully stopped and the machine is powered down before inserting or removing the end mill. Secure the shank to the full recommended engagement depth in the holder to prevent pullout under cutting loads. Follow the tool manufacturer and machine manufacturer guidelines for surface footage and feed rates appropriate to M7 HSS tooling.
