Hertel 750770 Solid Carbide Square End Mill 2 Flute

Product Description

The HERTEL 750770 is a solid carbide square end mill designed for precision material removal in milling operations. With a 0.125-inch cutting diameter, a 0.75-inch length of cut (LOC), and a 0.125-inch shank diameter, this tool is built for tight-tolerance work in small-feature applications. The overall length (OAL) is 2.25 inches. The 2-flute geometry and 30-degree helix angle promote efficient chip evacuation in a range of materials. An AlTiN (aluminum titanium nitride) coating adds thermal resistance and wear protection for dry or semi-dry cutting environments. Licensed machinists and tool-and-die professionals are the primary users of this tool.

This end mill is suited for CNC milling centers and manual mills where small-diameter, single-end tooling is required. Center-cutting capability allows it to plunge directly into workpiece material, making it useful for slot milling, profiling, and pocket entry cuts. The right-hand cut configuration is standard for conventional spindle rotation setups. It is typically applied in precision machining shops, toolrooms, and production environments requiring repeatable small-feature geometry.

Key Features

• 0.125-inch cutting diameter for small-feature milling applications
• 0.75-inch length of cut supports moderate-depth slot and profile work
• 2-flute design promotes chip clearance and reduces cutting forces
• 30-degree helix angle balances cutting efficiency and edge stability
• AlTiN coating provides thermal and wear resistance for extended tool life
• Center-cutting geometry enables direct plunge entry into workpiece material

Compatibility

Designed as a standard solid carbide square end mill with a 0.125-inch straight shank, compatible with collet chucks and end mill holders sized to accept 0.125-inch shank tooling on CNC or manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist following standard tooling setup procedures. Ensure the spindle is fully stopped and the machine is powered down before inserting or removing the tool from the holder. Use a properly sized collet or end mill holder to achieve secure clamping and minimize runout. Verify tool projection length and depth of cut parameters before initiating a cutting cycle.
