Hertel 750147 Square End Mill 11/64 in 2 Flute Carbide

Product Description

The HERTEL 750147 is a solid carbide square end mill designed for precision milling in metalworking and machining applications. With an 11/64 inch (0.1719 inch) cutting diameter and a 9/16 inch length of cut, this tool handles slotting, profiling, and peripheral milling in tight-tolerance work. The 2-flute, 30-degree spiral helix geometry promotes efficient chip evacuation. The uncoated carbide construction delivers rigidity and wear resistance suitable for a range of ferrous and non-ferrous materials. Centercutting capability allows plunge entry without a pre-drilled hole, giving machinists added flexibility during setup.

This end mill is sized for small-diameter work on CNC machining centers, knee mills, and manual milling machines. The 3/16 inch shank diameter fits standard ER collets and end mill holders commonly found in production and job-shop environments. The 2 inch overall length keeps tool overhang minimal, supporting rigidity during cuts. Right-hand cutting direction is standard for conventional spindle rotation. This tool suits precision component work in aerospace, medical device, tooling, and general manufacturing contexts where small-diameter accuracy is required.

Key Features

• 11/64 inch (0.1719 inch) cutting diameter for small-diameter precision milling
• Solid carbide construction for rigidity and extended tool life
• 2-flute spiral geometry with 30-degree helix for effective chip evacuation
• Centercutting design allows direct plunge entry
• Right-hand cut with uncoated finish suitable for a broad material range
• 3/16 inch shank fits standard ER collets and end mill holders

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide square end mill for standard 3/16 inch shank end mill holders and ER collet systems used in CNC and manual milling applications.

Installation Notes

Installation should be performed by a qualified machinist following shop safety protocols. Ensure the spindle is fully stopped and power is locked out before changing tooling. Seat the shank fully in the collet or holder and torque the retention nut to the tool holder specification. Verify runout with a dial indicator before commencing cuts, particularly given the small diameter of this tool where runout has a proportionally greater effect on tool life and finish quality.
