Hertel 750271 Square End Mill 3/4 in 4 Flute Solid Carbide

Product Description

The HERTEL 750271 is a solid carbide square end mill designed for precision milling operations in metal cutting and machining applications. Built from micrograin carbide and finished with a titanium nitride (TiN) coating, this single-end tool delivers consistent cutting performance and extended tool life across a range of ferrous and non-ferrous materials. The 750271 features a 4-flute, right-hand spiral geometry with a 30-degree helix angle, a 3/4 inch mill diameter, and a 1 inch length of cut. It is centercutting, allowing direct plunge entry. Licensed machinists and CNC programmers rely on tools like this for finish milling, profiling, and slotting in production and job-shop environments.

This end mill suits horizontal and vertical machining centers, knee mills, and manual milling machines where a 3/4 inch shank is required. The 3 inch overall length and 1 inch length of cut make it well suited for moderate-depth peripheral milling and side milling on steel, stainless, aluminum, and similar materials. The micrograin carbide substrate supports high-speed machining parameters. This tool is a single-end design, so it is replaced rather than flipped when worn. It is packaged and sold as a single unit.

Key Features

• Micrograin solid carbide substrate for rigidity and wear resistance
• TiN coating reduces friction and improves tool life in ferrous materials
• 4-flute, right-hand cut with right-hand spiral flute direction
• 30-degree helix angle promotes smooth chip evacuation
• Centercutting geometry allows direct plunge milling
• Single-end design with matched 3/4 inch shank and mill diameter

Compatibility

Designed for use in CNC machining centers, vertical mills, and manual milling machines accepting a 3/4 inch straight shank end mill holder or collet chuck.

Installation Notes

Installation and tool changes must be performed by a qualified machinist with the spindle fully stopped and the machine in a safe, locked-out state. Ensure the shank is clean and seated fully in the holder before torquing the collet or set screw to the tool holder manufacturer specification. Verify runout after installation before beginning a cut. Do not exceed the tool manufacturer recommended speeds and feeds for the workpiece material and coating type.
