Hertel 750736 Square End Mill 5/16 in 2 Flute Solid Carbide

Product Description

The HERTEL 750736 is a solid carbide square end mill designed for precision milling in demanding metalworking applications. Built from micrograin carbide and coated with AlTiN (aluminum titanium nitride), it delivers strong heat and wear resistance at elevated cutting temperatures. The 2-flute geometry with a 30-degree helix angle promotes efficient chip evacuation, reducing heat buildup and improving surface finish. At 5/16 inch diameter with a 1/2 inch length of cut and 2 inch overall length, it suits tight-tolerance profiling, slotting, and contouring operations. Centercutting capability allows direct plunge entry into workpieces without a pilot hole.

This end mill is suited for milling ferrous and non-ferrous metals, hardened steels, stainless, and high-temperature alloys where AlTiN coating provides a performance advantage over uncoated carbide. Typical applications include CNC machining centers, vertical mills, and manual knee mills used in tool and die, aerospace component, and general precision machining environments. The right-hand cut and right-hand flute direction match standard spindle configurations. It is installed and used by machinists and CNC operators in production and job-shop settings.

Key Features

• AlTiN coating for high heat resistance and extended tool life in hard and abrasive materials
• Micrograin solid carbide substrate for rigidity and edge sharpness
• 2-flute design with 30-degree helix angle for efficient chip evacuation in slotting and profiling
• Centercutting geometry allows direct plunge entry without pre-drilling
• Right-hand cut and right-hand flute direction for standard CNC and manual mill spindles
• Consistent 5/16 inch shank matches 5/16 inch diameter for straightforward collet setup

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide end mill for standard 5/16 inch collets and end mill holders on CNC machining centers and manual vertical mills.

Installation Notes

Installation is performed by a machinist or CNC operator. Ensure the spindle is fully stopped and locked out before changing tooling. Seat the shank fully into a clean, burr-free collet or end mill holder and torque the retention nut per the toolholder manufacturer specification. Inspect the cutting edges for chips or coating damage before each use, as carbide tooling is brittle and should not be dropped or struck against hard surfaces.
