Hertel 750573 Square End Mill 9/32 in 4 Flute Carbide

Product Description

The HERTEL 750573 is a solid carbide square end mill designed for precision milling operations in metal fabrication and machining environments. Built from micrograin carbide, it delivers the hardness and wear resistance required for cutting ferrous and non-ferrous materials. The tool measures 0.2813 inches (9/32 inch) in cutting diameter with a 5/16-inch shank diameter and a 2-1/2-inch overall length. A 30-degree helix angle and four spiral flutes promote efficient chip evacuation and stable cutting at moderate-to-high feed rates. This is an uncoated, centercutting end mill capable of plunge entry, making it suitable for slotting, profiling, and pocketing applications.

The 750573 fits standard CNC machining centers and manual mills using ER collets or standard end mill holders accepting a 5/16-inch shank. With a 1-1/4-inch length of cut and a regular-length classification, it handles typical depth requirements in ferrous metals, aluminum, and plastics. Right-hand cut and right-hand flute orientation make this a conventional-rotation tool compatible with standard spindle configurations. It is well-suited for job shops, tool rooms, and production machining environments where consistent dimensional accuracy is required.

Key Features

• 0.2813-inch (9/32 inch) cutting diameter with a 5/16-inch shank
• 1-1/4-inch length of cut supports slotting and profiling at standard depths
• Four spiral flutes with a 30-degree helix angle for efficient chip removal
• Centercutting design allows direct plunge entry into workpiece material
• Right-hand cut and right-hand flute, uncoated finish

Compatibility

Designed as a direct-fit replacement or standard tooling selection for CNC machining centers and manual mills accepting a 5/16-inch shank end mill in ER collet chucks or end mill holders.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Secure the shank to the full recommended grip depth in the collet or holder to prevent pullout under cutting loads. Verify runout with a dial indicator after clamping before initiating any cut.
