Hertel 750306 Square End Mill 5/8 in 4 Flute Solid Carbide Ticn

Product Description

The HERTEL 750306 is a solid carbide square end mill designed for precision milling operations in metalworking and machining environments. It features a 5/8 inch diameter with a 3 inch length of cut and a 6 inch overall length, placing it in the extra long category for extended reach applications. The micrograin carbide substrate is coated with TiCN (titanium carbonitride) for improved wear resistance and surface hardness. With 4 flutes and a 30-degree helix angle, it is suited for finishing and semi-finishing passes in ferrous and non-ferrous materials. Installation and operation are handled by machinists and CNC operators in machine shop environments.

This end mill is built for applications requiring deep axial cuts or extended reach into pockets, slots, and contoured surfaces. The extra long length type makes it appropriate for mold work, deep cavity milling, and workpiece setups where standard-length tooling cannot reach. The centercutting design allows plunge entry, expanding its use in pocket milling operations. The right-hand cut and right-hand spiral flute configuration match the standard spindle direction of most vertical and horizontal machining centers. No chipbreaker geometry is present, keeping the cutting profile clean for finishing work.

Key Features

• Solid micrograin carbide substrate for rigidity and dimensional stability under load
• TiCN coating increases surface hardness and extends tool life in abrasive materials
• 4-flute, 30-degree helix design balances chip evacuation with surface finish quality
• Centercutting capability allows direct plunge entry without pre-drilling
• Extra long 6 inch overall length with 3 inch length of cut for deep-reach applications
• Right-hand cut and right-hand spiral flute for standard CNC spindle compatibility

Compatibility

Designed as a standard shank solid carbide end mill compatible with 5/8 inch collets, end mill holders, and shrink-fit toolholders used in CNC machining centers and manual knee mills.

Installation Notes

This tool should be installed by a qualified machinist following the toolholder manufacturer torque and runout specifications. Confirm spindle direction is right-hand before engaging the cut. Inspect the collet or toolholder for wear and contamination before seating the shank to maintain concentricity. Follow your facility safety protocols and machine guarding requirements during setup and operation.
