Hertel 750086 Square End Mill 5/8 in 2 Flute Solid Carbide

Product Description

The HERTEL 750086 is a solid carbide square end mill designed for precise milling operations in ferrous and non-ferrous materials. With a 5/8 inch cutting diameter and a 3 inch length of cut, it handles deep slotting, profiling, and peripheral milling in a single setup. The micrograin carbide construction provides edge retention and resistance to wear under continuous cutting loads. The 30-degree helix angle promotes efficient chip evacuation and reduces cutting forces. This tool is installed and used by machinists and CNC operators in job shop, production, and toolroom environments.

This end mill is suited for general-purpose milling in a wide range of materials including steel, cast iron, aluminum, and plastics. The single-end, center-cutting design allows both plunge and ramp entry. With a 6 inch overall length and a 5/8 inch shank diameter, it fits standard ER and side-lock toolholders used on vertical machining centers and manual knee mills. The bright uncoated finish makes it a strong choice for applications where coating adhesion to the workpiece is a concern, such as certain aluminum alloys.

Key Features

• Solid micrograin carbide construction for superior wear resistance and edge retention
• 5/8 inch cutting diameter with 3 inch length of cut for deep milling passes
• 30-degree right-hand spiral helix promotes efficient chip evacuation
• Center-cutting capable — supports plunge and ramp entry
• Bright uncoated finish suitable for aluminum and non-ferrous applications
• Right-hand cutting direction compatible with standard CNC and manual milling setups

Compatibility

Designed as a standard-shank solid carbide square end mill for use in 5/8 inch ER collet chucks, Weldon side-lock holders, and hydraulic toolholders on vertical machining centers and manual mills.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is in a safe lockout state before loading or removing the tool. Seat the shank to the full recommended engagement depth in the toolholder before tightening to prevent tool pullout. Verify runout with a dial indicator after clamping, as excessive runout accelerates edge wear and reduces surface finish quality.
