Hertel 89319057 Square End Mill 11/16 in 3 Flute Carbide

Product Description

The HERTEL 89319057 is a solid carbide square end mill designed for precision milling in metal cutting and machining applications. With an 11/16 inch cutting diameter, a 1-3/8 inch length of cut, and a 3/4 inch shank diameter, this tool delivers the rigidity and dimensional accuracy that machinists demand in production environments. The micrograin carbide substrate supports sharp edge retention across a range of workpiece materials. The 30-degree right-hand helix promotes efficient chip evacuation, and the centercutting geometry allows plunge entry as well as conventional profiling. This is a single-end, uncoated tool intended for use in CNC machining centers and manual mills by qualified machinists and tooling professionals.

This end mill is suited for general-purpose milling operations including slotting, profiling, and peripheral milling in shop and production settings. The regular length configuration and 4 inch overall length make it a practical fit for standard toolholders and collet chucks. The right-hand cutting direction and right-hand flute direction align with conventional spindle rotation on most vertical machining centers. The uncoated bright finish is appropriate for applications where dry cutting or certain cutting fluids are used and a base carbide substrate is preferred over coated alternatives.

Key Features

• Solid micrograin carbide construction for edge retention and rigidity
• Centercutting design allows plunge milling in addition to side milling
• 30-degree helix angle promotes smooth chip flow and reduced chatter
• 3 flutes with right-hand cut and right-hand flute direction
• Uncoated bright finish suitable for dry or fluid-assisted machining
• Regular length at 4 inches OAL for compatibility with standard toolholding setups

Compatibility

Designed as a standard-shank solid carbide square end mill with a 3/4 inch shank diameter, suitable for use in collet chucks, end mill holders, and shrink-fit toolholders that accept 3/4 inch shanks on CNC machining centers and manual mills.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and the tool is seated to the correct gauge length in the holder before tightening. Use a torque wrench on set-screw holders and verify runout with an indicator before beginning a cut. Follow the machine manufacturer and tooling supplier recommendations for speeds and feeds based on workpiece material.
