Hertel EM250064 Ball End Mill 1 in 4 Flute Altin Carbide

Product Description

The HERTEL EM250064 is a single-end ball end mill designed for high-performance milling in demanding machining environments. Built from micrograin solid carbide and coated with AlTiN (aluminum titanium nitride), this tool handles hard materials, high cutting temperatures, and abrasive workpieces that would wear down standard tooling quickly. The 1 inch cutting diameter pairs with a 1.5 inch length of cut and a 4-flute geometry to deliver strong material removal rates and a quality surface finish in ferrous and non-ferrous applications. The 30-degree right-hand helix promotes efficient chip evacuation and reduces cutting forces during full-depth passes.

This ball end mill is suited for CNC machining centers and manual mills in job shop, tool-and-die, mold making, and general production environments. The ball nose profile makes it a primary choice for 3D contouring, profiling, and finishing passes on complex surfaces. With a 1 inch shank diameter matching the cutting diameter, the tool seats directly in standard end mill holders, collet chucks, or hydraulic tool holders sized for 1 inch straight shanks. It is installed and operated by machinists and CNC programmers in metalworking and fabrication shops.

Key Features

• Micrograin solid carbide substrate provides high hardness and wear resistance at elevated cutting speeds
• AlTiN coating extends tool life in hard steels, stainless, and heat-resistant alloys by increasing surface hardness and thermal stability
• 4-flute design balances chip clearance with core strength for aggressive material removal
• 30-degree right-hand helix promotes smooth chip flow and reduces chatter
• Ball nose geometry enables 3D contouring, ramping, and profiling operations
• Single-end configuration with a 1 inch shank fits standard 1 inch bore toolholders directly

Compatibility

Designed as an OEM-style solid carbide ball end mill for use in CNC machining centers and manual milling machines equipped with 1 inch straight-shank toolholders.

Installation Notes

Installation is performed by qualified machinists following standard toolholding procedures. Secure the shank fully within the holder to the recommended minimum engagement depth before tightening. Verify runout at the spindle before initiating a cut, as excessive runout will accelerate wear and reduce surface finish quality. Follow all machine guarding and PPE requirements per shop safety standards when handling and setting carbide tooling.
