Hertel EM250048 Ball End Mill 0.75 in 4 Flute Solid Carbide

Product Description

The HERTEL EM250048 is a solid carbide ball end mill designed for precision milling operations in metal-cutting applications. With a 0.75-inch cutting diameter and four flutes, this single-end tool delivers efficient chip evacuation and smooth surface finishes on hardened and high-strength workpiece materials. The AlTiN (aluminum titanium nitride) coating provides elevated heat resistance, extending tool life in demanding dry or semi-dry cutting conditions. A 30-degree helix angle balances cutting forces and promotes stable performance across a range of feed rates. Machinists and CNC programmers working in aerospace, die and mold, and general metalworking will find this tool suited to contouring, profiling, and 3D surface work.

This ball end mill is intended for use in vertical machining centers, horizontal mills, and CNC milling machines capable of holding a 0.75-inch straight shank. The 1.5-inch length of cut supports moderate-depth cavity work and profile passes. Right-hand cutting and right-hand flute direction make this tool compatible with standard spindle rotation on conventional machining equipment. It is a single-end tool, so inspection of the cutting end before each use is recommended to verify edge integrity.

Key Features

• Solid carbide construction with micrograin substrate for rigidity and wear resistance
• AlTiN coating extends tool life in high-temperature cutting of alloy steels and hardened materials
• 4-flute geometry improves surface finish and material removal rate on ferrous workpieces
• 30-degree helix angle reduces cutting forces and supports stable engagement
• Right-hand cut and right-hand flute direction for standard CNC spindle compatibility
• Single-end design with 0.75-inch shank for direct collet or end mill holder mounting

Compatibility

Designed as a direct-fit replacement or standard tooling selection for CNC machining centers and manual mills accepting a 0.75-inch shank end mill holder or collet chuck.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before inserting or removing the tool. Seat the shank fully in the collet or end mill holder to the recommended engagement depth per the toolholder manufacturer. Verify runout with a dial indicator after clamping before beginning any cutting operation.
