Hertel EM99924521 Ball End Mill 0.1875 in 4 Flute Carbide

Product Description

The HERTEL EM99924521 is a solid carbide ball end mill designed for precise milling operations in metalworking and machining applications. With a 0.1875 inch mill diameter and a 0.3125 inch length of cut, this single-end tool is built for profiling, contouring, and finishing passes on hardened and abrasion-resistant workpiece materials. The AlTiN coating provides high heat resistance and extended tool life in ferrous and hard alloy cutting. A 30-degree helix angle and 4-flute geometry promote efficient chip evacuation and a smooth surface finish. This tool is intended for use by machinists and tool and die professionals working on CNC machining centers and manual mills.

This ball end mill suits applications in mold and die work, aerospace component machining, and precision part manufacturing where tight tolerances and fine surface finishes are required. The micrograin carbide substrate supports rigidity and edge retention in demanding cutting conditions. The right-hand cutting and right-hand flute direction make it compatible with standard spindle rotation on conventional CNC and manual milling equipment. Its compact diameter makes it well suited for fine detail work and slotting in confined geometries.

Key Features

• AlTiN coating for high-temperature resistance and extended tool life in ferrous materials
• 4-flute, single-end design with 30-degree helix for efficient chip flow and surface finish quality
• Micrograin solid carbide construction for rigidity and edge retention
• Right-hand cutting and right-hand flute direction for standard CNC spindle compatibility
• 0.1875 inch shank diameter with 2 inch overall length for straightforward toolholder setup

Compatibility

Designed as an OEM-style solid carbide ball end mill for use in standard CNC machining centers and manual milling machines accepting a 0.1875 inch shank diameter collet or end mill holder.

Installation Notes

Installation is performed by qualified machinists or toolroom personnel. Secure the shank in a properly sized collet or end mill holder and torque to the toolholder manufacturer specifications before use. Verify spindle runout is within acceptable limits to protect the cutting edge and maintain dimensional accuracy. Always power down and lock out the machine spindle before changing or inspecting tooling.
