Hertel 2500487 Roughing End Mill 1/8 Inch 4 Flute Solid Carbide

Product Description

The HERTEL 2500487 is a single-end roughing end mill designed for aggressive material removal in milling operations. Built from micrograin solid carbide and coated with TiCN, it delivers the hardness and heat resistance needed for high-speed roughing passes. The 1/8 inch diameter, 4-flute configuration with an integrated chipbreaker breaks chips into manageable segments, reducing heat buildup and improving chip evacuation in the cut zone. Right-hand cut and right-hand flute direction are standard on this tool. Licensed machinists and CNC operators select this tool for demanding roughing work where tool life and cut stability are priorities.

This end mill is suited for use in vertical machining centers, CNC milling machines, and manual knee mills where a 1/8 inch diameter tool is required. The chipbreaker geometry makes it effective when cutting ferrous and non-ferrous metals that tend to produce long, stringy chips. The regular length designation and 3/4 inch length of cut keep the tool rigid at this small diameter, reducing deflection during heavy roughing passes. It is typically used in job shop, tool-and-die, and precision machining environments.

Key Features

• Micrograin solid carbide construction for extended tool life and wear resistance
• TiCN coating improves surface hardness and reduces friction during cutting
• Chipbreaker geometry promotes short chip formation and improved chip evacuation
• 4-flute, single-end design balances chip clearance with cut stability
• Center-cutting capable, allowing plunge entry into the workpiece
• Right-hand cut and right-hand flute direction, standard for most CNC applications

Compatibility

Designed as a standard 1/8 inch shank roughing end mill compatible with collet chucks, end mill holders, and shrink-fit toolholders that accept a 1/8 inch shank diameter in CNC and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Secure the tool in a clean, properly sized collet or end mill holder and torque the retention mechanism according to the toolholder manufacturer specifications. Inspect the shank and cutting edges for damage before each use. Never exceed the tool's rated speed and feed parameters for the workpiece material.
