Hertel 2500492 Roughing End Mill 3/16 Inch 4 Flute Carbide

Product Description

The HERTEL 2500492 is a single-end roughing end mill designed for aggressive material removal in milling operations. Built from micrograin solid carbide and coated with TiN (Titanium Nitride), this tool delivers extended wear resistance and consistent cutting performance. It features a 3/16 inch diameter with a 5/8 inch length of cut and a 2 inch overall length. The chipbreaker geometry reduces cutting forces and chip load, making it well suited for hogging out material in a single pass. Right-hand cutting and right-hand flute direction are standard. This tool is installed and operated by machinists and CNC operators working in job shops, tool rooms, and production environments.

The HERTEL 2500492 is intended for use in vertical machining centers, CNC mills, and manual knee mills where a compact, small-diameter roughing tool is needed. The 3/16 inch shank diameter matches the cutter diameter, allowing direct chuck or collet holding without a reducer. The regular length profile makes it a straightforward choice for shallow-to-moderate depth pockets, slots, and profiling passes. It is center-cutting, allowing direct plunge entry into the workpiece where required.

Key Features

• Micrograin solid carbide construction for rigidity and wear resistance
• TiN coating extends tool life and reduces friction at the cutting edge
• Chipbreaker geometry lowers cutting forces and improves chip evacuation
• Center-cutting design allows direct plunge milling
• Right-hand cut, right-hand flute, single-end configuration
• Shank diameter tolerance of +0.0001 to -0.0004 inches for precise collet fit

Compatibility

Designed as a direct-fit replacement or new installation in standard 3/16 inch collets, end mill holders, and chucks used on CNC and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Always power down and lock out the spindle before mounting or removing the tool. Ensure the collet or holder is clean and free of chips before seating the shank. Verify runout with a dial indicator before beginning a cut to confirm proper seating and avoid premature tool wear.
