Hertel 2500504 Roughing End Mill 5/16 in 4 Flute Carbide

Product Description

The HERTEL 2500504 is a single-end roughing end mill designed for aggressive material removal in milling applications. Built from micrograin solid carbide and coated with titanium nitride (TiN), it delivers extended tool life and improved wear resistance under heavy cutting conditions. The 5/16-inch diameter tool features four flutes with a chipbreaker geometry that breaks chips into smaller segments, reducing heat buildup and cutting forces during extended passes. Center-cutting capability allows plunge entry directly into the workpiece. This tool is used by machinists and tool-and-die professionals in CNC and manual milling operations.

The 2500504 is suited for roughing passes on ferrous and non-ferrous metals in job shop, production, and maintenance machining environments. With a 1-1/8-inch length of cut and a 3-inch overall length on a 5/16-inch straight shank, it fits standard collet and end mill holders in vertical and horizontal milling setups. The right-hand cut and right-hand flute direction are standard for conventional and climb milling on most CNC machining centers and knee mills.

Key Features

• Chipbreaker geometry reduces chip load and cutting forces during roughing passes
• Micrograin solid carbide construction for rigidity and wear resistance
• TiN coating extends tool life and reduces friction at the cutting edge
• Center-cutting design allows direct plunge entry into the workpiece
• 4-flute configuration balances chip evacuation with surface finish during roughing
• Right-hand cut and right-hand flute for compatibility with standard spindle rotation

Compatibility

Designed as an OEM-style replacement or direct-use roughing end mill for standard 5/16-inch collets and end mill holders used in CNC machining centers, knee mills, and similar milling equipment.

Installation Notes

Installation should be performed by a qualified machinist familiar with tool holding and runout requirements. Ensure the spindle is fully stopped and locked before inserting or removing the tool from the holder. Verify shank seating depth and holder torque according to the tool holder manufacturer specifications. Inspect the cutting edges and chipbreaker geometry for damage before each use, as carbide tools are brittle and can chip if mishandled or dropped.
