Hertel C430L6250-C1 Roughing End Mill 5/8 in 4 Flute Carbide

Product Description

The HERTEL C430L6250-C1 is a single-end roughing end mill designed for aggressive material removal in milling applications. Built from micrograin solid carbide with a TiN coating, it combines wear resistance with edge retention across a range of workpiece materials. The chipbreaker geometry along the flute edges breaks chips into smaller segments, reducing heat buildup and cutting forces during heavy roughing passes. With a 5/8 inch diameter, 4 flutes, and a 2.25 inch length of cut, this tool suits production environments where metal removal rate is the priority. Licensed machinists and CNC programmers running vertical or horizontal machining centers are the primary users of this tool.

This end mill is suited for roughing operations on ferrous and non-ferrous metals in job shop and production machining environments. Its regular-length geometry makes it a practical choice for standard-depth pocketing, slotting, and profiling where extended reach is not required. The right-hand cut and right-hand flute direction are standard for conventional CNC milling setups. Center-cutting capability allows plunge entry without a pre-drilled pilot hole, adding flexibility in programming.

Key Features

• Micrograin solid carbide construction for high hardness and wear resistance
• TiN coating extends tool life and reduces friction during cutting
• Chipbreaker geometry reduces chip load and cutting forces during roughing
• Center-cutting design allows direct plunge entry
• Right-hand cut and right-hand flute direction for standard CNC compatibility
• 5/8 inch shank diameter matches mill diameter for direct collet or end mill holder clamping

Compatibility

Designed as an OEM-style replacement or direct-fit tooling option for standard 5/8 inch end mill holders, ER collet chucks, and milling machine spindles accepting a 5/8 inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's toolholding specifications. Ensure the spindle and tool changer are in a safe, powered-down or tool-change-ready state before inserting or removing the end mill. Use a calibrated torque wrench when tightening set-screw holders to avoid shank damage. Verify runout at the cutting edge with a dial indicator before commencing a roughing operation.
