Hertel C430-1000-C4 Roughing End Mill 1 in 4 Flute Carbide

Product Description

The HERTEL C430-1000-C4 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 wear resistance required for high-speed roughing passes on ferrous and non-ferrous metals. The chipbreaker geometry along the cutting edge breaks chips into shorter segments, reducing heat buildup and improving chip evacuation in deep-pocket and slotting applications. With a 1-inch cutting diameter, 1.5-inch length of cut, and 4-inch overall length, this tool is sized for standard roughing work in CNC machining centers and manual mills.

This end mill is suited for production and job-shop environments where roughing passes precede finish milling. It is used in applications involving steel, stainless, cast iron, and similar materials where chip load and tool life are critical factors. The right-hand cutting and right-hand flute direction make it compatible with conventional CNC spindle setups. Center-cutting capability allows plunge entry without a pre-drilled pilot hole. This tool is typically installed by machinists and CNC operators working in aerospace, automotive, mold-and-die, and general metalworking trades.

Key Features

• Micrograin solid carbide construction for extended tool life and edge retention
• TiCN coating improves surface hardness and reduces friction at the cutting edge
• Chipbreaker geometry promotes short chip formation and improves evacuation
• Center-cutting design allows direct plunge entry into workpiece material
• 4-flute configuration balances chip clearance with rigidity in roughing cuts
• Right-hand cut and right-hand flute direction for standard CNC spindle compatibility

Compatibility

Designed as an OEM-style replacement or direct-application roughing end mill for CNC machining centers and manual milling machines accepting a 1-inch straight shank tool holder.

Installation Notes

Installation is performed by a machinist or CNC operator. Ensure the spindle is fully stopped and the machine is in an e-stop or locked-out state before changing tooling. Seat the 1-inch shank fully into the tool holder and torque the retention mechanism per the tool holder manufacturer specification. Verify runout with a dial indicator before beginning a cut, as excessive runout accelerates edge wear and reduces surface finish quality.
