Hertel 2500483 Roughing End Mill 1/8 in 4 Flute Carbide

Product Description

The HERTEL 2500483 is a single-end roughing end mill designed for aggressive material removal in milling applications. Built from micrograin solid carbide and coated with TiCN, this tool delivers hardness and wear resistance suited for ferrous and non-ferrous metals. The chipbreaker geometry along the 4-flute cutting edge breaks chips into smaller segments, reducing heat buildup and load on the spindle. The 1/8 inch diameter and 0.25 inch length of cut make it well suited for tight-tolerance profiling and slotting passes. Center-cutting capability allows plunge entry without a pre-drilled pilot hole. Right-hand cut and right-hand flute direction follow standard CNC machining conventions.

This end mill is intended for use in CNC machining centers and manual knee mills performing roughing passes in aluminum, steel, stainless, and similar materials. The 1/8 inch shank fits standard ER collet systems and toolholders rated for that diameter. The regular-length geometry suits workpieces that do not require extended reach. It is a practical choice for prototype shops, production facilities, and tool rooms where small-diameter roughing is a recurring operation. Machinists and CNC programmers specify tools like this when chipload management and tool life are priorities over finish quality in the roughing stage.

Key Features

• Micrograin solid carbide construction for hardness and edge retention
• TiCN coating improves wear resistance and reduces surface friction
• Chipbreaker geometry reduces chip length and spindle load during roughing
• Center-cutting design allows direct plunge entry
• 4 flutes with right-hand cut and right-hand helix for standard CNC compatibility
• Shank diameter tolerance of +0.0001 to -0.0004 inches for precise toolholder fit

Compatibility

Designed as an OEM-style replacement or direct-use roughing end mill for CNC machining setups requiring a 1/8 inch shank, single-end, 4-flute chipbreaker tool in a regular-length configuration.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Secure the shank in a clean, properly sized collet or end mill holder and torque the retention system according to the toolholder manufacturer specifications. Verify runout with a dial indicator before beginning a cut. Always confirm spindle speed and feedrate parameters match the material being machined and the tool diameter before engaging the cut.
