Hertel 84512763 Roughing End Mill 1 in 5 Flute Cobalt

Product Description

The HERTEL 84512763 is a single-end roughing end mill designed for high-metal-removal operations on ferrous and hard alloy workpieces. Built from M42 cobalt high-speed steel and coated with TiAlN for extended tool life at elevated cutting temperatures, this end mill features five fine-pitch flutes that break chips aggressively while maintaining a smooth cutting action. With a 1-inch mill diameter, a 2-inch length of cut, and a 4.5-inch overall length, it is suited for slotting, profiling, and roughing passes where rapid stock removal is the priority. Licensed machinists and CNC operators are the primary users.

This end mill fits standard 1-inch straight-shank toolholders and is appropriate for use on vertical and horizontal milling machines as well as CNC machining centers. It is configured for right-hand cutting and right-hand flute direction, making it compatible with conventional spindle rotation. The fine-pitch five-flute geometry is best applied in roughing passes on steel and stainless alloys where aggressive chip evacuation is needed before a finishing pass.

Key Features

• M42 cobalt construction for heat and wear resistance in demanding cuts
• TiAlN coating extends tool life at high cutting temperatures
• Five fine-pitch flutes for aggressive chip breaking and fast metal removal
• Center-cutting geometry allows plunge entry into the workpiece
• Right-hand cut and right-hand flute direction for standard spindle setups
• 1-inch shank diameter matches 1-inch straight-shank collets and milling chucks

Compatibility

Designed for use in standard 1-inch straight-shank toolholders on vertical mills, horizontal mills, and CNC machining centers running right-hand spindle rotation.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and power is locked out before changing tooling. Seat the shank fully in the toolholder and torque the retention mechanism according to the toolholder manufacturer specification. Confirm runout with a dial indicator before beginning a cut, as excessive runout accelerates wear on cobalt end mills.
