Hertel 84511450 Roughing End Mill 2in 8-flute Cobalt Tialn

Product Description

The HERTEL 84511450 is a single-end roughing end mill designed for aggressive material removal in milling operations. Built from M42 cobalt high-speed steel and coated with TiAlN for heat resistance, this tool handles tough ferrous materials and interrupted cuts that would wear down standard HSS tooling. The 2-inch cutting diameter and coarse pitch geometry work together to evacuate large chips quickly, reducing heat buildup and extending tool life between regrinds. With 8 flutes and a right-hand cutting and flute direction, it delivers consistent stock removal in roughing passes across a wide range of milling setups.

This end mill is suited for heavy roughing applications on vertical and horizontal milling machines as well as CNC machining centers. The 6-inch length of cut allows deep-cavity and deep-shoulder passes without requiring tool changes. Single-end construction makes it a go-to for production shops and maintenance machining environments where cobalt tooling is specified for its toughness and red hardness. It is not center-cutting, so it requires a pre-drilled or pre-milled entry point when plunging is part of the operation.

Key Features

• M42 cobalt construction provides superior red hardness and toughness over standard M2 HSS
• TiAlN coating improves heat resistance and extends tool life in dry and semi-dry cutting conditions
• 2-inch cutting diameter with 8 flutes for high material removal rates on roughing passes
• 6-inch length of cut enables deep-shoulder and deep-cavity milling in a single setup
• Coarse pitch flute geometry promotes aggressive chip evacuation and reduces chip re-cutting
• Right-hand cut and right-hand helix; not center-cutting — requires pre-milled entry for plunge operations

Compatibility

Designed as an OEM-style roughing end mill for use in standard 2-inch straight-shank or collet tool holders on vertical mills, horizontal mills, and CNC machining centers capable of accepting a 2-inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the spindle is fully powered down and locked out before inserting or removing the end mill from the tool holder. Seat the shank fully in the holder to the manufacturer-recommended engagement depth before torquing set screws or tightening collet nuts. Verify tool runout with a dial indicator before commencing the cut, as excessive runout on a large-diameter roughing tool accelerates premature wear and can cause chatter or workpiece damage.
