Sgs 08641 Corner Radius End Mill Head 2 Flute Carbide

Product Description

The SGS 08641 is a solid micrograin carbide corner radius end mill head designed for precision metal removal in both roughing and finishing operations. Featuring 2 flutes with a right-hand spiral flute direction and right-hand cutting action, this end mill head delivers controlled chip evacuation and consistent surface finishes. The 0.003-inch corner radius reduces stress concentration at the cutting edge, extending tool life in demanding applications. A variable index and variable helix geometry help suppress chatter and vibration during aggressive cuts, making this tool suitable for high-productivity milling on tight-tolerance workpieces.

This end mill head is suited for use on CNC machining centers and manual mills in job shop, toolroom, and production environments. The centercutting design allows plunge entry, expanding its versatility across slotting, profiling, and pocket milling operations. With a 0.25-inch length of cut and compact overall dimensions, it is well matched to shallow-depth passes on ferrous and non-ferrous materials where a fine corner geometry is required. It is typically installed and operated by machinists and CNC programmers working with modular or exchangeable head tooling systems.

Key Features

• Solid micrograin carbide construction for improved wear resistance and edge retention
• 0.003-inch corner radius reduces edge chipping and extends tool life
• Variable helix and variable index geometry minimize chatter and harmonics
• Centercutting design enables direct plunge entry without a pre-drilled hole
• Right-hand spiral flutes promote efficient chip evacuation in standard spindle rotation
• Capable of roughing and finishing in a single tool, reducing changeovers

Compatibility

Designed as an OEM-style replacement or supplemental head for modular end mill tooling systems that accept compatible corner radius end mill heads with matching shank and head interface specifications.

Installation Notes

Installation and operation of this end mill head should be performed by a qualified machinist familiar with modular cutting tool systems. Ensure the spindle is fully stopped and the machine is locked out before mounting or removing the tool head. Confirm the mating shank interface is clean and free of chips or burrs before assembly to ensure proper seating and runout accuracy. Follow the tooling manufacturer torque guidelines for the specific head-locking mechanism used.
