Sandvik Coromant 7611646 Corner Radius End Mill Head

Product Description

The SANDVIK COROMANT 7611646 is a modular corner radius end mill head designed for precision milling operations in metalworking and machining applications. Built from solid carbide and finished with an AlTiN coating, this 4-flute head delivers hardness and heat resistance suited to demanding cutting environments. The head measures 1.50 mm (0.0591 inches) in mill diameter with a length of cut of 3.03 mm and features a 4.5 mm corner radius. It belongs to the CoroMill 316 series and uses a modular connection type, allowing it to mount onto compatible CoroMill 316 shanks and adapters. Right-hand spiral flute geometry supports efficient chip evacuation. Installation and use are intended for machining professionals and CNC operators.

This end mill head is suited to precision milling tasks in metalworking shops and machining centers handling tight tolerances and fine corner profiles. The small 1.50 mm mill diameter makes it appropriate for micro-milling and detail work on hardened or high-temperature alloy workpieces. Its non-center-cutting geometry means it is intended for side milling and profiling rather than plunge cutting. The CoroMill 316 modular system allows quick head changes without removing the shank from the spindle, reducing changeover time in production environments.

Key Features

• Solid carbide construction provides rigidity and wear resistance for hard material milling
• AlTiN coating improves heat resistance and tool life in dry or high-speed cutting conditions
• 4-flute spiral geometry supports smooth cutting and efficient chip evacuation
• 4.5 mm corner radius reduces stress concentration at the cutting edge for improved edge life
• Modular connection compatible with CoroMill 316 series shanks for fast head interchange
• Right-hand cutting direction for standard CNC spindle operation

Compatibility

Designed for use with the SANDVIK COROMANT CoroMill 316 modular end mill system. Compatible shanks and adapters within the CoroMill 316 series are required for proper installation.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician familiar with modular cutting tool systems. The machine spindle must be fully stopped and locked out before changing or seating the end mill head. Use the appropriate torque wrench and interface hardware specified for the CoroMill 316 connection to ensure proper clamping without over-torquing. This head is not center-cutting and should not be used for axial plunge operations.
