Harvey Tool 976131-C6 Square End Mill 7 Flute Solid Carbide

Product Description

The HARVEY TOOL 976131-C6 is a 7-flute solid carbide square end mill designed for high-performance milling in demanding machining applications. With a mill diameter of 0.0551 inches (1.4 mm) and a length of cut of 0.4331 inches (11 mm), this tool is built for precision work in tight tolerances. The 0.1575-inch (4 mm) shank diameter provides secure tool holding in standard collets. An AlTiN coating extends tool life in abrasive and hard materials by reducing heat buildup at the cutting edge. A variable helix geometry helps reduce chatter and improve surface finish across a range of cutting conditions.

This end mill is suited for mold and die work, medical component machining, and precision part production where small-diameter, multi-flute tooling is required. It is a single-end tool with right-hand cut and right-hand flute direction, making it compatible with conventional CNC machining centers and milling machines. The extended length of cut relative to diameter makes it appropriate for slotting, profiling, and finishing passes in harder workpiece materials where chip evacuation and rigidity are critical concerns.

Key Features

• 7-flute design increases feed rates and improves surface finish in harder materials
• AlTiN coating provides thermal resistance and extended tool life in abrasive alloys
• Variable helix reduces harmonic vibration and chatter during cutting
• Solid carbide construction delivers rigidity and wear resistance at small diameters
• Right-hand cut and right-hand flute direction for standard CNC spindle compatibility
• 0.4331-inch length of cut supports slotting and profiling operations

Compatibility

Designed for use in CNC milling machines and machining centers accepting a 0.1575-inch (4 mm) shank diameter. Suitable for use in standard ER collet systems and precision toolholders within that shank size range.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Use a calibrated torque wrench and the appropriate collet nut wrench when securing the tool in the holder to avoid over-tightening or under-tightening. Verify runout with a dial indicator after installation, as excessive runout on small-diameter carbide end mills accelerates breakage.
