Value Collection 720-1646 Square End Mill 5/32 in 2 Flute Hss

Product Description

The VALUE COLLECTION 720-1646 is a double-end, two-flute square end mill designed for precision milling operations in metalworking applications. Manufactured from M2 high speed steel with a bright/uncoated finish, it delivers reliable cutting performance across a range of ferrous and high-temperature materials. The mill measures 5/32 inch (0.1563 inch) in diameter with a 7/16 inch (0.4375 inch) length of cut and a 2-1/4 inch overall length. The 30-degree helix angle promotes smooth chip evacuation and reduces cutting forces during operation. The double-end configuration provides two usable cutting ends, extending tool life between replacements. Licensed machinists, tool-and-die workers, and maintenance mechanics are the typical end users.

This end mill is suited for slotting, profiling, and light contouring operations on steel, stainless steel, cast iron, and high-temperature alloys. The right-hand cut and right-hand flute spiral are standard for conventional milling setups on knee mills, CNC machining centers, and manual milling machines. The 3/16 inch shank diameter fits standard collets and end mill holders in that size range. It is a regular-length tool, making it appropriate for general-purpose work where extended reach is not required.

Key Features

• Double-end design provides two cutting ends per tool, increasing value per tool
• M2 high speed steel construction handles steel, stainless steel, cast iron, and high-temp alloys
• 30-degree helix angle promotes efficient chip evacuation and smooth cutting action
• Center-cutting geometry allows plunge entry into workpiece material
• Bright/uncoated finish suitable for a wide range of general metalworking applications
• Right-hand cut and right-hand spiral for compatibility with standard milling setups

Compatibility

Designed as a general-purpose replacement or stock end mill for use in standard 3/16 inch collets and end mill holders on manual knee mills and CNC machining centers performing operations on steel, stainless steel, cast iron, and high-temperature alloys.

Installation Notes

Installation is performed by machinists or tool-and-die professionals. Always ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the 3/16 inch shank fully into the collet or end mill holder and torque the retention hardware per the machine manufacturer's specifications. Inspect cutting edges for chips or wear before mounting, as a damaged cutting edge on a double-end tool may be resolved by reversing to the unused end.
