Value Collection 720-1640 Square End Mill 7/64 in 2 Flute Hss

Product Description

The VALUE COLLECTION 720-1640 is a double-end, two-flute square end mill designed for precision material removal in metalworking applications. Built from M2 high speed steel with a bright/uncoated finish, this tool measures 0.1094 inches in cutting diameter with a 0.3281-inch length of cut and a 2.25-inch overall length. The 30-degree helix angle promotes efficient chip evacuation and smooth cutting action across a range of ferrous materials. Center-cutting capability allows the tool to plunge directly into a workpiece, adding versatility on the mill. At 0.06 pounds, it is lightweight and suited for close-tolerance work in tight setups.

This end mill is intended for use in vertical milling machines and machining centers where fractional-inch tooling is standard. The double-end configuration provides two usable cutting ends, extending tool life and reducing downtime during production runs. Primary workpiece materials include steel, stainless steel, cast iron, and high-temperature alloys, making this tool applicable across general machining, tool-and-die, and maintenance-repair operations where a small-diameter cutter is required.

Key Features

• M2 high speed steel construction for durability across ferrous and high-temp alloy materials
• Double-end design provides two cutting ends per tool
• 30-degree right-hand helix angle for efficient chip evacuation
• Center-cutting geometry allows direct plunge entry into workpiece
• Bright/uncoated finish compatible with a wide range of cutting fluids and dry cutting
• Spiral flute type with right-hand cutting direction for standard mill setups

Compatibility

Designed for use with standard 3/16-inch collets or end mill holders on vertical milling machines and CNC machining centers. Suitable for cutting steel, stainless steel, cast iron, and high-temperature alloys per material codes P, M, K, and S.

Installation Notes

Installation should be performed by a qualified machinist familiar with toolholder torque requirements and runout specifications. Ensure the machine spindle is fully stopped and locked before inserting or removing the end mill. Verify collet size matches the 0.1875-inch shank diameter before securing the tool. Follow the machine manufacturer's recommended speeds and feeds for M2 high speed steel tooling when cutting the intended workpiece materials.
