Value Collection 720-1660 Square End Mill 1/8 in 2 Flute Hss

Product Description

The VALUE COLLECTION 720-1660 is a double-end, two-flute square end mill designed for material removal in machining operations. Manufactured from M2 high speed steel with a bright/uncoated finish, it carries a 1/8 inch cutting diameter and a 3/4 inch length of cut. The 30-degree right-hand spiral helix promotes efficient chip evacuation during cuts. At 3-1/8 inches overall length with a 3/16 inch shank diameter, this tool fits standard collets and toolholders sized for that shank. The double-end configuration extends usable tool life, making it a practical option for shops running repeated operations on steel, stainless steel, cast iron, and high-temperature alloys.

This end mill is suited for milling, slotting, and profiling operations on ferrous metals and high-temp alloys in both manual and CNC machining environments. Its centercutting geometry allows plunge entry, giving machinists flexibility in programming tool paths. The long-series length type provides added reach for deeper setups where standard-length tooling falls short. It is appropriate for job shop use, production machining, and tool room applications where a reliable fractional-inch HSS end mill is needed.

Key Features

• M2 high speed steel construction for cutting steel, stainless steel, cast iron, and high-temp alloys
• Double-end design extends usable tool life from a single cutter
• 30-degree right-hand helix for efficient chip evacuation
• Centercutting capable — supports direct plunge entry
• Bright/uncoated finish suitable for general-purpose ferrous machining
• Long-series length type for added reach in deeper setups

Compatibility

Designed for use in standard collets and toolholders accepting a 3/16 inch shank diameter. Primary workpiece materials include steel, stainless steel, cast iron, and high-temperature alloys (material codes P, M, K, S).

Installation Notes

Install in a collet or end mill holder rated for a 3/16 inch shank and ensure the holder is fully tightened before operation. Confirm spindle runout is within acceptable limits before engaging the cut, as runout accelerates wear on small-diameter tooling. Always power down and lock out the machine spindle before changing or inspecting tooling. Follow shop-specific speeds and feeds for M2 HSS based on the workpiece material being cut.
