Value Collection 722-2020 Square End Mill 7/32 in 2 Flute Hss

Product Description

The VALUE COLLECTION 722-2020 is a double-end, square-profile end mill designed for milling operations in ferrous and high-temperature alloy materials. Manufactured from M2 high speed steel with a TiN (titanium nitride) coating, it delivers extended tool life in demanding cutting environments. The cutter measures 7/32 inch (0.2188 inches) in diameter with a 1/2 inch length of cut, a 3/8 inch shank diameter, and a 3-1/8 inch overall length. With 2 flutes, a 30-degree helix angle, and a right-hand cut and flute configuration, this end mill suits finish and semi-finish passes on steel, stainless steel, cast iron, and high-temperature alloys. Licensed machinists and tool-and-die technicians are the primary users of this tool class.

This end mill is suited for vertical machining centers, knee mills, and manual milling machines where a fractional-inch, regular-length tool is appropriate. The double-end design allows the operator to flip the tool when one end wears, effectively doubling usable tool life from a single piece. The centercutting geometry enables both plunge and peripheral cutting, making it versatile for slot milling, profiling, and step milling applications in steel, stainless steel, cast iron, and high-temperature alloy workpieces.

Key Features

• M2 high speed steel construction for toughness and wear resistance in ferrous materials
• TiN coating reduces friction and extends tool life compared to uncoated HSS
• Double-end design provides two usable cutting ends per tool
• Centercutting geometry supports plunge, slot, and peripheral milling
• 30-degree spiral flute helix promotes efficient chip evacuation
• Right-hand cut and right-hand flute for use in standard spindle rotation

Compatibility

Suitable for milling steel, stainless steel, cast iron, and high-temperature alloys. Compatible with standard 3/8 inch collets, end mill holders, and milling chucks on vertical and horizontal milling machines.

Installation Notes

Installation is performed by machinists or machine operators using a standard collet or end mill holder sized for a 3/8 inch shank. Ensure the spindle is fully de-energized and locked out before inserting or removing the tool. Seat the shank to the full recommended grip length in the holder and torque the collet nut per the tool-holder manufacturer specification. Verify runout with a dial indicator before beginning a cut, as excessive runout accelerates edge wear and reduces surface finish quality.
