Value Collection 720-1618 Square End Mill 11/64 in 2 Flute Hss

Product Description

The VALUE COLLECTION 720-1618 is a double-end, two-flute square end mill designed for precision material removal in metalworking and machining applications. Built from M2 high speed steel with a bright/uncoated finish, it measures 11/64 inches (0.1719 inches) in diameter with a 1/4 inch length of cut and a 2 inch overall length. The 30-degree helix angle promotes efficient chip evacuation and smooth cutting action. This stub-length end mill is center-cutting, allowing for direct plunge entry, and cuts in a right-hand direction with right-hand spiral flutes. It suits shops and machinists who need a reliable small-diameter tool for tight-tolerance work.

This end mill is suited for milling operations on steel, stainless steel, cast iron, and high-temperature alloys. Its small 11/64 inch diameter makes it appropriate for slotting, profiling, and detail work in areas where larger tools cannot reach. The double-end design provides two usable cutting ends, extending tool life and reducing per-job tooling cost. Typical applications include manual milling machines, CNC machining centers, and toolroom work requiring fractional inch tooling.

Key Features

• M2 high speed steel construction for durability across ferrous and high-temp alloy workpieces
• Double-end design provides two cutting ends per tool
• Center-cutting capability allows direct plunge milling without pre-drilling
• 30-degree helix angle for efficient chip flow and reduced cutting force
• Bright/uncoated finish — compatible with cutting fluids and standard lubrication
• Stub length for added rigidity in small-diameter applications

Compatibility

Designed as a fractional inch, double-end square end mill for use in standard end mill holders and collet chucks accepting a 3/16 inch shank diameter. Suitable for steel, stainless steel, cast iron, and high-temperature alloy workpieces per primary workpiece material classifications P, M, K, and S.

Installation Notes

Installation is performed by qualified machinists using an appropriate collet chuck or end mill holder sized for a 3/16 inch shank. Ensure the machine spindle is fully stopped and locked out before changing or seating the tool. Verify runout with a dial indicator after seating to avoid premature wear on this small-diameter cutter. Follow shop-standard feeds, speeds, and cutting fluid practices for the workpiece material being machined.
