Value Collection 720-1644 Square End Mill 9/64 in 2 Fl Hss

Product Description

The VALUE COLLECTION 720-1644 is a double-end, two-flute square end mill designed for precision milling in metal fabrication and machine shop applications. Made from M2 grade high speed steel with a bright uncoated finish, it measures 0.1406 inches (9/64 inches) in cutting diameter with a 13/32-inch length of cut and a 2-1/4-inch overall length. The 30-degree helix angle promotes smooth chip evacuation, and the centercutting geometry allows plunge entry as well as peripheral milling. This tool is installed and operated by machinists, toolroom technicians, and skilled CNC or manual mill operators.

This end mill is suited for milling operations on steel, stainless steel, cast iron, and high-temperature alloys. The double-end configuration doubles the service life per tool, making it a practical choice for production environments and job shops running moderate-volume work. The 3/16-inch shank diameter fits standard collets and end mill holders on both manual knee mills and CNC machining centers. It is intended for regular-length reach applications without coolant-through capability.

Key Features

• M2 high speed steel construction for toughness across a broad range of workpiece materials
• Double-end design provides two usable cutting ends per tool
• 30-degree right-hand spiral flutes promote efficient chip flow and reduce cutting forces
• Centercutting geometry enables plunge milling and slot entry
• Bright uncoated finish suited for general-purpose steel and ferrous alloy milling
• Right-hand cutting direction compatible with standard mill spindle rotation

Compatibility

Designed as a general-purpose replacement or production end mill for use in standard collet chucks and end mill holders accepting a 3/16-inch shank diameter on manual or CNC milling machines.

Installation Notes

Installation and tool changes must be performed with the machine spindle fully stopped and locked out per applicable machine safety procedures. Seat the shank fully into the collet or holder and torque the retention nut to the tool holder manufacturer's specification. Verify runout with a dial indicator before cutting. Select feeds and speeds appropriate for the workpiece material and machine rigidity; consult published HSS end mill feed-and-speed references for steel and stainless applications.
