Value Collection 720-1666 Square End Mill 11/64 in 2 Flute Hss

Product Description

The VALUE COLLECTION 720-1666 is a double-end, two-flute square end mill designed for material removal and profiling in steel, stainless steel, cast iron, and high-temperature alloys. Manufactured from M2 high speed steel with a bright/uncoated finish, it offers a 0.1719-inch cutting diameter and a 0.875-inch length of cut. The 30-degree right-hand helix promotes efficient chip evacuation and reduces chatter during milling operations. Center cutting capability allows plunge entry as well as peripheral cutting. This tool is suited for manual mills, CNC knee mills, and light machining centers used in job shop and maintenance environments.

This end mill is appropriate for general-purpose milling operations including slotting, profiling, and step milling in ferrous and high-temp alloy workpieces. The double-end design provides two usable cutting ends, extending tool life between sharpening cycles. The long-length configuration gives added reach for deeper pocket work where standard-length tools fall short. Machinists and tool-and-die professionals working in production or prototype environments will find this a practical choice for small-diameter work.

Key Features

• Double-end design provides two cutting ends from a single tool
• M2 high speed steel construction handles steel, stainless steel, cast iron, and high-temp alloys
• 30-degree right-hand spiral helix promotes efficient chip flow and reduces cutting forces
• Center cutting geometry supports plunge milling entries
• Bright/uncoated finish maintains sharpness on general-purpose ferrous materials
• Long-length series (VCCCDE-HSS-2-30H) offers extended reach over standard-length tools

Compatibility

Designed for use in milling machines accepting a 3/16-inch shank diameter. Compatible with primary workpiece materials including steel (P), stainless steel (M), cast iron (K), and high-temperature alloys (S) per ISO material group designations.

Installation Notes

Installation is performed by machinists using a collet chuck or end mill holder rated for the 3/16-inch shank diameter. Ensure the machine spindle is fully stopped and the tool is secured to the appropriate depth before engaging the workpiece. Verify runout with a dial indicator after mounting to confirm concentricity. Follow shop-standard speeds and feeds for the workpiece material and tool diameter to avoid premature edge wear.
