Value Collection 720-1027 Square End Mill 21/64 in 2 Flute Hss

Product Description

The VALUE COLLECTION 720-1027 is a single-end, two-flute square end mill designed for general-purpose milling operations in metalworking environments. It is manufactured from M2 high speed steel with a bright/uncoated finish and features a 30-degree helix angle with right-hand cut and right-hand flute direction. The cutter measures 21/64 inches (0.3281 inches) in diameter with a 9/16-inch (0.5625 inches) length of cut, making it well suited for slotting, profiling, and light peripheral milling. This tool is centercutting, allowing plunge entry into the workpiece. Machinists and tool-and-die professionals in job shops and production environments are the primary users.

The 720-1027 is applied across a range of primary workpiece materials including steel, stainless steel, cast iron, and aluminum and non-ferrous metals. Its regular-length geometry and fractional-inch sizing fit standard collet and end mill holder setups found in vertical milling machines, CNC machining centers, and knee mills. The 3/8-inch shank diameter is a common fractional size that accommodates most standard collets and tool holders without adapters.

Key Features

• M2 high speed steel construction for wear resistance across ferrous and non-ferrous materials
• 21/64-inch (0.3281 inches) cutting diameter with 9/16-inch length of cut
• 30-degree helix angle promotes smooth chip evacuation and reduced cutting forces
• Centercutting design allows direct plunge milling without pre-drilling
• Bright/uncoated finish compatible with standard cutting fluid applications
• Right-hand cut, right-hand spiral, single-end configuration for conventional milling setups

Compatibility

Designed as an OEM-style replacement or standard tooling selection for any milling setup requiring a 3/8-inch shank, 21/64-inch diameter, two-flute square end mill in fractional-inch sizing.

Installation Notes

This end mill is installed by a machinist or tooling technician. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the 3/8-inch shank fully into the collet or end mill holder and torque the retention mechanism per the holder manufacturer's specification. Verify runout with a dial indicator before beginning the cut, and apply appropriate cutting fluid for the workpiece material being machined.
