Value Collection 27648 Square End Mill 9/16 in 2 Flute Hss

Product Description

The VALUE COLLECTION 27648 is a single-end square end mill designed for general-purpose milling operations in metal fabrication and machining environments. It measures 9/16 inches in diameter with a 1-1/8 inch length of cut and a 3-1/8 inch overall length. The cutting tool is manufactured from M2 high speed steel with a bright/uncoated finish, making it well suited for milling mild steels, aluminum, and non-ferrous materials at moderate cutting speeds. With a 2-flute configuration and a 30-degree right-hand helix, it balances chip evacuation and cutting efficiency in standard slotting and peripheral milling applications. Licensed machinists and CNC operators are the typical end users.

This end mill fits standard milling setups in job shops, maintenance machining, and production environments where a reliable HSS tool is preferred over carbide. The 1/2 inch shank diameter is compatible with common ER collet systems and end mill holders. Centercutting geometry allows plunge milling as well as side and face milling. It is appropriate for use in manual knee mills and CNC machining centers running conventional or climb milling passes on ferrous and non-ferrous workpieces.

Key Features

• M2 high speed steel construction provides toughness and re-sharpenability for general-purpose milling
• 2-flute spiral design promotes chip evacuation during slotting and plunge cuts
• 30-degree right-hand helix reduces cutting forces on workpiece and machine spindle
• Centercutting geometry enables direct plunge entry without a pre-drilled hole
• Bright/uncoated finish suitable for use with standard cutting fluids and coolants
• Single-end design with 1/2 inch shank for compatibility with standard collet and holder systems

Compatibility

Designed as a standard replacement or working tool for milling setups requiring a 9/16 inch diameter, 2-flute square end mill with a 1/2 inch shank in ER collet chucks, end mill holders, or side-lock holders accepting that shank size.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Secure the shank to the recommended insertion depth in the collet or holder before torquing to the tool holder specification. Ensure the spindle is fully stopped and locked out before changing tooling. Verify runout with a dial indicator after installation to confirm concentricity before engaging the cut.
