Value Collection 27664 Square End Mill 1in 2 Flute Hss

Product Description

The VALUE COLLECTION 27664 is a single-end square end mill designed for milling flat surfaces, slots, and profiles in a wide range of materials. Built from M2 high speed steel with a bright/uncoated finish, it offers solid performance in general-purpose machining applications. The tool features a 1 inch cutting diameter, a 1-5/8 inch length of cut, and a 30-degree helix angle that promotes efficient chip evacuation. With two flutes and a right-hand cutting direction, it is suited for conventional milling operations on manual mills and CNC machining centers. Machinists and tool-and-die professionals are the primary users of this type of end mill.

This end mill is appropriate for use in job shops, maintenance machining, and production environments where a general-purpose HSS tool is preferred over carbide. The 1 inch shank diameter matches the cutting diameter, making it compatible with standard ER and straight-shank collet systems. It is center-cutting, allowing plunge entry into workpieces. Typical materials machined with M2 HSS end mills include mild steel, aluminum, brass, plastics, and similar machinable materials at moderate cutting speeds.

Key Features

• M2 high speed steel construction for general-purpose durability across a range of machinable materials
• Center-cutting geometry allows direct plunge milling without a pre-drilled entry hole
• 30-degree right-hand spiral flutes promote chip evacuation and reduce heat buildup
• Bright/uncoated finish suitable for use with or without cutting fluid
• Two-flute design provides larger chip clearance, well-suited for softer materials and slotting operations
• Single-end configuration with consistent 1 inch shank and cutting diameter for straightforward tool holding

Compatibility

Designed as a general-purpose replacement or stock end mill for use in standard milling machines and CNC machining centers accepting a 1 inch straight shank.

Installation Notes

Installation is performed by qualified machinists. Secure the shank fully within the collet or end mill holder to the recommended engagement depth before tightening. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Follow applicable machine tool safety procedures and shop standards when setting speeds and feeds for the specific workpiece material.
