Value Collection 320-2066 End Mill Set 6 Piece Hss

Product Description

The VALUE COLLECTION 320-2066 is a 6-piece, single-end, 2-flute square end mill set made from M2 high speed steel with a bright uncoated finish. Designed for long-series milling applications, this set covers six common diameters ranging from 3/4 inch to 1-1/2 inches, making it a practical option for machinists who need multiple sizes on hand. The square end geometry is suited for general-purpose slot milling, profiling, and peripheral cutting in a range of materials. The set ships in a wood stand for organized storage and safe handling at the bench or in a tool crib.

This set is appropriate for use in manual mills, knee mills, and CNC machining centers where long-reach tooling is required. The 2-flute configuration provides good chip clearance in softer metals, plastics, and wood. The long-series length designation extends reach into deeper cavities or fixtures where standard-length end mills cannot access. Machinists, toolroom technicians, and job-shop operators working across varied workpiece materials will find the six-diameter assortment useful for reducing tool changeover between setups.

Key Features

• M2 high speed steel construction for durability across a range of cutting materials
• Bright uncoated finish — suitable for general-purpose milling without coating-specific limitations
• 2-flute design promotes chip evacuation in softer materials and slotting operations
• Long-series length provides extended reach for deep cavities and tall workpieces
• Single-end configuration — replace when worn without flipping
• Includes wood stand for organized, safe storage of all 6 pieces

Compatibility

Designed as a general-purpose replacement or starter set for use in standard milling machine spindles and CNC machining center tool holders accepting the shank diameters included in this set. Shank diameter is 3/4 inch across all pieces.

Installation Notes

End mills should be installed by a qualified machinist or toolroom technician using a properly sized collet or end mill holder rated for the shank diameter. Ensure the machine spindle is fully powered down and locked out before changing tooling. Inspect each end mill for runout after mounting and confirm tool holder torque meets the machine manufacturer's specification before beginning a cut. Follow applicable shop safety standards and machine tool operating procedures when handling and storing sharp cutting tools.
