This micro cutting tool is sized for precision work and tight spaces. All dimensions are approximate. Shank diameter: approximately 3.175 mm Cutting edge diameter: approximately 3.175 mm Cutting edge length: approximately 17 mm Total length: approximately 40 mm Why it helps you Consistent engagement: the same diameter on shank and edge promotes stable cuts and predictable finish. Reach where it matters: 17 mm cutting edge lets you access deeper pockets without sacrificing rigidity. Compact, versatile form: 40 mm total length is ideal for small CNC routers and micromilling machines. Compatibility Designed for standard 1/8 inch (3.175 mm) tool holders and collets found on most CNC and micromilling setups. Use scenarios Engraving fine details on wood, plastic, or soft metals with clean edges. Precision pocketing or smallslot finishing in aluminum prototypes or PCBrelated work. Deburring and cleanup in tight corners where a rigid, smalldiameter tool is required. Material note The material is not specified in these specs; confirm with the supplier for compatibility with carbide or speed steel tools in your setup.
