Dormer Light E651 Unc Spiral Flute Tap & Drill Set

DORMER

The No 8 UNC spiral flute tap and drill set provides versatile threading capability for smaller-scale engineering applications. Producing a 3.5mm thread diameter with 12mm threading length, this compact combination tool is perfect for electrical components, control equipment, light assemblies and general small metalwork where number eight UNC threads are required. The integrated drill-and-tap design streamlines workflow significantly, particularly valuable when working with multiple threaded fixings. Engineered from high-speed steel with a steam-tempered coating, this tool delivers reliable cutting performance across repeated use. The 4.5mm connection diameter provides secure chuck engagement, whilst the two-flute spiral geometry evacuates metal chips effectively throughout the threading operation. Whether you're a professional tradesperson or a home workshop user tackling smaller projects, this tool eliminates the need to change between drilling and tapping equipment for these commonly-used threads.
