Dormer E651 UNC Spiral Flute Tap & Drill Set

The No 10 UNC spiral flute tap and drill set provides precise threading for smaller-scale engineering and fabrication work. Creating a 3.9mm thread diameter with 15mm threading length, this compact combination tool handles number ten UNC threads efficiently in applications such as electronics enclosures, instrumentation panels and light metalwork. The single-operation design is particularly valuable when multiple small threaded holes are required, saving considerable time compared to traditional methods.

Engineered from high-speed steel with steam tempering, this lightweight tool maintains sharp cutting edges throughout its working life. The 5mm connection diameter suits smaller power drill chucks, whilst the two-flute spiral design ensures effective chip evacuation even at this compact scale. Whether you're a professional working on precision equipment or a DIY enthusiast tackling detailed projects, this tool eliminates the fiddly process of changing from drill bits to small taps.

Features and Benefits:
• Combined drill-and-tap completes threads in one efficient pass
• Steam-tempered coating retains lubricant for smoother operation
• Compact design ideal for smaller-diameter precision work
• Spiral flute configuration provides reliable swarf removal
• Direct power tool compatibility removes need for tap wrenches
• Right-hand cutting for standard threading applications
