Dormer E651 UNC Spiral Flute Tap & Drill Set

The No 12 UNC spiral flute tap and drill set offers reliable threading for smaller engineering applications requiring this number gauge thread. Producing a 4.5mm thread diameter with 15mm threading length, this compact combination tool is ideal for electrical equipment, control panels, light fixtures and precision metalwork where number twelve UNC threads are specified. The integrated drill-and-tap design saves valuable time, particularly when working with multiple threaded holes.

Manufactured from high-speed steel with a steam-tempered finish, this tool delivers consistent cutting performance throughout its service life. The 5.6mm connection diameter provides secure engagement in standard drill chucks, whilst the two-flute spiral pattern evacuates metal chips effectively. Both professional electricians and DIY enthusiasts will appreciate the convenience of creating accurate small threads without the need to switch between drilling and tapping equipment.

Features and Benefits:
• Single-pass operation dramatically reduces threading time
• Steam-tempered surface holds cutting fluid for improved finish
• Two-flute spiral design ensures effective chip removal
• Cylindrical shank with square drive fits power tools
• Right-hand cutting direction for conventional applications
