Dormer E651 UNC Spiral Flute Tap & Drill Set

The No 6 UNC spiral flute tap and drill set is the smallest capacity in this range, designed for delicate threading work requiring precision. Creating a 2.85mm thread diameter with 12mm threading length, this compact combination tool excels in electronics assembly, small instrumentation, model engineering and detailed metalwork where number six UNC threads are needed. The single-operation design is especially beneficial for fine work, eliminating the risk of misalignment when switching between drill bits and small taps.

Crafted from high-speed steel with steam tempering, this diminutive tool maintains its cutting edge despite its small size. The 3.5mm connection diameter suits precision drill chucks, whilst the two-flute spiral configuration ensures chips are evacuated efficiently even in these fine threads. Professional electronics technicians and precision engineering enthusiasts will value the accuracy and convenience of creating small threads without changing tools mid-operation.

Features and Benefits:
• Combined drilling and tapping maximises efficiency on fine threads
• Steam-tempered coating retains lubricant for controlled cutting
• Compact scale ideal for precision and detailed metalwork
• Spiral flute design provides chip evacuation at small diameters
• Power tool compatible for consistent operation
• Right-hand cutting for standard threading work
