Introducing the Tanoi Metric Left Hand Tap with Uncoated Spiral Flute, designed for metric left-handed threading across a wide range of materials. This tap is ideal for professionals and serious DIYers who need reliable reverse-direction tapping with clean, accurate threads.

• Left-Hand Thread Design: Specifically engineered to cut left-handed metric threads in reverse, enabling secure installations and controlled disassembly when a left-hand fastener is required.
• Size and Thread Pitch: M16x2.0 metric specification delivers a 16 mm major diameter with a 2.0 mm thread pitch for compatibility with standard left-handed hardware.
• Spiral Flute: Uncoated spiral flute geometry promotes efficient chip evacuation and smoother cutting, even in deeper through-holes.
• HSS‑E Material: Made from high-speed steel with cobalt (HSS-E) for enhanced hardness and wear resistance during tapping of tougher alloys.
• Uncoated Finish: Plain surface provides predictable friction behavior and the option to apply your own coating or lubrication based on your machining setup.
• V3 Refinement: Version 3 construction reflects improved geometry and durability for consistent thread formation across varying materials.
• Wide Material Compatibility: Designed to work across a broad spectrum of metals, making it a versatile tool for metalworking projects and professional repair tasks.

This left-hand tap helps you create reliable left-handed threads or repair existing ones with confidence. The combination of M16x2.0 sizing, spiral flutes for chip control, and a robust HSS‑E core delivers durable performance in everyday workshop tasks—from automotive repairs to fabrication and prototyping—without the need for multiple specialist taps. Use with appropriate cutting fluid and secure workholding to achieve clean, accurate threads and extend tool life.
