Description

Tanoi's Metric Left Hand Tap in M12x1.75 is a precision threading tool designed for metric internal threads with a left-handed cut. Built for professionals and serious hobbyists, it delivers reliable, controlled threading for reverse-thread applications and specialty projects.

  • Thread Direction: Left-hand cutting for internal metric threads, enabling reverse-thread fastening without rework.
  • Size & Pitch: M12 × 1.75 metric standard, suitable for a wide range of fasteners and components.
  • Material & Coating: HSS‑E construction (high-speed steel, enhanced) with no coating for robust, precise cutting across many materials.
  • Flute Design: Spiral flute geometry to improve chip evacuation and reduce binding during deeper cuts.
  • Construction Version: V3 precision engineering delivers consistent thread depth and finish across multiple uses.
  • Material Compatibility: Designed for a broad range of materials, from softer alloys to tougher steels, with appropriate lubrication.

Benefits: This left-handed tap enables you to efficiently create clean, accurate left-hand threads in a single, controlled operation. The spiral-flute design helps clear chips quickly, reducing heat and chatter, which translates to longer tool life and higher-quality threads. The uncoated HSS‑E body provides reliable performance across common machining materials, making it a versatile addition to any toolkit. Ideal for automotive work, maintenance, and precision assemblies where reverse-thread fasteners or left-hand threaded components are required. For optimal results, use appropriate cutting fluid, maintain a steady feed, and back off slightly at the end of each thread pass to ensure smooth, finished threads.
