Description
Precision threading with ease—introduce the Wiseman Threading Tools Bottom Lead Metric HSS Tap Left Hand – M9x1. This high-speed steel (HSS) tap is ground for accuracy, uncoated for versatile, general-purpose cutting, and built to deliver clean, repeatable left-hand threads in a variety of metals.
The tap is manufactured to ISO 529 dimensions and features a left-hand thread with a bottom lead design. The bottom lead helps the thread start and engage smoothly in restricted or blind holes, reducing chatter and promoting straighter, deeper threads with fewer passes.

Why this Wiseman tap stands out

How to use
- Prepare the hole: drill the recommended core hole according to ISO 529 for M9x1
- Lubricate: apply a light cutting oil to reduce heat and improve chip evacuation
- Align and start: keep the tap straight in the hole, then rotate counterclockwise to cut the left-hand thread
- Progress and clear chips: advance with steady pressure, pausing to clear chips to avoid over-tapping
- Verify: check the finished thread with a gauge to ensure correct depth and pitch
