Precision threading tap designed for through-hole BSF applications. Built from HSS‑E (high-speed steel with cobalt) and finished with a durable steam oxide coating, it delivers reliable, long-lasting performance in demanding machining tasks.

• Material: HSS‑E (high-speed steel with cobalt) for outstanding hardness and heat resistance.
• Coating: Steam oxide finish reduces wear and improves lubricity for longer tool life.
• Design: BSF Spiral Point geometry optimizes chip evacuation in through holes for cleaner threads.
• Application: Specifically designed for through-hole tapping, ensuring consistent thread formation.
• Size: 1 x 10 (as listed in the product title).

The tap’s spiral point pushes chips ahead as you cut, minimizing chip packing and reducing cycle times. The robust HSS‑E composition, combined with the steam oxide coating, offers improved heat tolerance and extended life in a wide range of machinable materials when used with proper lubrication. This makes it well suited for production runs, part repair, and any project requiring dependable BSF threads in through-hole applications.
