- Size: 1/4 x 19
- Material: HSS-E (high-speed steel with cobalt) for enhanced toughness and heat resistance
- Coating: Steam Oxide finish that improves wear resistance and corrosion protection
- Flute Design: Spiral flute optimized for efficient chip evacuation, especially effective in blind-hole tapping
- Hole Type: Specifically suited for blind-hole machining to minimize bottoming issues and improve thread quality
- Brand/Technology: OSG advanced threading technology for high-precision, repeatable threads and longer tool life
This tap enables clean, accurate BSP threads in recessed or hard-to-reach holes, reducing the need for rework. The spiral flute helps carry chips out of blind holes, while the HSS-E core and steam-oxide coating deliver durability and heat tolerance for longer service life in busy production environments. Ideal for plumbing fittings, hydraulic components, and precision metalwork, it supports reliable performance, improved cycle times, and consistent thread quality.
