OSG Threading Tap - BA Spiral Flute HSS-E - Steam Oxide Coated - Blind Hole - 0BA

The OSG BA Spiral Flute Threading Tap is a precision tool built for blind-hole threading in metalworking environments. Designed for machinists and fabricators who demand consistent, high-quality internal threads, it combines durability with efficient chip control to tackle demanding applications.

• Thread size: 0BA — BA-series internal thread size for compact assemblies.
• Material: HSS‑E cobalt (high‑speed steel with cobalt) for superior wear resistance and heat tolerance.
• Coating: Steam oxide finish to reduce friction, improve lubricity, and extend tool life.
• Flute design: BA spiral flute engineered to promote efficient chip evacuation in blind-hole workpieces.
• Application: Optimized for precise internal threads in blind holes, helping you access tight spaces with reliable results.
• Quality and compatibility: Engineered for consistent thread forms and long service life when used with standard tapping practices and appropriate lubrication.

With the OSG BA Spiral Flute Threading Tap, you get reliable performance where it matters most—clean, accurate threads in hard‑to‑reach blind holes. The cobalt-enhanced HSS material stands up to higher cutting temperatures, while the steam oxide coating reduces wear and helps maximize tool life. The spiral flute design ensures chips are evacuated efficiently, lowering the risk of chip binding and tap breakage during deep or narrow holes. This tap is a dependable choice for workshops and production environments that require repeatable, high‑quality threads in critical components.
