OSG Threading Tap - BSW Spiral Point HSS-E - Steam Oxide Coated - Through Hole - 1.1/8 x 7

The OSG BSW Spiral Point Threading Tap is a precision tool built for professionals who need fast, clean through-hole threading with long tool life. It delivers reliable, accurate BSW threads in demanding metalworking applications.

• Thread Type: BSW spiral point threading tap designed for through-hole tapping, promoting efficient chip evacuation and smooth thread formation.
• Material: HSS-E (high-speed steel with cobalt) for superior hardness, heat resistance, and edge retention under heavy cutting.
• Coating: Steam oxide coating enhances wear resistance and reduces friction during cutting for longer tool life.
• Chip Evacuation: Spiral point geometry funnels chips forward, minimizing clogging in through-hole work and improving cycle times.
• Size & Reach: Through-hole design with 1-1/8 in diameter and 7 in overall length, suitable for deeper holes and extended reach.
• Precision & Finish: Engineered to produce clean, consistent threads with reliable pitch accuracy across multiple passes.

This tap is ideal for metalworking tasks that require durable, repeatable BSW threading in through-holes—from repair and fabrication to automated production environments. The combination of cobalt-enhanced HSS, a steam oxide coating, and spiral point geometry translates to better heat resistance, longer tool life, and fewer interruptions due to chip buildup. For best results, pair with appropriate cutting fluid and employ steady feeds and controlled speeds to maximize thread quality and tool longevity.
