Learn more about Klarna
Description
The OSG BSF Spiral Point Threading Tap is a precision tool designed for through-hole BSF threading work. It combines HSS-E cobalt performance with a durable steam oxide finish to deliver reliable, long-lasting results in demanding machining tasks.
- Thread Type: BSF (British Standard Fine) spiral-point geometry for efficient, through-hole tapping and clean thread formation.
- Material & Coating: HSS-E (high-speed steel with cobalt) with a Steam Oxide coating for enhanced heat resistance and wear protection.
- Size: 3/4" major diameter, 12 TPI (3/4 x 12 BSF) designed for through-hole applications.
- Chip Evacuation: Spiral-point design directs chips out of the hole, reducing rubbing and improving cutting action.
- Application: Specifically optimized for through-hole BSF threading tasks in metalworking and fabrication contexts.
With the OSG BSF Spiral Point Threading Tap, you’ll achieve precise, consistent BSF threads with extended tool life thanks to the cobalt-enhanced hardness and steam oxide coating. The spiral-point geometry minimizes chip buildup, enabling smoother starts and reducing the risk of tap binding in through-hole operations. This tap is well-suited for production runs or repair work in mechanical assemblies, automotive components, and industrial equipment where reliable BSF threads are essential.
