The OSG BSW Spiral Point Threading Tap is built for professionals who need fast, reliable through-hole threading. Crafted from HSS-E with a steam oxide finish, this tap delivers precise threads and long tool life in demanding machining environments.

• Thread Form: BSW spiral point geometry designed to push chips forward and maintain efficient cutting in through-hole applications.
• Material: HSS-E (high-speed steel with cobalt) for enhanced hardness and heat resistance during tough tapping jobs.
• Coating: Steam oxide coating to reduce wear, improve heat tolerance, and extend tool life in challenging materials.
• Through-Hole Design: Optimized for through-hole tapping with clear chip evacuation and consistent thread quality.
• Size: 3/4 x 10 (BSW, 3/4 in major diameter with 10 TPI) for standard through-hole threads.
• Brand Engineering: From OSG, a recognized leader in precision threading technology and durable tooling.

With this tap, you’ll achieve precise, repeatable threads that fit securely in assemblies. The spiral point design promotes efficient chip evacuation, reducing the risk of clogging and tool deflection. The cobalt-enhanced HSS and steam oxide coating work together to deliver improved wear resistance and longer tool life, boosting productivity in through-hole tapping tasks across common metals. Ideal for shop-floor production, maintenance, and fabrication projects where consistent, high-quality threads are essential.
