The OSG RC BSPT A-Spiral Flute Threading Tap is built for precision BSPT threads in blind holes, making it a reliable choice for professional machinists and fabrication shops. Its spiral flute design and rugged powder-metal body deliver dependable performance in demanding materials.

• Thread type: British Standard Pipe Taper (BSPT) threads for blind-hole tapping, DIN5156 compliant
• A-Spiral flute: Optimized for efficient chip evacuation in through-hole and blind-hole tapping
• Material: Powder metal construction delivers exceptional wear resistance, durability, and toughness
• Coating: TiCN coating enhances heat resistance and reduces friction for longer tool life
• Hand: Right-hand threading for standard tapping operations
• Size: 1/16" diameter x 28 TPI (1/16 x 28 BSPT), DIN5156 specification
• Applications: Ideal for blind-hole threading in challenging materials and high-performance assemblies

With this tap, you’ll achieve clean starts, precise engagement, and consistent thread quality. The TiCN coating minimizes heat buildup and friction, allowing for faster cutting and reduced wear, while the powder-metal substrate stands up to repeated use in tight blind holes. The spiral flute design helps prevent chip congestion, keeping feeds steady and reducing the risk of binding in confined spaces. This tap is well suited for plumbing interfaces, hydraulic and pneumatic components, and other assemblies requiring reliable BSPT connections in limited-access environments.
