OSG Threading Tap RC (BSPT) A-Straight Flute - Powder Metal Right Hand -TiCN Coated - Through and Blind Holes DIN5156 - 1/8 x 28

Engineered for precision BSPT thread cutting, the OSG RC threading tap with A-Straight flute is designed to deliver reliable, consistent BSPT threads in both through-hole and blind-hole applications. This right-hand tap combines durable construction with a finish that keeps cutting smooth under demanding conditions.

• Thread form: British Standard Pipe Taper (BSPT) threads built to DIN5156 specifications for dependable BSPT compatibility.
• Size and pitch: 1/8" nominal size with 28 threads per inch (1/8 x 28) for standard BSPT tapping tasks.
• Flute design: A-Straight flute geometry optimizes chip control and evacuation, especially in materials that produce long chips.
• Material: Powder metal body delivers enhanced wear resistance and durability for repeated use in tough environments.
• Coating: TiCN coating reduces friction and increases heat resistance, helping maintain steady cutting speeds and extend tool life.
• Working direction: Right-hand tapping for common BSPT installations and reliable thread formation.
• Hole compatibility: Suitable for both through-hole and blind-hole tapping, providing versatility across different workpieces.

This tapping solution focuses on delivering precise thread quality with durable performance. The combination of a powder-metal substrate and TiCN coating supports longer tool life, more consistent thread dimensions, and reduced rework, even in higher-temperature tapping scenarios. Ideal for manufacturing, maintenance, and repair of BSPT connections in hydraulic, pneumatic, and fluid-handling assemblies, it helps technicians achieve reliable, repeatable results with fewer interruptions.
