The OSG RC BSPT A-Spiral Flute Threading Tap is a high-performance tool designed for tapping British Standard Pipe Taper threads in blind holes, delivering precise results with durable, long-lasting performance.
- Tap Type: RC (BSPT) with an A-Spiral flute geometry engineered for efficient chip evacuation in blind-hole tapping.
- Material: Powder metal construction offering exceptional wear resistance, toughness, and durability in demanding materials.
- Coating: TiCN coating to reduce friction, improve heat resistance, and extend tool life for faster cutting and fewer tool changes.
- Thread Direction: Right-hand threading, suitable for standard BSPT applications.
- Application: Specifically designed for cutting BSPT threads in blind holes, compliant with DIN5156 threading standards.
- Size: 1/8" diameter with 28 TPI for precise BSPT thread formation in tight or restricted spaces.
This tap combines a spiral flute design with a robust powder-metal substrate and TiCN coating to deliver reliable, repeatable threading in challenging materials. Its Chilean-friendly geometry helps maximize chip evacuation, reducing the risk of chip packing and tap breakage in blind-hole applications. Ideal for CNC or manual machining environments where accurate BSPT threads and extended tool life are priorities.
