Engineered for G (BSP) threaded connections in through-hole work, the OSG G-BSP A-Spiral Point Tap delivers precise, reliable threading with durable performance. Designed for machinists and shops that demand consistency in high-speed operations, it excels in pipe and fitting applications where BSP threads are standard.

• Thread Type: G (BSP) thread profile for accurate, industry-standard BSP threading in through-hole work.
• A-Spiral Point: Optimizes chip evacuation by pushing chips ahead of the tap, reducing binding and improving hole cleanliness.
• Material: Powder metal substrate for enhanced wear resistance, durability, and heat tolerance during demanding tapping cycles.
• Coating: TiCN coating lowers friction, extends tool life, and sustains cutting efficiency across materials.
• Direction: Right-hand threading designed for conventional turning and tapping operations.
• Size: 1/4 x 19, offering a compact, common BSP size suitable for a range of connectors and fittings.
• Through-Hole Compatibility: Specifically formulated for through-hole DIN5156 applications to ensure reliable thread formation in through-holes.

This tapping solution provides tangible value in real-world production: the TiCN-coated, powder-metal body resists wear and heat buildup during high-speed tapping, while the spiral-point geometry speeds up chip clearance and minimizes tool seating pressure. The result is cleaner threads, reduced cycle times, and longer tool life, helping you meet tight tolerances in a variety of materials and thicknesses. Ideal for plumbing, pneumatic, and hydraulic components, as well as general machine shop work that requires durable, precise G (BSP) threads in through-holes.
