The OSG Threading Tap is a high-performance tool designed for cutting British Standard Whitworth (BSW) threads in blind holes. Built for professional machinists and workshops, it combines durability with precise, clean thread results in recessed interiors.

• Thread Type: British Standard Whitworth (BSW) threading, DIN2184-1 specification for blind-hole tapping
• Flute Design: A-Spiral flute enhances chip evacuation in blind holes, reducing the risk of snag and giving smoother finishes
• Material: Powder metal construction delivers improved wear resistance and long tool life
• Coating: TiCN (Titanium Carbonitride) coating lowers friction and increases hardness for higher cutting speeds and temperatures
• Hand: Right-hand thread for standard internal threading applications
• Hole Type: Optimized for blind holes where chip removal and control are critical
• Size: 5/8 x 11 tapping size, a common dimension for robust BSW applications

Designed to tackle challenging blind-hole tapping with reliability, this TiCN-coated powder-metal tap helps you achieve precise thread engagement, better surface finish, and longer tool life. The combination of A-Spiral flutes, durable substrate, and advanced coating makes it suitable for repetitive production runs or precision repairs in automotive, machinery, and general engineering contexts.
