The OSG BSP Spiral Point Threading Tap is a high-performance tool designed to cut BSP threads in through-holes with precision and durability. Built for professional machinists, shops, and maintenance teams, it delivers clean, accurate threads and extended tool life through advanced materials and geometry.

• Material: HSS‑E (high-speed steel with cobalt) for enhanced wear resistance and heat tolerance during tapping.
• Coating: Steam oxide coating to reduce friction, improve lubrication retention, and resist corrosion.
• Threading Design: Spiral point geometry that efficiently evacuates chips and supports through-hole accuracy.
• Thread Type: BSP (British Standard Pipe) threading to meet standard pipe-fitting specifications.
• Size & Pitch: 3/4 x 14 BSP through-hole tap for robust, dependable threading in metal components.
• Through-Hole Capability: Optimized for through-hole applications, delivering consistent full-depth threads with less runout.
• Brand Promise: OSG’s engineering ensures precise thread form, tight tolerances, and longer tool life in demanding machining tasks.

With the OSG BSP Spiral Point Threading Tap, you gain reliable performance in metal fittings, manifolds, and components requiring BSP threads. The cobalt-enhanced steel and steam oxide coating work together to withstand high cutting temperatures, minimize wear, and extend intervals between tool changes. The spiral point design accelerates chip evacuation and reduces the risk of chip packing, helping you maintain steady feeds and finishes even on longer through-hole tap jobs. This tap is ideal for professional shops tackling plumbing, hydraulic, and pneumatic fittings where precise, durable BSP threads are critical for leak-free connections and consistent assembly quality.
