The OSG Metric Spiral Point Threading Tap is a precision tapping tool built for through-hole work in metal components. Designed for machinists and hobbyists who demand reliable thread quality, it delivers smooth cutting and extended tool life.

• Tool Type: Metric spiral-point threading tap optimized for through-hole applications
• Material: HSS‑E (high-speed steel with cobalt) for superior wear resistance and heat tolerance
• Coating: Steam oxide coating to enhance durability and reduce wear
• Thread Size: M1.6 x 0.35 (metric threading standard)
• Chip Evacuation: Spiral-point geometry facilitates forward chip evacuation for cleaner cuts
• Application: Ideal for precision through-hole tapping in small-diameter parts and assemblies

This tap is engineered to maintain accuracy under demanding conditions, helping you achieve consistent thread quality with fewer tool changes. The cobalt-enhanced HSS and steam-oxide finish work together to resist heat and wear, delivering dependable performance across multiple holes and parts. The spiral-point design speeds operations by pushing chips ahead of the cutting zone, reducing clogging and improving surface finish on through-hole threads. Whether you’re producing precision housings, small fasteners, or intricate fixtures, this OSG tap offers reliable performance, repeatability, and extended service life.
