Wiseman Threading Tools Second Lead Metric HSS Tap Right Hand - M50x2 is a high-speed steel ground tap built for dependable general-purpose metric threading. Uncoated and engineered to ISO 529 dimensions, this tap delivers consistent, clean threads with every cut, making it a reliable choice for everyday metalworking tasks.

Designed for efficiency and precision, this tap features a second lead (double-lead) geometry and a right-hand thread. The second lead design increases the linear advancement per rotation, speeding up tapping in through-holes while maintaining chip clearance and thread accuracy. For shop projects, prototyping, or maintenance work, it translates into fewer passes and smoother operation without sacrificing thread integrity.

Key specifications and benefits at a glance:

• Material and finish: High-speed steel (HSS) with a ground finish for accurate alignment, resilient cutting, and dependable wear resistance. Uncoated to avoid compatibility issues with certain materials and lubricants.
• Thread geometry: Right-hand thread with a second lead design for faster tapping and improved chip evacuation in through-holes.
• Standards: ISO 529 compliant dimensions ensure compatibility with standard metric threads and mating nuts or bolts.
• Size: Metric M50x2, suitable for larger metric threads where stability and strength are critical.
• General-purpose use: Adaptable to a variety of common metals, including steel, aluminum, and brass, provided you maintain proper cutting fluid and lubrication.

Practical usage tips to get the most from your tap:

• Pre-drill to the recommended tapping drill size for M50x2 to ensure clean entry and reduce breakout.
• Apply a suitable cutting fluid or oil to minimize heat and extend tool life.
• Keep the tap square to the workpiece and apply steady, even pressure. Back off periodically to break and clear chips if needed.
• Use a proper tap wrench or machine tap setup to maintain consistent torque and prevent bending or breakage.
• Finish by removing the tap with a gentle, even turn, then inspect the new threads for smooth engagement.
• Store in a protective case or rack to preserve the precision of the threads for future use.
