Meet the Wiseman Threading Tools Bottoming Metric HSS Tap Right Hand - M27x3. This precision tapping solution is engineered for durable, consistent threading in a range of metals, delivering reliable performance project after project. Crafted from high-speed steel and ground to exacting tolerances, it’s built to handle demanding machining jobs without sacrificing thread quality.

What makes this tap stand out:

• Bottoming (full-depth) lead designed to cut threads all the way to the bottom of the hole, ideal for through-holes and blind holes where maximum thread engagement is required.
• Metric size M27x3 with ISO 529 dimensions ensures compatibility with standard metric holes and taps, reducing guesswork on setup.
• Right-hand thread for conventional, clockwise cutting that suits most general metalworking projects.
• Uncoated HSS provides robust cutting performance and broad material compatibility, especially when used with appropriate cutting fluids for smooth chip formation.
• Ground geometry offers clean starts, improved alignment, and tighter, more consistent thread accuracy across runs.

This bottoming tap is ideal for engineers, machinists, hobbyists, and maintenance professionals who need dependable, repeatable threads in steel, cast iron, aluminum, and other metals. Pair it with a quality tap wrench, apply steady, even pressure, and use a suitable cutting fluid to maximize tool life and thread finish. Back off occasionally to clear chips, maintain control, and protect both tap and workpiece.
