Wiseman Threading Tools Bottom Lead Metric HSS Tap Right Hand - M45x2 is a precision-engineered tapping solution designed for heavy-duty metalworking. Crafted from high-speed steel and ground for accuracy, this right-hand threaded tap follows ISO 529 dimensions for dependable, repeatable results across a range of projects.

The uncoated HSS construction ensures fast cutting and long tool life when used with proper cutting fluids. With a bottom lead design, this bottoming tap can reach near the end of the hole to produce full-depth M45x2 threads, making it ideal for blind holes and through-holes that demand maximum engagement.

Key specifications

• Size and thread: M45 x 2 metric thread, right-hand orientation
• Lead type: Bottom lead (bottoming) for deep, full-depth threads
• Material: High Speed Steel (HSS), ground for precision
• Coating: Uncoated for compatibility with a wide range of cutting fluids
• Standard: ISO 529 dimensions for metric threads

Practical applications

Ready for tough metalworking tasks, this Wiseman tap is suitable for machining steel, cast iron, and other common engineering metals. Use it in:

• Fabrication and repair projects where large-diameter metric threads are required
• Automotive components, machinery housings, and structural parts needing robust fasteners
• Blind-hole tapping where full thread depth to the bottom of the hole is essential

How to get the best results

Maximize performance with these guidelines:

• Always use an appropriate cutting fluid or oil to reduce heat and chip buildup.
• Align the tap carefully with the hole to prevent cross-threading; start with light, steady turns and progress gradually.
• Maintain steady downward pressure and use a tap wrench or drill press with a tapping setup to control torque.
• Clear chips frequently and back off slightly to break them before continuing deeper.
• After tapping, remove the tap with a gentle reverse turn to avoid binding.
