Wiseman Threading Tools Hand Tap — Second Lead Tap with +0.005 tolerance for M4x0.7 is your go-to solution when every hole must accept a screw or fastener with precision-fit performance. This hand tap is engineered to deliver clean, accurate internal threads by hand, ensuring consistent thread form and tight engagement in every hole you tap.

• Accurate internal threading: +0.005 tolerance guarantees precise thread dimensions, reducing play and cross-thread risk for dependable fastener seating.
• Second lead design: The second-lead geometry lowers start-up torque and eases chip formation, delivering smoother tapping and better control in manual operations.
• Size and pitch: M4 x 0.7 taps are ideal for compact, lightweight assemblies where space is tight and thread quality matters.
• Durable construction: Built from durable materials to withstand repeated use in demanding environments, maintaining accuracy over time.
• Hand-tap versatility: Perfect for repair work, prototype builds, or on-site machining where a powered tap isn’t available.

This hand tap is designed for professionals and hobbyists who value precise thread quality and repeatable results. Use it to create clean internal threads in metal components, control-fit assemblies, or to repair stripped holes where exact thread geometry makes the difference between a reliable fastener and a loose, wobbly fit.

Practical tips for best results:

• Prepare the hole with a correctly sized pilot stop and clear through-hole to minimize chatter.
• Apply light oil or cutting fluid to the tap for cooler operation and smoother chip removal.
• Turn slowly, advancing a quarter-turn at a time, then back off slightly to break and clear chips before continuing.
• Clean the hole after tapping and inspect the thread for smooth engagement of the intended fastener.
