Wiseman Threading Tools Bottom Lead Metric HSS Tap Right Hand - M1.6x0.35

Introducing the Wiseman Threading Tools Bottom Lead Metric HSS Tap Right Hand - M1.6x0.35, a precision-ground tapping solution built for reliability in small-diameter threads. This high-speed steel tap is uncoated to provide consistent cutting action across a range of common metals, delivering clean, accurate threads with every pass. Designed to ISO 529 standards, it ensures compatibility and repeatable results in your workshop projects.

What makes this tap stand out

• Bottoming (bottom lead) design for full-thread depth in blind or recessed holes, so you can finish internal threads to the bottom of the workpiece without incomplete or inconsistent threads.
• Right-hand thread M1.6x0.35, ideal for standard orientation and common mechanical assemblies where standard threads are required.
• High Speed Steel (HSS), ground finish, uncoated for durability, sharpness, and efficient cutting in a wide range of metals. The lack of coating reduces friction build-up in delicate materials and enables smoother tooth engagement.
• ISO 529 compliant dimensions guarantee predictable, standardized results, so you can pair this tap with compatible drills and consistent tooling from your shop.
• General purpose tapping tool designed for precise, dependable threading in small-diameter holes, making it a versatile addition to any machinist’s or hobbyist’s toolkit.

Who and where you’ll use it

This tap is an excellent choice for precision work in small projects—from electronics housings and precision enclosures to miniature mechanical assemblies and repair work on compact components. It’s especially valuable when you need reliable full-depth threads in through-holes or blind holes where thread engagement must reach the last available coil. Ideal for hobbyists, makers, and professional hobby shops looking for a dependable metric tap that performs consistently across tasks.

How it helps you work smarter

• Reliable depth with bottom lead ensures complete threads, reducing the risk of loosened fasteners due to shallow threads.
• Consistent results thanks to ISO 529-compliant dimensions and a precise ground grind that delivers clean, square-cut threads with minimal burrs.
• Versatility suitable for a variety of general-purpose threading tasks in small components, letting you standardize on a single tap for multiple projects.

Practical tips for best results

• Pair this M1.6x0.35 bottoming tap with a sharp, properly sized drill bit (approximately 1.25 mm) to achieve optimal thread depth and alignment. Use a tapping fluid or light oil to reduce friction and extend tool life.
• Keep the workpiece securely clamped and ensure the tap remains perfectly perpendicular to the surface to prevent thread distortion.
• Work in stages: start with light cuts to establish a true thread, then progress gradually to full-depth cuts with steady, even pressure.
• After tapping, remove any chips with a gentle brush and inspect the thread run for uniform depth and cleanliness.
