Cut true, precise internal threads with confidence using the Wiseman Threading Tools Bottom Lead Metric HSS Tap in M11x1. Built for metalwork where depth matters, this bottoming tap combines rugged HSS performance with carefully engineered geometry to deliver reliable threads every time.

• Bottom lead design supports full-thread engagement from the outset, making it ideal for blind holes and deep-threading tasks where you need the thread to reach the bottom of the hole.
• Metric M11x1 with ISO 529 alignment ensures clean, accurate threads that mate predictably with standard fasteners and components used in modern assemblies.
• Right-hand thread aligns with the most common threading direction in machinery and DIY projects, providing straightforward operation and consistent results.
• High-speed steel, ground finish delivers precise flank geometry and dependable cutting performance, even under repeated use in metalworking environments.
• Uncoated, general-purpose tap designed for broad material compatibility without coating buildup, making it a versatile choice for steel, cast iron, and many alloys when paired with proper cutting fluid.
• ISO 529 dimensional accuracy guarantees repeatability across tools and components, so you can trust each tap to produce the same thread pitch and depth.

Practical use cases and tips

Ideal for automotive repairs, fixture fabrication, and general metalworking where precise internal threads are required. Use with a stable tapping setup and appropriate cutting fluid to minimize heat and extend tool life. Start with a clean, aligned hole, apply steady pressure, and back off to clear chips as you approach full thread depth. Finish with a light pass and inspect the threads with a gauge to confirm proper engagement and tolerance.

This Wiseman bottom-leading HSS tap is a dependable addition to professional machinist kits, workshop benches, and DIY setups alike. It’s purpose-built to deliver consistent, accurate M11x1 threads, helping you assemble components with confidence and reduce the need for re-tapping.
