Wiseman Threading Tools Second Lead Metric HSS Tap Right Hand - M11x1

Meet the Wiseman M11x1 Second Lead Metric HSS Tap — a precision threading tool built for reliable, rapid metric hole tapping. Ground to a precise finish and uncoated for straightforward cutting, this high speed steel tap delivers consistent threads in a wide range of general purpose applications. With ISO 529 compliant dimensions and a right-hand thread, it’s the go-to choice for metric through-holes that demand accuracy and durability.

The second lead design, also known as a two-start tap, engages more thread starts along the body. That means faster cutting and better chip evacuation without sacrificing thread quality. For longer thread runs or tougher materials, this two-start profile can significantly improve tapping efficiency while maintaining clean, consistent engagements.

Key features and specifications

• Size and pitch: M11x1 metric thread (11 mm major diameter, 1.0 mm pitch)
• Thread direction: Right-hand, suitable for standard metric assemblies
• Lead: Second lead (two-start) design for quicker cutting and smoother entry
• Material: High speed steel (HSS) for durability and sharp cutting edges
• Finish: Ground, uncoated tool for predictable cutting behavior and easy lubrication
• Compliance: ISO 529 thread standards ensure compatibility with common metric components

What makes this Wiseman tap a standout choice

For machinists and DIY affinity enthusiasts working with metric hardware, this tap answers the need for dependable threading across a variety of materials, including steel, cast iron, and certain aluminums. The two-start design reduces threading time and improves reliability on through-holes, while the uncoated HSS construction accepts standard cutting fluids and coolants to keep the tip sharp and the chips moving.

Ideal use cases

• Tapping metric through-holes in machine frames, brackets, and automotive components that use M11x1 threads
• Prototyping and repair work where quick, repeatable threads are essential
• Maintenance projects in which consistent thread accuracy is critical for fasteners and inserts

Practical tips for best results

• Lubricate with a suitable cutting fluid to extend the tap’s life and improve finish quality
• Align the tap carefully with the hole to prevent cross-threading and tap breakage
• Back off periodically to break chips and prevent binding, especially with tougher materials
• Use steady, even pressure and avoid forcing the tap through the workpiece

Choose the Wiseman M11x1 Second Lead Metric HSS Tap when you need precise, efficient metric threading with dependable performance across a range of standard machining tasks. It’s engineered to deliver clean threads, repeatable results, and long-term reliability in everyday metalworking projects.
