Introducing the Wiseman Threading Tools Bottom Lead Metric HSS Tap Left Hand – M18x2. This high-speed steel ground tap is built for precision, durability, and reliable performance when you need clean, accurate internal threads with a left-hand configuration. Uncoated by design, it invites your preferred cutting fluids and lubricants to optimize chip formation and tool life, delivering consistent results batch after batch.

• Left-hand thread, M18x2: ideal for applications where the fastener should tighten in reverse, providing secure, anti-loosening performance in equipment and assemblies that require a reverse-threaded fit.
• Bottom lead design: engineered to start and progress threads smoothly into deeper holes, reducing misalignment and improving finish on longer engagements.
• ISO 529 compliant dimensions: ensures compatibility with standard metric nuts and threaded holes across global manufacturers, simplifying replacements and repairs.
• High-speed steel (HSS) ground finish: delivers tight pitch accuracy and dependable cutting action, with an uncoated surface that accommodates your preferred lubrication strategy.
• General-purpose, durable tool: a versatile tapping solution for automotive, industrial maintenance, machinery builds, and heavy-duty metalworking projects requiring precise left-handed threads.

Use case scenarios include repairing or fabricating components with reverse-threaded fasteners, creating left-hand threaded jacks, fittings, or adaptors, and performing maintenance on machinery where a left-hand thread is specified. Pair this tap with a compatible tap wrench or a machine-driven tapping setup, apply appropriate cutting fluid, and follow steady, graduated passes to achieve clean, compliant threads without chatter.

Ideal for professional machinists, workshop technicians, and serious DIY enthusiasts who demand reliable performance from a single, purpose-built tapping tool for metric M18x2 left-hand threads.
