Meet the Wiseman Threading Tools Bottom Lead Metric HSS Tap Right Hand - M40x1.5, a precision internal-threading tool built for reliability in metalworking. Crafted from high-speed steel and ground for a consistent, tight pitch, this tap delivers clean, accurate threads with every cut when used with proper lubrication and tapping technique.

• Size and standard: Metric M40x1.5 with a right-hand thread, conforming to ISO 529 dimensions for compatibility with standard nuts, bolts, and metric fittings.
• Bottom lead design: Optimized to engage smoothly and maintain steady thread formation, helping you achieve a true full-depth thread in through-holes and similar applications.
• Material and finish: High-speed steel (HSS) with a ground finish and no coating, prioritizing efficient cutting heat management and solid rigidity during tapping.
• General-purpose performance: A versatile, all-around tapping tool suitable for common metals encountered in workshops—from mild steels to cast irons—when paired with appropriate cutting fluid.
• Practical usage: Use with a tap wrench, apply a quality cutting fluid, and maintain a steady, perpendicular entry to avoid cross-threading. Ideal for both DIY projects and professional fabrication where metric threads are standard.

This single, reliable tap is designed to deliver repeatable results across multiple projects, making it a dependable addition to any metalworking toolbox. Its precise M40x1.5 right-hand thread and bottom lead geometry provide a practical, efficient solution for fabricators who value consistency and durability in their threading tools.
