Wiseman M39x2 Taper Lead HSS Tap, Right-Hand is a precision internal-threading tool designed for dependable, real-world metalworking outcomes. Crafted from high-speed steel and ground for accuracy, this tap covers general-purpose tapping needs with a focus on long-lasting performance and smooth, consistent cuts. The taper lead eases engagement, helping you start threads cleanly in harder materials or tight holes, while the right-hand thread orientation matches standard clockwise tapping applications. With ISO 529 dimensions, you get predictable fit and compatibility across commonly threaded components.

• Material and finish: High-speed steel, ground for precision; uncoated for versatile use with most cutting fluids and materials.
• Thread details: M39x2, right-hand (clockwise) threading for standard applications and easy maintenance of proper engagement.
• Lead type: Taper lead to gradual thread engagement, reducing starting resistance and chatter during initial cuts.
• Standard compliance: ISO 529 dimensions ensure reliable interchanges with standard nuts, collars, and components.
• Purpose: General-purpose internal thread creation and repair in a variety of metals, from steel to aluminum and cast iron.

Ideal for machinists, repair technicians, and hobbyists who need a dependable tap that starts smoothly and finishes predictably. The taper lead minimizes risk of cross-threading and binding, enabling accurate hole threading in both new work and repairs. When you’re aiming for clean, consistent internal threads without the need for coatings, this uncoated HSS tap delivers steady performance across a range of projects.

Usage tips

• Align the tap carefully with the hole and lubricate to reduce friction and wear.
• Apply steady, even pressure and rotate clockwise to engage the threads; periodically back off to break and clear chips.
• Use light to moderate tapping speed and maintain alignment to avoid thread damage.
• Keep the tap clean during use and wipe away chips after each cutting pass.

Compared with coated or specialty taps, this uncoated HSS tap emphasizes versatility and straightforward maintenance, offering reliable performance across typical workshop scenarios without special prep. It’s a solid choice when you need a proven, general-purpose tool that you can count on for consistent thread quality in M39x2 applications.
