• Second lead design for faster tapping – the double-start geometry engages material more quickly per revolution, speeding up production and improving chip evacuation in through-holes.

• High-speed steel, ground finish, uncoated – delivers crisp thread forms with durability, while the uncoated surface accommodates a wide range of cutting fluids and materials.
• Square driving shank for secure wrench fit – the square end accepts standard tap wrenches, providing stable alignment and torque transfer during operation.
• Versatile general purpose tapping – ideal for threading holes in steel, cast iron, aluminum, brass, and other common machinable metals in repair, fabrication, and maintenance workflows.
• Practical usage guidance – pair with appropriate cutting fluid, drill the correct pilot hole per ISO guidelines, maintain steady pressure, and back off to break chips to prevent binding and reduce wear.
