Key features that matter

• Bottom lead design: facilitates easier entry and steadier alignment, especially in deeper holes, reducing chatter and improving first-pass accuracy.
• High-speed steel, ground finish: delivers precise thread form with reliable cutting action and efficient chip evacuation.
• Uncoated for versatility: works well with standard cutting fluids and across common metals without interference from coatings.
• ISO 529 compliant: ensures the M26x1.5 right-hand thread conforms to global metric standards for compatibility with a wide range of components.
• Right-hand thread, general purpose: ideal for routine tapping tasks in mechanical assemblies, repairs, and prototyping.

Ideal uses and scenarios

This tap is suited for threading through-holes and repairing damaged threads in steel, aluminum, brass, and other machinable materials. Use with a tap wrench or drill press setup, paired with appropriate lubrication. The M26x1.5 size is a common choice in automotive, machinery, and fabrication projects where strong, reliable metric threads are required.

How to use for best results

• Drill the correct pilot hole in accordance with ISO 529 guidelines for M26x1.5.
• Apply cutting oil or a suitable coolant to reduce friction and improve surface finish.
• Begin tapping with light, steady pressure, maintaining perpendicular alignment to the workpiece.
• Periodically back off to break and remove chips, then continue to the full thread depth.
• Deburr and clean the threaded hole after tapping to ensure smooth assembly.
