• Uncoated HSS provides dependable performance with everyday cutting fluids, offering a practical balance between durability and affordability for shop use.
• ISO 529 dimensions ensure compatibility with standard metric threads, delivering predictable results that align with industry norms for M16x1 applications.

Ideal uses: repairing or tapping internal threads in metalwork, fabricating custom components, or maintaining equipment where left-handed threads are required. This tap is well-suited for machinists, hobbyists, and workshop professionals who demand dependable performance from a single, versatile tool.

Practical tips: pair this tap with the appropriate cutting fluid and a steady, moderate cutting speed. Start with light pressure to begin the taper lead engagement, then maintain consistent motion as the threads form. Clean chips regularly to prevent binding and extend the life of the cutting edges.
