Wiseman Threading Tools Spiral Point Metric HSS Tap (Right Hand) – M30x2 is a high-speed steel ground thread tap designed for fast, precise internal threading in steel and other machinable metals. Uncoated and general purpose, this tap adheres to ISO 529 dimensions to ensure accurate, consistent threads every time.

• Spiral point (gun nose) design pushes chips forward, enhancing performance in through-holes and reducing the risk of chip binding or clogging.
• Right-hand thread for standard metric internal threads; rotate clockwise to cut cleanly and reliably.
• Material and finish — High-speed steel, ground to tight flute geometry for strong cutting action; uncoated for compatibility with a wide range of cutting fluids and coolants.
• ISO 529 compliant — ensures consistent thread form and pitch across components that require standard M30x2 threads.
• Size and compatibility — Metric M30x2 thread, suitable for a broad spectrum of steels and machinable alloys in workshop environments.

This tap excels in applications where robust internal threads are required in through-holes or through-channel components. The spiral point geometry accelerates threading by directing chips ahead of the cutting edge, reducing dwell time and tool wear when used with proper lubrication.

Ideal use scenarios include repairing or fabricating engine blocks, motor housings, machine frames, and other metal assemblies where precise, standard M30x2 internal threads fit standard fasteners and nuts. It’s a dependable choice for shops that value repeatable results and long service life from a single, uncoated HSS tool.

Practical tips for best results:

• Consult the tapping drill size chart for M30x2 and select the recommended drill diameter to ensure optimal thread engagement.
• Apply cutting oil or threading fluid to improve finish quality and extend tap life.
• Secure the workpiece firmly and use a tapping fixture or guiding drill to maintain alignment and prevent deflection.
