Where this product is used

Used wherever internal metric threads need to be cut in workshops, machining centres, and on-site maintenance operations.

• Cutting internal metric threads in ferrous and non-ferrous metals, plastics, and composite materials in manufacturing and engineering workshops.
• Spiral flute taps used in blind holes where chip extraction upward is essential; spiral point (gun) taps used in through-holes where chips can clear ahead.
• Machine tapping on CNC machining centres, drill presses, and tapping machines for high-volume production threading.

Selecting the right option

Choose spiral flute (R-type) for blind holes and softer materials where chip removal upward is required. Choose spiral point (gun) taps for through-holes in steel and cast iron where chips can be pushed ahead. Choose forming (roll) taps for ductile materials — they displace rather than cut, producing stronger threads. Match the HSS grade and coating to your material: standard HSS for general use, HSSE V3 or PM-HSS cobalt for harder or more abrasive materials.
