Threading tap KWB 443010 High-Speed Steel 70 mm 7 mm

The KWB HSS single-cut tap is manufactured from high-strength, roll-rolled high-speed steel to provide durable and precise thread cutting. It is offered in multiple metric sizes and features a precision-ground flute produced to DIN 352, making it suitable for both hand and machine tapping. With a 70 mm overall length, a 25 mm working length and a 7 mm shank diameter, the tool is intended for producing accurate internal threads in metal and plastic for workshop and maintenance tasks.

Advantages

The single-cut geometry and high-speed steel material ensure wear resistance and consistent cutting performance. Precision grinding to DIN 352 guarantees dimensional accuracy of the flute and cutting edges. The tap is designed for use by hand or with machines, providing flexibility for different working conditions and ensuring reliable thread quality.

Suitable for

• Cutting internal threads in metal components
• Forming threads in plastic parts
• Hand tapping in repair and maintenance work
• Machine tapping in production or workshop settings

How to use

Select the correct tap size for the required thread and secure the workpiece. For hand tapping, use an appropriate tap wrench; for machine tapping, ensure correct alignment and secure clamping. Apply suitable cutting lubricant for the material being threaded, start the tap square to the hole and advance using steady rotational motion. Periodically reverse the tap slightly to break and clear chips, and complete the thread by withdrawing the tap carefully.

Usage recommendations

Use cutting fluid when threading metals to extend tool life and improve chip evacuation. For plastics, use lower cutting speeds and minimal lubrication to avoid material clogging. Inspect taps for wear or damage before use and replace if cutting performance degrades.
