Hand Tap Set Bohrcraft 4100, HSS-G, DIN 352, 3 pcs

Hand Tap Set Bohrcraft 4100, HSS-G, DIN 352, 3 pcs is engineered for precise internal thread cutting in materials with tensile strength up to 800 N/mm². This set is manufactured to DIN 352 standards and uses high-speed steel ground (HSS-G) for consistent performance. The three-piece configuration covers all threading stages, supporting both through and blind holes for metric ISO threads according to DIN 13.

The set includes a rougher (No. 1), intermediate (No. 2), and finisher (No. 3), each designed for a specific stage of the threading process. This sequential approach helps reduce cutting force and improves thread quality. The taps are suitable for a wide range of general engineering and maintenance tasks, particularly where precise and reliable thread formation is required.

With its robust HSS-G construction, the Bohrcraft 4100 Hand Tap Set is compatible with various machinable materials, making it a practical choice for workshops and production environments. The design supports both through-holes and blind holes, offering flexibility for different threading scenarios. Each tap is clearly marked for its stage, ensuring correct usage and workflow.
