Model:‎131-tlg Gewindereparatur Gewindereparatursatz Item Weight:‎1.65 Kilograms Package Dimensions:‎38 x 21 x 7.8 cm; 1.65 kg COMPLETE RANGE OF COMMONLY USED METRIC SPECIFICATIONS - This 131 piece set covers the five main metric thread sizes M5, M6, M8, M10 and M12. Each specification precisely matches its corresponding parameters, allowing damaged or damaged internal threads to be repaired directly without having to purchase separate models, significantly reducing costs. Wear-resistant and durable: the twist drill bits are made of titanium coated high-speed steel with a tip angle of 135°, providing high hardness and wear resistance for fast drilling and extended service life; The taps are made of high carbon steel and featuring special V-COIL thread, ensuring smooth tapping and efficient chip removal; The threaded inserts are made of stainless steel 304, offering high strength, rust resistance and corrosion protection. They are resistant to deformation and unscrewing, ensuring a high tightness of the thread after repair. RELIABLE REPAIR - Complete sets of components manufactured to professional SAE and metric double standards, characterized by high thread accuracy and superior component compatibility. The repair process creates a stronger internal thread on soft metals, effectively protecting the original thread from wear. The resulting thread has an improved load capacity compared to the original, thus meeting the requirements of industrial grade repairs. Simple operation: thanks to a clear six-step procedure, from drilling and tapping to laying inserts and break pins, no special skills are required throughout the process, which allows even novices to master it quickly. Paired with dedicated spark plug thread repair bits, it eliminates the need for pre-drilling, thus specifically addressing the major weak points of automotive repair and greatly improving maintenance efficiency. Wide Applicability: suitable for many materials and industrial sectors, it can be used on various metal substrates, including stainless steel, cast iron, aluminum alloys, steel sheet and copper. Its main applications include automotive engine repair, mechanical manufacturing, equipment maintenance, and metalworking, making it an indispensable tool for automotive shops and engineering plants.
