Don't let a stripped thread halt your project. The V-COIL Thread Repair Assortment VC80 is the professional's choice for restoring damaged or worn-out internal threads to their original size and strength. In many cases, the repaired thread is actually stronger than the original due to the high-quality stainless steel inserts. This special "111 Years Edition" covers the most common metric sizes from M5 to M12, providing a complete, high-precision ecosystem for maintenance, overhaul, and repair (MRO).
The kit features specialized STI (Screw Thread Insert) machine taps made from ground HSS-G, ensuring a perfect fit for the V-COIL inserts. Whether you are reinforcing threads in low-strength materials like aluminum or performing an emergency repair on a critical engine component, this assortment delivers industrial-grade reliability. Plus, as part of our anniversary celebration, this set includes a voucher for an exclusive VÖLKEL running shirt—perfect for those who appreciate precision both in the workshop and on the track.
