BaerCoil Thread Repair Kit M 5 x 0.8 for blind holes
With this BaerCoil® thread repair set it is possible to repair blind hole threads in M 5 x 0.8.
BaerCoil® thread inserts are the best solution for all your thread repair needs! With them you are able to make durable and strong connections. With the inserts you avoid scrap in your components and can recycle them. The inserts are precise and wear resistant - your screw will stay firmly in place without the thread insert slipping out.
The BaerCoil® thread insert is the perfect solution for damaged threads without changing the nominal diameter. For the thread repair with wire thread inserts, the thread is drilled out and a new STI thread (screw thread insert) is cut for the wire thread insert. This thread is often also called STI thread (STI=Screw Thread Insert). Then the BaerCoil® thread insert is screwed into the old thread and thus the workpieces are screwed back together. With BaerCoil® thread inserts, the thread produced is significantly more stable than the original thread.
Our thread inserts ensure that both static and dynamic work loads are distributed evenly over the individual thread turns. In addition, the flexibility of the thread inserts compensates for possible pitch and angular errors, so that optimum force transmission from the bolt to the nut thread is achieved. Especially in lightweight constructions, BaerCoil® thread inserts help to save carrier material and to use smaller or shorter screw connections. They are already an important component in aviation and vehicle construction. They significantly save material and contribute to the conservation of resources.
For repair directly on the thread, this thread repair kit contains various auxiliary tools, such as the core drill bit, taper countersink, blind hole machine tap with oversize for insert thread, insertion tool, tang breaker and wire thread inserts made of stainless steel. This "blind hole"thread repair set contains thread inserts in three different lengths and a machine tap with spiral flutes that convey the chip upwards out of the hole when thread cutting.
BaerCoil® thread inserts can be shortened with a side cutter or similar if necessary, according to the required length.
