VOLKEL 04081 M5 - M12 V-COIL Thread Repair Workshop Kit

VOLKEL 04081 M5 - M12 V-COIL Thread Repair Workshop Kit

• M5-12 Manual thread repair kit using V-Coil thread inserts. The V-Coil thread inserts are manufactured from precision profiled, high quality, austenitic, chromium nickel, stainless steel wound into a helical spiral. The V-Coil inserts have a spring like appearance and once fitted their position is maintained by the action of radial pressure between their coils and the flanks of the tapped hole. This pressure exists because the free diameter is larger, by a calculated amount, than the installed diameter. Their unique design ensures that once installed using either manual or automatic tools they provide strong permanent internal threads resistant to both heat and corrosion. The workshop set includes the following items for each of M5, M6, M8, M10 and M12 threads: drill for clearing damaged thread, special V-Coil tap for cutting the holding thread into the cleared hole, thread insert installation tool and tang removal tool plus 25 V-Coil inserts for each size except M12 - 10 inserts only.
