This is done with a standard drill, the size of which is indicated on the coilthread chart. The hole is then tapped with an oversize tap. The free diameter of the coil-thread insert is larger than the new threaded hole, but it is easily “wound” into place with the inserting tool provided. Once in place, the insert tends to spring back to its original diameter, giving it a very strong grip in the hole. Finally, the driving tang is broken off by tapping downward with the end of the inserting tool. If necessary, inserts can be removed, using one of the extracting tools shown on the next page. Permanent, wear-resistant, corrosion resistant Stainless Steel inserts.
