DRILL GUIDE
Below you will find the included tap and extractor sizes as well as the drill bits that pair with them. Select the thread
pitch you intend to tap, then match it with the drill bit size listed below. In rare cases if your material is exceptionally
thin or thick, you may need to step up (thick) or down (thin) in drill size within the pouch provided, however the
below drill bit pairings work with the majority of applications. The chart below also includes part numbers for each
piece found in this kit.
