A Brief Note on Drill and Tap
The combination of Drills and Drill Bits allow you to make holes in wood, bricks, concrete, metal and other materials. If you want to insert screws or bolts into these holes, then you need proper threaded walls on the holes. This is where a ‘Tap’ comes into play. It is a tool that can create screw threads in holes created by drills. The process of creating threads in drill holes is known as Tapping.

Conclusion
If you want to create screw threads in holes, hen you have to use a Tap (a tool that forms threads). And the process of creating these threads is known as Tapping. Since tapping and Drilling are closely related to each other, if you want to tap a hole, then the diameter of the hole is very important. This is where the Tap Drill Chart can be handy. You can use these charts as a reference to properly drill holes and tap them. Comment * Name * Email * Website
