Taps are used to create the inner part of a surface in a hole using a calibrating tool. It creates the female part of the mating pair. The process of creating the female threads is referred to as tapping. Here are proper techniques to keep in mind when using metric taps. UseWhen using a tap, you can use it manually or you can use a wrench or mechanical drill. When using a wrench, ensure that the wrench matches the tap you are using to prevent too much tension that can result in breakage of the tap. LubricationWhen forming metric thread taps, ensure that there is proper lubrication, otherwise it could lead to the tap wearing out much faster. Oil is essential as it makes it prevents the tap from becoming dry and easily breakable. It will also make it easier for you to tighten the screw without too much difficulty. Proper CalibrationBefore starting to make threads, it is essential to ensure that the hole has been properly calibrated. In some cases, some manufacturers sell the taps together with their corresponding drill bits and wrenches. This will make it much easier for you to thread the hole.
