How are tap sizes measured?
Taps typically have several flutes constructed in its design. They are the grooves or valleys cut into the body of the tap. Higher numbers of flutes increase the strength of the tap and reduce space or chip flow. Thread size is the number of Threads Per Inch (TPI) which is measured along the length of the tap.
Are tap holes a standard size?
Standard taps and spouts generally require a hole of at least 22mm in diameter. Monobloc mixer taps, taking both a hot and cold supply, mostly require a minimum 32mm diameter hole.

What size drill and tap do I Need?
– The DMB is the diameter measurement you figured out above, .3125. – The full thread percentage depends on what size thread you want, typically between 70 and 85, but we’ll use 75 for this example. – The other variable, Ni, is the other part of the tap. Let’s use the 5/16″-18 tap, for instance. The Ni for that tap is 18.
What is the formula for tap drill size?
What is the formula for tap drill size? As a rule of thumb, for Metric threads, the tapping drill can be calculated by subtracting the pitch from the diameter of the thread. eg for an M5x0. 75 thread the tapping drill is 5-0.75mm = 4.25mm. For Imperial (inch) threads the tapping drill size is calculated in the same way, diameter minus pitch.
How to calculate tap drill sizes for oversized taps?
