What drill size should be used for M10 tapping?

Thread Drill size for tapping standard metric threads Drill size for tapping fine metric threads
M10 8.5 8.8
M12 10.2 10.8
M14 12 12.5
M16 14 14.5

### How do I know what size hole to drill for tapping?

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.

What is the diameter of a 10-32 Tap?

4.8mm
The main difference between 10-32 and 12-24 threads is their dimensions. 10-32 screws have a diameter of 3/16″ (4.8mm) where as 12-24 screws have a diameter of 7/32″ (5.6mm).

How to calculate the size of a tap drill hole?

See equation: M6 – (1.2990 X 75) = (6 – .9743) = 5.0257mm To figure whether or not pitch is too coarse for diameter: (Double thread depth) X 3 = x x = the smallest diameter possible for that T.P.I. % of Full Thread* X mm Pitch 76.98 TAP DRILL SIZES – INCH & METRIC with DRILL SIZE FORMULAS (cont.)

### How does the tap size chart work in machining?

The tap size chart provides a list of standard size taps, specifying the diameter and thread spacing, for fractional, metric, and screw sizes. The decimal equivalents of the diameters are shown in both English and Metric units. Fractional sizes are listed in inches, while metric sizes are listed in millimeters following the letter “M”.

What’s the drill bit size for a thread hole?

For each thread count, the equivalent thread pitch is provided and for metric taps, the approximate thread count is shown based on the pitch. Lastly, the recommended tap drill size is provided for each standard tap size. This size drill bit should be used for drilling the initial hole that will then be tapped.
