M10×1.5 is a fairly thread identity that you'll always come across, but in the real term, what do the numbers and letters mean.

Let's begin with M10. "M" denotes that it is a metric thread. The number "10" is the minor outside the diameter of the thread.

Look into the major diameter Of a Thread

M10 thread with various pitches and 1.5 happens and appears to be the thread pitch, i.e., the distance that's in between one pointy bit of a thread and the next one along. There are some top one that is 1.5, which is somewhat standard.

Mostly, the braking system of motorcycles is a place where finer threads are popularly used. So if a bolt doesn't fit in properly, do well to check that you're making use of the right pitch.

One last thing you need to know and understand is the internal diameter of a metric thread, which is known as Minor dia. M10×1.50 is approximately 8.50mm. This diameter specifies the size of tapping that's being used.

HAND CUTTING METRIC THREAD

To chip or cut an internal thread, you will need a pair of taps of the correct thread pitch and size. Typically, metric thread taps are stocked as a pair of three assigned taper, bottom, and second.

You'll also need a tap available to turn the tap, and there are a couple of designs.

Now, when tapping a blind hole, the hike requires slight drilling that's deeper than the thread length that's required. You start by tapping the taper tap and make sure that as you do that, you're cutting straight to the top surface of your work. And after every half turn, reverse your direction to break up the chips.

Now for a blind hole, periodically remove the tap completely and clear the chips out of the hole. When the tapers get to the bottom of the hole, repeat that procedure with the second and bottoming taps.

Through the holes, you will need the taper and second tap to complete the thread. The process of cutting paste or fluid will lessen the process. Tread carefully, breaking a tap off during your work creates a full world of grief.

Before you can do any of that, you'll need to drill the exact size hole. For instance, producing a threaded hole for M10×1.5 bolt to screw in would need a hole of 8.5mm diameter and tap with the necessary taps.

If the same bolt used is needed to pass through a hole, then the drill of 10.2mm diameter would be made use of appropriately.
