The tap drill size for an m12 tap is 10.5mm. To use this tap drill size, you will need to measure and mark the center of the hole in the material you are going to be tapping. Then, using a 10.5mm drill bit, carefully drill the hole to the desired depth. Once the hole has been drilled, switch out your drill bit for an m12 tap and thread your piece accordingly.

What Size is an M12 Tap?

An M12 tap is a coarse thread metric machine screw tap with a size of 12mm. It has a coarse thread pitch of 1.75mm and is commonly used to create threads in metal or plastic materials [1]. The tap can be used in combination with an M12 die to create threads on rods, screws, and bolts.

What Size Hole Do You Drill for the M12 Tapped Holes?

The size of the hole necessary for an M12 tapped hole will depend on the material being used. Generally, for most metals, a 10.5mm hole should be drilled. For softer materials such as wood or plastic, a 12mm hole should be drilled. 

It is important to note that larger hole sizes may need to be drilled for deeper threads. Additionally, when drilling these holes, it is important to use a drill bit designed for the material being drilled and for the size of the tapped hole.

What is the Drill Size to Make M12 * 1.75 Tap?

The drill size to make an M12 * 1.75 tap is 10.5mm. This drill size is necessary to ensure that the hole being drilled is the correct size for the tap. It is important to note that if a deeper thread is desired, then a larger hole may be necessary in order to accommodate the additional thread depth. Additionally, when drilling these holes, it is important to use a drill bit designed for the material being drilled and for the size of the tapped hole.

What Does M12 Mean on a Tap?

M12 on a tap refers to the size of the tap. M12 is a metric thread machine screw tap with a size of 12mm and a coarse thread pitch of 1.75mm. This tap is commonly used to create threads in metal or plastic materials and can be used in combination with an M12 die to create threads on rods, screws, and bolts.

Conclusion

An M12 tap is a coarse thread metric machine screw tap with a size of 12mm and a coarse thread pitch of 1.75mm. The drill size necessary for an M12 tapped hole will depend on the material being worked with, but generally, for most metals, a 10.5mm hole should be drilled. When drilling the hole, it is important to use a drill bit designed for the material being drilled and for the size of the tapped hole. Once drilled, an M12 tap can be used in combination with an M12 die to create threads on rods, screws, and bolts.
