When it comes to drilling holes for taps, knowing the drill size is a must. Knowing the right drill size for a particular tap is important for achieving success when it comes to tapping a hole.

In this blog post, our engineers will discuss the 12mm tap drill size and its drill bit size. We’ll also cover the drill size for the M12 tap, and what size hole do you drill for M12 tapped holes? We’ll also review the metric table and drill bit size table, and explain why knowing your drill sizes are important.

What is a 12mm Tap Drill Size?

The 12mm tap drill size refers to the size of the drill bit that you need to use to create a hole for a 12mm tap. The 12mm tap is a metric tap, and you will need a drill bit of the same size in order to create the hole. The tap drill size for a 12mm tap is 9.5mm.

What is the Drill Size for M12 Tap?

The drill size for an M12 tap is 9.5mm. This size is necessary in order to create the hole that the tap will thread into. It is important to use the correct size drill bit so that the tap will be able to thread properly into the hole.

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

In order to create the hole for the M12 tapped holes, you will need to use a 9.5mm drill bit. This is the same size as the tap drill size for a 12mm tap. It is important to use the correct size drill bit so that the tap is able to thread properly into the hole.

If you are not sure what size drill bit to use with a particular tap, you can refer to a metric table or drill bit size table. These tables will provide the size of the drill bit that you need to use in order to create a hole for a specific tap.

Importance of Knowing Your Drill Sizes 

Knowing your drill sizes is important because it ensures that the tap is able to thread properly into the hole. If you use the wrong size drill bit, the tap may not be able to thread properly, and this can lead to a variety of problems.

Additionally, using the wrong size drill bit can cause damage to the tap, which can lead to expensive repairs or replacements.

Conclusion

Knowing the correct drill size for a particular tap is important for achieving success when it comes to tapping a hole. The 12mm tap drill size is 9.5mm, and you will need to use an 8.5mm drill bit in order to create the hole for the 12mm tap.

Referring to a metric table or drill bit size table can help you determine the size of the drill bit that you need to use. Knowing your drill sizes is important because it ensures that the tap is able to thread properly into the hole.
