A 3/8 tap will require a drill bit with a diameter of 0.375 inches, or 9.5 mm.
If you’re looking to drill a hole for a 3/8 tap, then you’ll need a drill bit that is slightly larger than the tap itself. The exact size will depend on the specific tap, but generally speaking, you should use a 3/16 or 7/32 drill bit. With these sizes, you should be able to create a hole that is big enough for the tap to fit through without being too loose.

What are the Best Drill Bits for Tapping 3/8-Inch Threads
When it comes to drilling holes, there are a variety of drill bits available on the market to choose from. But what are the best drill bits for tapping 3/8-inch threads?
Let’s take a look at some of the things you need to consider when choosing the best drill bit for your needs.
Drill Bit Material
One of the first things you need to consider when choosing a drill bit is the material it is made from. The most common materials used for drill bits are high speed steel (HSS) and cobalt steel.
HSS is the most affordable option and is great for general purpose drilling. Cobalt steel is more expensive but offers better heat resistance and durability, making it ideal for drilling tougher materials.
Drill Bit Size
request specific sizes depending on the project you’re working on. For example, if you’re tapping 3/8-inch threads, then you’ll need a 3/8-inch or larger drill bit. It’s important to note that not all Drill Bit sizes will be available in HSS or Cobalt Steel so keep that in mind when making your selection.
Drilling Speed
Another thing to consider when choosing a Drill Bit is the speed at which it can rotate while still maintaining precision. This will be dependent on both the power of your Drill as well as the type of material you’re trying to Drill through.
If you’re working with harder metals, then you’ll need a slower speed to avoid damaging your workpiece or breaking your Drill Bit.
Cooling Methods
It’s also important to consider how your Drill Bit will be cooled during use as this can affect its lifespan and performance.
Some methods include using Cutting Fluid, circulating coolant through hollow Drill Bits or simply letting air pass over the surface of hot Bits .
Now that we’ve gone over some factors to keep in mind when selecting a Drill Bit, let’s take a look at three popular options for tapping 3/8 – inch threads:

What Size Drill Bit for a 3/8 16 Tap
When choosing a drill bit size for a 3/8-16 tap, it is important to consider the type of material being tapped, the pitch of the tap, and the thread depth. For example, if you are tapping into soft materials such as wood or plastic, you will want to use a smaller drill bit. If you are tapping into harder materials such as metal, you will want to use a larger drill bit.
The pitch of the tap also plays a role in determining the size of drill bit to use. A higher pitch tap will require a smaller drill bit while a lower pitch tap will require a larger drill bit. Finally, the thread depth also affects the size of drill bit needed.
A shallow thread depth will require a smaller drill bit while a deep thread depth will need a larger drill bit. In general, it is best to err on the side of using too large of a drill bit rather than too small as it is easier to make adjustments with a larger hole than it is with a smaller one.
What Size Drill Bit for 3/8 Bolt
If you’re looking for the answer to the question, “What size drill bit for 3/8 bolt?”, then you’ve come to the right place. In this blog post, we’ll provide detailed information about drill bits and bolts so that you can make the best decision for your project.
When it comes to selecting a drill bit, there are many factors to consider.
The first is the material of the item you’re drilling into. If it’s a softer material like wood, then you won’t need a very large or powerful drill bit. However, if you’re drilling into something harder, like concrete or metal, then you’ll want to choose a larger and more powerful drill bit.
Another factor to consider is the size of the hole you need to create. Obviously, the bigger the hole, the bigger the drill bit you’ll need. And finally, think about how much power your drill has.
If it’s not very powerful, then you won’t be able to use a large or powerful drill bit without damaging your drill or breaking your project piece.
Now that we’ve gone over some general considerations, let’s talk specifically about 3/8 bolts. For most projects involving a 3/8 bolt, we recommend using a 1/2″ diameter Drill Bit .
This will give you plenty of power and will create an appropriately sized hole for your bolt.
3/8-16 Tap Drill Size in Mm
When it comes to taps, there are two main types: taper taps and plug taps. Taper taps have a tapered end that gradually becomes larger in diameter, while plug taps have a cylindrical end with the same diameter as the rest of the tap. The size of the tap drill bit you’ll need to use depends on which type of tap you’re using.
For a taper tap, you’ll need a drill bit that is slightly smaller in diameter than the small end of the tap. For instance, if you’re using a 3/8-16 taper tap, you would need to use a 7/32 inch (5.5 mm) drill bit. As for plug taps, you’ll need to use a drill bit that is equal in diameter to the body of the tap minus the thread pitch.
So, for a 3/8-16 plug tap, you would need to use a 11/32 inch (8.7 mm) drill bit.
Keep in mind that these are just general guidelines – be sure to consult your specifictap’s instructions for more precise information on what size drill bit to use.
3/8 Tap Drill Size in Mm
3/8 Tap Drill Size in Mm:
When it comes to choosing the right tap drill size for your project, there are a few things to keep in mind. First of all, it’s important to know the basics about taps and their corresponding sizes.
A 3/8 tap, for example, is going to be a lot different than a 1/4 tap. With that said, here is some more information on 3/8 tap drill sizes in mm so you can make the best decision for your project:
The first thing you need to know is that there are two types of standard taps- metric and imperial.
Metric taps are going to be measured in millimeters (mm), while imperial taps will be measured in inches (in). It’s important to use the correct type of tap when measuring your drill size because they aren’t always interchangeable.
For instance, a 3/8 metric tap has a 9.525 mm diameter, while a 3/8 imperial tap has a 9.749 mm diameter.
This difference might not seem like much but it can make a big difference when trying to create threads that fit properly. In general, you want your drill bit size to be as close as possible to the actual thread size- within 0.5 mm or so.
Now that we’ve got that out of the way, let’s take a look at what kind of drill bit you’ll need for a 3/8 metric thread tapping operation using various materials…
-For steel or iron: Use an HSS (high speed steel) twist drill bit with 118 degree tip angles and split points . The most common choice would be an 11/32 or 7mm bit but depending on the specific application other sizes may also work such as 5/16 or 8mm bits.-For stainless steel: Same as above but due to its harder nature stainless steel requires slightly sharper bits with higher cutting speeds and feed rates .
You may also encounter difficulties with chip breaking and removal so consider using spiral fluted bits instead which help evacuate chips more effectively.
5/16 Tap Drill Size in Mm
When it comes to tapping holes, the 5/16 tap drill size in mm is a popular choice for many applications. This size drill bit is used to create threads in materials such as metal and plastic. It can also be used on softer materials such as wood.
The most common use for the 5/16 tap drill size in mm is to create tapped holes for screws. This size drill bit is also commonly used to create pilot holes for larger diameter taps.
The number “5” in the name of this drill bit refers to its standard metric size, while the “16” refers to the thread count or TPI (threads per inch) that it produces.
In terms of actual measurements, the 5/16 tap drill size in mm translates to 7.9mm. This specific metric conversion means that this particular tap drill will produce threads that are just under 8mm in diameter. The smaller tapping sizes like this one are sometimes referred to by their decimal equivalent rather than their millimeter measurement; therefore, you may also see this same tap drill referred to as 0.3125” or 3/32” instead of 5/16” (7.9mm).
While the vast majority of screws will fall within what is considered an acceptable range for a hole created by a 5/16” bit, there are always exceptions depending on the application requirements and type of screw being used For example, if you need a very snug fit or are using particularly thin-walled screws, then you might want go with a slightly smaller pilot hole – such as 3/32” (2.4mm) – which would still be large enough for most general purpose screws while providing a tighter grip..
3/8-24 Tap Drill Size
3/8-24 is the tap drill size for a 3/8-24 thread. This is a standard size for many screws and bolts. You can find this size in both metric and imperial measurements.
To find the right tap drill size for a 3/8-24 thread, you need to know the major diameter of the thread. The major diameter is the outside diameter of the thread. The 3/8-24 tap drill size has a major diameter of 0.375 inches (9.525 mm).
Tap Drill Size Calculator
When it comes to drilling holes, there are a lot of things that you need to consider. One of the most important things is the tap drill size. This is the size of the hole that you need to drill in order to accommodate the tap.
There are a lot of different factors that go into figuring out the right tap drill size. But don’t worry, there’s a calculator for that! With a little bit of information, you can easily find the right tap drill size for your project.
First, you’ll need to know the major diameter and pitch of the thread that you’re using. The major diameter is simply the outside diameter of the thread. The pitch is how many threads there are per inch (or metric equivalent).
With those two pieces of information, you can plug them into the calculator and it will do all the work for you!
Once you have your tap drill size, all that’s left is to grab your drill and get to work!
Conclusion
3/8″ is the most common size of drill bit used to create a starter hole for a tap. The size of the drill bit is determined by the size of the tap. A 3/8″ tap will require a 3/8″ drill bit.
