Planning a DIY project involving a ¾” tap? Lean on my years of experience to find the perfect drill bit size. I’ll unravel the key aspects – from identifying the right tasks for a tap to considering the ideal length for your drill depth. Let’s get started!

What Size Drill Bit for ¾” Tap?
For a 3/4″-10 tap, you will need a 21/32″ drill bit, and for a 3/4″-16 tap, you will need a 11/16″ drill bit.
| Tap Size | Drill Bit Size |
|---|---|
| 3/4″-10 | 21/32″ |
| 3/4″-16 | 11/16″ |
Now that you know the important details, let’s discuss more. There is usually one standard length for 59/64” drill bits. They usually measure out at around six inches.
Some of the other things that you need to focus on are the screw size, the drill diameter, and the drill bit size. With a ¾” tap, there are two screw sizes that are available along with the drill diameter and their corresponding bit size.
Other common Tap sizes you’ll need to know are a 8/32″ Tap, 5/16″ Tap, 3/8″ Tap, 7/16″ Tap, 1/2″ Tap, and 5/8″ Tap.
| Screw Size | Drill Diameter | Drill Bit Size |
| ¾” 10 Tap | .6562 | 21/32“ |
| ¾” 16 Tap | .6875 | 11/16“ |
How to Use ¾” Tap?
Tap drills are used for drilling through different types of metal. Before going any further, it’s important that you have the right measurements in place. This includes the screw size, drill diameter, and the drill bit size.
Anything ill-fitting will turn what could be a successful project into a disaster. Insert the drill bit into the chuck and tighten it so that it is properly secured. Once everything seems to be nice and secure, you can drill a hole through the metal.
Preparation is important. I’ll discuss that when I got into the consideration section of this guide.
- Once you have the bit installed, drill the hole of the desired size. It would also help if you made a divot using a center punch to mark the site of the drill.
- Also, lubricating it with drilling oil will make the process a lot smoother. After this, place the end of your drill bit into the divot. Begin to drill at a slow speed and make sure to apply enough pressure to where it can slowly penetrate the metal.
- A slow speed will allow for better grip and an easier time for the drill bit to pierce through the metal. Make sure that the drill bit is in a straightened position. The tap you will be installing will need a straight hole.
- After you slowly drill the hole, be sure to keep applying the pressure. As you lift up the bit, make sure you speed it up to medium. Try not to push too hard as it can cause damage to the bit.
- You should consider removing the drill for every inch of depth to clean off any of the flakes or debris that is being created. Repeat the process until the bit completely pierces through the metal.
- While a handheld drill can be used, a metal drill press will prove itself useful if you are looking for the best result.
- After this, you can install the screw using your T-handle. Be sure to lubricate the hole before doing so.
When to Use ¾” Tap?
The best time to use a ¾” tap is when you are drilling holes into metal. From there, it will also be used for when you need to install screws based on the size listed above on the chart. You’ll want to make sure you are using the proper drill.
This can include a corded drill, cordless drill, or even a drill press. It depends on the project and the other equipment you plan on using such as a clamp to secure the metal piece.
Other Considerations for ¾” Tap
You’ll want to consider what you need for the preparation process. For example, the type of drill you need. As mentioned earlier, using a drill press could yield better results compared to handhelds.
However, you could use a cordless or corded drill. If the project is a bit more challenging, you’ll want something more powerful. At this point, a corded drill or a drill press will be good options. Especially if you are planning on drilling through thicker pieces of metal.
It would also be a good idea to have drilling oil on hand. This will be used to lubricate the holes throughout the entire process. Plus, it makes the job a lot easier compared to not using it.
Whether you are new to drilling or a seasoned vet, drilling oil is your friend. Especially when you need to install the screw after drilling.
Before Using a ¾” Tap
Make sure that you have the right measurements including the bit size, drill size, and screw size. Everything has to be on point. Double check your measurements before continuing.
When marking holes, always use a center punch since it will be enough to penetrate a small hole through metal materials. Know where to add a divot so you know exactly where to drill. Also, use a vise to safely secure the metal piece you are drilling.
Conclusion
I hope that you find this guide for finding a drill bit size for your ¾” tap handy. You may be able to choose the right drill bit depending on the screw size that you plan on using. Drilling through metal is something that can’t be done with no ordinary drill bit.
It has to be tough enough and at the right size. Plus, with a powerful enough drill, it will be enough for the bit to pierce through easily without any issue. For all your metalworking needs, there’s a tap and drill set that will fit the 3/4 “ tap and their corresponding bit sizes.
