Tap drills are essential tools for creating threads in a range of materials, from wood and metal to plastic and composite. One of the most commonly used sizes is the 3/8 inch pipe tap, which is used to create threads in pipes to connect and seal them.

However, choosing the right drill size for a 3/8 pipe tap can be a tricky task as there are a number of factors to consider. So in this article, our engineers will take a look at the 3/8 pipe tap drill size and everything you need to know about drilling a hole for it.

3/8 Pipe Tap Drill Size

The drill size for a 3/8 inch pipe tap is typically 29/64th of an inch. This is the recommended drill size for a 3/8-inch pipe tap in both metal and wood.

To ensure accuracy, always use a drill bit that is one size larger than the desired thread size. In other words, the drill bit should be slightly larger than the 3/8 inch tap to create the correct size thread.

What Size of Drill Bit to Use for a 3/8 Pipe Thread Tap?

When drilling for a 3/8-inch pipe tap, you should use a 29/64th-inch drill bit. This is the recommended size for both metal and wood applications. For steel, you should use high-speed steel (HSS) drill bit, as it is more durable. For softer materials such as wood, a standard twist drill bit is suitable.

What Hole Size Do I Need for a 3/8 Pipe Tap?

A 3/8 inch pipe tap requires a hole with a diameter of 29/64th of an inch. This is the recommended size for both metal and wood applications. It is important to note that the hole should be slightly larger than the desired thread size so that the tap can cut the threads correctly.

Conclusion

Choosing the right drill size for a 3/8-inch pipe tap is an important task. The recommended drill size for a 3/8 inch pipe tap is 29/64th of an inch for both metal and wood applications.

It is important to use a drill bit that is slightly larger than the desired thread size to ensure accuracy. With the right drill size and the correct technique, you can create perfect threads in pipes with ease.
