When selecting a drill bit for a 1/4 tap, it is important to consider the material you are drilling into, the size of the tap, and the type of tap. For a 1/4 tap, the recommended drill bit size is typically 7/32 inch. This size drill bit will create a hole that is slightly larger than the tap, allowing the tap to easily cut threads into the material.
When selecting a drill bit, it is important to consider the material you are drilling into. For softer materials such as wood, plastic, and aluminum, a high-speed steel (HSS) drill bit is recommended. For harder materials such as stainless steel and titanium, a cobalt or carbide drill bit is recommended.
The size of the tap is also important when selecting a drill bit. For a 1/4 tap, the recommended drill bit size is 7/32 inch. This size drill bit will create a hole that is slightly larger than the tap, allowing the tap to easily cut threads into the material.

What size drill bit do I use for 1/4-28 tap?
The size of the drill bit you need to use for a 1/4-28 tap depends on the material you are drilling into. Generally, for a 1/4-28 tap, you would use a #7 drill bit for soft materials such as aluminum, brass, and plastic, and a #6 drill bit for harder materials such as steel. However, it is important to note that the drill bit size you use should be slightly smaller than the major diameter of the tap. The major diameter of a 1/4-28 tap is 0.250 inches, so you should use a drill bit that is slightly smaller than this. Additionally, it is important to use a drill bit that is made of the same material as the tap, as this will help to ensure that the tap will not become damaged during the drilling process.
What size drill bit do I use for a 1/4 20 tap?
The size of the drill bit you need to use for a 1/4 20 tap depends on the material you are drilling into. Generally, for a 1/4 20 tap, you would use a #7 drill bit for soft materials such as wood, plastic, and aluminum, and a #21 drill bit for harder materials such as steel. However, it is important to note that the drill bit size may vary depending on the material you are drilling into, so it is best to consult a chart or reference guide to determine the correct drill bit size for your specific application. Additionally, it is important to use a drill bit that is slightly larger than the tap size to ensure that the threads are properly formed.
