What is a 0-80 Tap Drill Size?
Tap drills are used in metalworking to create internal threads in a hole. The size of the drill bit is determined by the size of the desired thread, which is measured in threads per inch (TPI).
The 0-80 tap drill size is one of the smallest metric tap drills, with an outer diameter of 0.0625 inches (1.59mm) and a TPI of 80. This drill bit is typically used for creating threads in very small parts, such as electronic components and miniature machine screws.
Types of 0-80 Tap Drills
There are two types of 0-80 tap drills – straight and spiral flute. Straight flute tap drills are designed for cutting straight threads, while spiral flute tap drills are designed for cutting tapered threads. Both types are available in a variety of materials, including high-speed steel (HSS), cobalt, and titanium.
Benefits of 0-80 Tap Drills
Using a 0-80 tap drill has several benefits. First, it is very precise and allows for accurate threading. Second, it is relatively small, making it suitable for creating threads in delicate parts.
Third, the small size and high TPI of the 0-80 tap drill allow for threads that are stronger and more durable. Finally, the small size of the 0-80 tap drill means it is easy to maneuver in tight spaces.
How to Use 0-80 Tap Drills
Using a 0-80 tap drill is relatively simple. Start by ensuring that the hole is the correct size for the desired thread. If the hole is too large, the thread may not fit correctly. Once the hole is the correct size, insert the tap drill into the hole and turn the tap drill in the same direction as the thread.
Make sure to cut slowly and apply light pressure to the tap drill. When the desired thread depth is reached, remove the tap drill from the hole and the thread is complete.
