3/4-10 UNC-2B Drill Size: Understanding the Specifications
When it comes to drill sizes, it's essential to understand the specifications to ensure accurate and efficient drilling operations. One of the most commonly used drill sizes is the 3/4-10 UNC-2B drill size. In this article, we'll delve into the details of this drill size and explore its applications.
What does 3/4-10 UNC-2B mean?
The 3/4-10 UNC-2B drill size can be broken down into several components:
- 3/4: This represents the nominal diameter of the drill bit, which is 3/4 of an inch or 19.05 mm.
- 10: This refers to the number of threads per inch (TPI) of the drill bit. In this case, the drill bit has 10 threads per inch.
- UNC: This stands for Unified National Coarse, which is a thread series standard used in the United States and Canada. UNC threads are commonly used for bolts, nuts, and screws.
- 2B: This represents the thread class, which is a measure of the thread's tolerance and accuracy. In this case, the 2B thread class has a medium tolerance.
