This chart includes various materials and applications, offering a quick reference for your threading needs. TAP-DRILL CHART – RECOMMEND TAP DRILL TO USE FOR 75% DEPTH OF THREADįor your convenience, we’ve compiled a comprehensive tap drill size chart for 5/16-18 taps. What size hole do I drill for a 5 16 threaded insert?ģ3/64 inches hole suitable for 5/16″ Tap. Best Cobalt Drill Bits Set for Drilling Holes in Metal.Top 12 Best Drill Bits for Metal Drilling.Top 15 Best Drill Bits for Hardened Steel.Understanding sizing differences is the first step in determining the size of drill bit you need for a 5/16′′ tap. The best-recommended drill bit size for a 5/16′′-18 tap is a 17/64′′ drill bit, also known as an F drill bit. What Size of Drill Bit Should be Used for a 5/16″ Tap? This drill size varies depending on the type of tap and the material you’re working with, making it a pivotal factor in achieving success. It is a critical component of the threading process, ensuring that threads are created with precision and accuracy. Understanding Tap Drill SizeĪ tap drill size is the diameter of the hole that needs to be drilled before using a tap. This specific size is favored for its versatility and compatibility with a wide range of materials. Practically, you may not be able to measure the drill bit diameter more than 2 decimal places. You can check fraction and decimal conversion using the below table. It refers to a tap with a nominal diameter of 5/16 inches and 18 threads per inch. When you need to convert mm to inches, you have to multiply the mm value by 0.0393701. This size drill bit should be used for drilling the initial hole that will then be tapped.The 5/16-18 tap is a widely used size in various industries and applications. Lastly, the recommended tap drill size is provided for each standard tap size. The drill size chart contains tools up to 1.5 inches in diameter, but larger tools are also commonly used.įor each thread count, the equivalent thread pitch is provided and for metric taps, the approximate thread count is shown based on the pitch. The metric system uses the thread pitch, which is the distance between threads, measured in millimeters. In the fractional and screw size systems, the thread count is used, measured in threads per inch, such as UNF threads and UNC threads. The thread spacing can be coarse or fine, will be listed after the diameter. A screw size number corresponds to a diameter which is larger for a higher screw size. Fractional sizes are listed in inches, metric sizes are listed in millimeters following the letter "M". The tap size chart is a table that lists standard size taps, specifying the diameter and thread spacing, for fractional, metric, and screw sizes. The decimal equivalents of the diameters are shown in both English and Metric units. The wire gauge and letter systems refer to tool diameters that increase as the wire gauge decreases from #107 to #1 and then continues from A to Z. Fractional sizes are measured in inches, while metric sizes are measured in millimeters. The drill size chart is a table list standard size drill bits in several measurement systems, including fractional, metric, wire gauge number, and letter. People would need a drill size chart and tap size chart to determine the proper tap drill for a certain thread size or proper tap for an existing hole. One of the most common ways to produce the thread holes is to drill a hole of the right size with a drill bit and tap it with a tap. When manufacturing custom CNC machining parts, holes with screw threads are often required for fastening the finished part or facilitating the building. What is the Drill and Tap Size Chart and Why to Use Them? When it comes to the selection of drill bit sizes and tap sizes, there are standard drill and tap size chart for reference. Drilling is a process of producing a hole while tapping is a technique used to cut a thread inside a hole, so the drill bit and tapping tool are often used in sequential to fabricate CNC parts with thread holes.
