Metric Tap Drill Chart - Handy Reference for International Threads

If you're working with bolts and metric threads, having a tap drill chart on hand is absolutely essential. A tap drill chart is a reference tool that helps you determine the appropriate drill bit size to use when tapping a hole for a bolt or screw. At BizzLibrary.com, we offer a tap drill chart in PDF format, available for download to help make your projects run smoothly and efficiently.

Understanding Tap Drill Charts

Tap drill charts provide an essential reference for those working with threaded bolts and screws. When tapping a hole, it's critical to choose the right drill bit size to ensure a proper fit. Using the wrong bit size can result in stripped threads or weakened connections, potentially leading to equipment failure or other issues.

Tap drill charts typically include information for both metric and imperial threads, and indicate the correct drill size based on the diameter and pitch of the thread. The charts may also include additional information, such as recommended torque values, material strength ratings, and other technical specifications.

How to Use a Tap Drill Chart

To use a tap drill chart, follow these simple steps:

1. Determine the Thread Size: Measure the diameter of the bolt or screw using a caliper or thread gauge to determine the thread size and pitch.
2. Refer to the Chart: Using the thread size and pitch, locate the corresponding values on the tap drill chart. The chart will indicate the correct drill bit size to use.
3. Select the Drill Bit: Choose the recommended drill bit size indicated on the chart and insert it into a drill chuck.
4. Drill the Hole: With the correct drill bit size, drill a hole into the material at the appropriate depth to match the length of the threaded section of the bolt.
5. Tap the Hole: Using a tap tool, carefully thread the hole to create the threaded section for the bolt or screw.
6. Insert the Bolt: Once the hole has been tapped, insert the appropriate bolt or screw and tighten as needed using an appropriate torque wrench.
