May 31st, 2024By E-Z Lok

If you’ve ever wondered how professionals achieve such precise installations of threaded inserts, the answer lies in the use of drill and tap charts. These handy references are essential for selecting the exact drill and tap sizes needed for any project, ensuring that each insert fits perfectly. These charts save time and prevent costly errors by eliminating the need for guesswork. With a tap drill chart, achieving the precision needed for your work is straightforward and reliable.

In this guide, we will explore how drill and tap charts can help you drill more efficiently and why they are important.

How to Use E-Z LOK Drill Charts

Navigating the E-Z LOK drill chart is straightforward and significantly enhances the installation process for threaded inserts. Whether you are working with wood, metal, or plastic, these charts are essential tools for identifying the precise drill sizes required for each material type. Understanding the importance of precise drill and tap sizing is fundamental in maximizing the benefits of your threaded inserts.

Using a hole that’s too small can lead to threading difficulties or even damage to both your insert and the material. Conversely, a hole that’s too large won't allow the insert to hold properly, compromising the stability and strength of the assembly. Ensure you use our drill and tap chart to select the exact size needed for optimal performance and durability. Achieving this balance is crucial for reliable and long-lasting results.

Here's a detailed look at how to use these invaluable resources effectively:

FAQs About Drill and Tap Charts

If you have questions about our drill and tap charts, we want to help. That is why we have answered a few of the most common questions we hear below.

What Size Drill Bit Should I Use for Wood Inserts?

For wood inserts, use the recommended drill bit size shown on the packaging, our website, and our drill chart. Selecting the correct bit size helps prevent issues that might compromise the insert’s hold.

How Do I Choose a Drill Size for Metal Inserts?

Choosing the proper drill size when installing inserts in metal is critical for proper tap performance when tapping the hole prior in installation. An undersized hole can cause the tap to break. An oversized hole can keep the insert adhesive from activating properly and compromise the performance of the insert.

Can I Use the Same Drill Bit for Different Materials?

No. Different materials require specific drill sizes to ensure optimal installation and hold of the inserts. For example, wood, metal, and plastic requirements vary significantly. Each material's density and properties necessitate a particular approach, as specified in our comprehensive drill size for threaded inserts chart.

What If the Insert Doesn’t Fit After Drilling?

If an insert does not fit after drilling, it is vital to check if the drill size matches our drill chart's recommended size. Using the exact recommended size is essential to avoid issues like loose fits or damage to the insert and material. If discrepancies occur, re-evaluating the drill bit size against our recommendations might resolve the fitting issue.
