When working with tap bits, one of the most frustrating experiences can be having the bit snap off inside the material you’re drilling into. This situation can seem like a disaster, especially if you’re on a tight deadline or working with expensive materials. However, with the right techniques and tools, it’s often possible to remove the snapped tap bit and salvage your project. In this article, we’ll explore the steps and methods for removing a snapped tap bit, ensuring you can get back on track with minimal delay.
Understanding the Challenge
Before diving into the removal process, it’s essential to understand the nature of the problem. A tap bit is designed to create threads in a material, allowing for the insertion of screws or other threaded fasteners. When a tap bit snaps, it usually does so because it has been subjected to excessive torque or because the material it’s being used on is too hard. The snapped portion of the bit can become stuck in the threading it was creating, making it difficult to remove without damaging the surrounding material.
Evaluating the Situation
The first step in removing a snapped tap bit is to evaluate the situation carefully. Assess the material you’re working with, as different materials may require different approaches. For example, removing a snapped tap bit from wood might be simpler than doing so from metal. Consider the depth and location of the snapped bit, as well as the tools and resources you have available. This initial assessment will guide your approach and help you decide on the best method for removal.

Extraction tools, such as tap extractors or Easy Outs, are specifically designed for removing broken taps and drill bits. These tools work by being screwed into the broken tap, where they then ‘bite’ into the metal, allowing for the removal of the broken piece. Using the correct size of extraction tool is crucial, as using one that’s too small can result in further breakage, while one that’s too large may not engage properly with the snapped bit.
Drilling Out the Bit
Another common method involves drilling out the snapped tap bit. This is typically done by drilling a hole in the center of the broken tap, using a drill bit that’s slightly larger than the tap. The goal is to create a hole that allows for the removal of the majority of the tap, after which the remaining parts can be removed with pliers or other gripping tools. Care must be taken not to drill too far or too wide, as this can damage the surrounding material.
Advanced Techniques
In some cases, more advanced techniques may be necessary, especially if the snapped tap bit is deep or the material is particularly hard.
Welding a Bolt to the Tap
For especially stubborn cases, a more aggressive approach can be used. This involves welding a bolt to the end of the snapped tap bit. Once the bolt is securely welded, it can be used as a handle to attempt to pull out the tap. This method requires caution, as it involves heat and can potentially damage the surrounding material or start a fire.
Safety Precautions
Regardless of the method chosen, safety should always be a top priority. This includes wearing protective gear like safety glasses and gloves, ensuring the work area is well-ventilated, and following all safety guidelines for the tools and materials being used.
