Cobalt is a well-known material used in the manufacturing of drill bits for its durability, heat resistance, and ability to cut through tough materials. But can cobalt drill bits effectively go through an extractor? The answer is yes, but it's important to consider a few factors and use the right technique.
Firstly, let's understand what an extractor is. An extractor is a tool used to remove broken or stripped screws, bolts, or other fasteners from a material. It typically consists of a drill bit with reverse threads and a tapered design, allowing it to grip onto the fastener and unscrew it.
When it comes to using a cobalt drill bit with an extractor, it's essential to select the appropriate size of both tools. The extractor should have a slightly smaller diameter than the cobalt drill bit to ensure a tight fit and maximum gripping power. If the extractor is too small, it may not be able to engage with the fastener properly, resulting in little to no extraction force.
Before using the cobalt drill bit, it's important to create a pilot hole in the center of the broken fastener. This will help guide the drill bit into the correct position and prevent it from wandering off-track. Cobalt drill bits are known for their excellent centering capabilities, making them ideal for this task.
Once the pilot hole is created, you can proceed with drilling using the cobalt drill bit. Cobalt drill bits are specifically designed for drilling through tough materials such as stainless steel, cast iron, and hardened steel. Their high heat resistance prevents the drill bit from dulling or overheating during the drilling process.
When drilling with a cobalt drill bit, it's crucial to use a low rotational speed and plenty of lubrication. The low speed helps maintain control and prevents the drill bit from wandering or breaking. Lubrication can be achieved by using a suitable cutting oil or even water-based lubricants. This helps to reduce friction and heat buildup, extending the life of the cobalt drill bit.
After drilling through the broken fastener, it's time to use the extractor. Insert the extractor into the newly drilled hole, ensuring it's fully engaged with the fastener. Use a wrench or a pair of pliers to apply turning force to the extractor. The reverse threads on the extractor will grip onto the fastener and start unscrewing it from the material. Slow and steady pressure is usually sufficient to remove the broken fastener successfully.
In some cases, the broken fastener may be extremely stubborn or heavily rusted, making extraction more challenging. If the extractor starts to slip or lose its grip, it's crucial to stop immediately and reassess the situation. Applying excessive force can cause the extractor or even the cobalt drill bit to break or become permanently stuck.
To summarize, cobalt drill bits can effectively go through an extractor when used correctly. It's essential to select the appropriate sizes of both tools, create a pilot hole, drill at a low speed with lubrication, and use steady pressure during extraction. By following these steps, you can confidently and effectively remove broken or stripped fasteners using cobalt drill bits and an extractor.
