How to Prevent Your Drill Bits From Slipping

When using a power drill, you'll need to ensure that the bit is secured to the chuck. The chuck is the sleeve-like part at the end of a power drill. You can open the chuck, after which you can place a chuck inside of it. Even after tightening the chuck, though, the bit may not stay in place. Bits can slip. You can prevent them from slipping, however, by following these tips.

Tighten the Chuck All the Way 

A loose chuck can cause drill bits to slip. If your drill has an adjustable chuck, make sure it's completely tightened. Some chucks can only be opened and closed, but others can be adjusted. You may need to key to adjust the chuck. Regardless, tightening the chuck all the way will help to secure the bit so that it doesn't slip.

Use a Bigger Bit

The size of the bit can affect its risk of slipping. Small bits are more likely to slip than large bits. A thick bit with a wide diameter, for instance, will take up more space inside of the chuck. And by consuming more space, it should fit tighter. If you notice that your bit is constantly slipping, replacing it with a bigger bit may offer a solution.

Avoid Pressing Too Hard

You should avoid pressing too hard when using your drill. Whether you're drilling into wood, metal, polymer or any other material, you'll typically have to apply some pressure. Pressure is what forces the bit into the material so that it will drill a hole. Applying too much pressure, however, may cause the bit to slip.

Clean the Chuck

Sometimes all it takes to prevent a bit from slipping is to clean the chuck. The chuck will accumulate dirt and debris. After all, it's located directly in front of the surfaces into which you drill. As you drill into a surface, some of the dislodged material will be projected toward the chuck. Over time, this dirt and debris can create a loose chuck. The chuck won't be able to hold the bit in place. By cleaning the chuck, you can eliminate dirt and debris.

Inspect the Bit

If a bit is constantly slipping, you should take a moment to inspect it. Maybe the bit is covered in oil, or perhaps it's bent. You can clean a dirty bit to remove oil or other substances. Bent or otherwise physically damaged bits, though, should be replaced.
