How to Change the Drill Bit

When it comes to drilling holes in various materials, you’ll want to use the right drill bit for the job. In this article, we’ll teach you how to change the drill bit on your lathe so that you can get the hole size and shape that you need.

The Basics of Drilling

The basics of drilling are to use the right bit, using the right speed and depth, and to keep your drill moving. Here are some tips to help you get started:

1. Use the right bit- You need to use a bit that is designed for the material you’re drilling. If you’re drilling into wood, for example, you should use a wood bit. If you’re drilling into metal, you should use a metal bit.

2. Use the right speed- The speed at which you drill depends on the material that you’re drilling through. For example, if you’re drilling into concrete, you should use a slower speed to avoid damaging the concrete.

3. Keep your drill moving- If your drill stops moving, it will become difficult to insert the bit and remove it later. Always keep your drill moving by using a rotating spindle or chuck.

Changing the Drill Bit

If you’re struggling to remove a stubborn drill bit from your drill, it might be time to change the bit. Here’s how:

1. Remove the drill from the chuck by unscrewing the handle.

2. If the bit is sticking, use a small screwdriver to loosen it before trying to remove it.

3. Pry off the old bit with a flathead screwdriver.

4. Insert the new bit into the chuck and tighten the screw until it’s snug.

5. Reattach the handle and screw it in place.

Checking the Drilling Progress

Once the hole is drilled, you will want to check the drilling progress. This can be done by using a micrometer or vernier caliper to measure the depth of the hole. Additionally, you can also use a drill bit gauge to measure the size of the hole. If the hole is too deep or too small, then you will need to adjust the drill bit.


If you’re having trouble changing the drill bit on your drill, there are a few things you can do to try and remedy the situation. First, make sure that the bit is properly seated in the chuck of the drill. If it isn’t, you’ll need to use a wrench or pliers to twist it until it is. Next, check to see if the bit has broken off at one of its corners – this is usually where the problem lies. If it’s broken off, you’ll need to remove it using a Phillips head screwdriver. Finally, make sure that all of the dirt and debris has been cleared away from around the bit before trying to change it – otherwise you might end up breaking something else in addition to your drill bit!
