A Basic Drill Bit Buying Guide

When most people begin a project they think about the materials and the tools they may need to get the job done. Although people often consider the type of drill they may want to use for a job, they too often give little thought to the drill bits they’re going to use for their project. They simply grab whatever bits are around and throw them in their tool bag. Unfortunately, that’s a mistake.

If you want to get the best performance out of your drill and what to ensure that the job you’re doing is done correctly, then you are going to want to give a little bit of thought to the drill bits that you’re going to use. To help you out, we’ve included some of the basics that people need to know about this tool accessory.

One of the first things a person is going to consider when choosing a drill bit for a particular job is the angle of the bit. Although the tool owner can determine for themselves which angle is right for the job they’re doing, there are some guidelines to consider. Below are some of the more common drill bit chisel angles and their uses:

  • 118-Degree Angles: Drilling Softer Materials
  • 135-Degree Angles: Drilling Tougher Materials

Common Drill Bit Sizes

If a particular project doesn’t call for a specific bit size, then the DIY’er may wonder which bit size to use for a job. For most applications around the home, 1/16-inch to 1/4-inch is a suitable size. However, every tool kit, even amateur kits should have a few larger size bits as well. Adding 1/2-inch, 5/16-inch, 3/8-inch, and 7/16-inch can greatly increase the number of jobs they tool operator can use.

The Drill Bit Chuck

Another thing to consider is the chuck of the bit. This is the other end of the bit that attaches to the drill. Most home projects require a drill bit chuck of 3/8-inch, but larger drill may use up to a 1/2-inch chuck. If the bit is going to be used in a drill press, then most presses use a size of about 1/2-inch or 5/8-inch, which is slightly larger than a standard chuck. Although this may seem a bit confusing, the most important thing to remember is that the bit chuck can’t exceed the bit chuck size of the drill or it won’t fit.
