How To Buy Drill Bits

Since drill bits are so vital to the proper execution of just about any job that utilizes a drill, we’ve decided to write this guide on how to properly buy them. That’s because it’s not only important to choose the best drill bits available, but it’s also important to choose the right ones for the material being drilled. Although some handymen seem to think that any bit can be used for any job, that’s simply not true. Choosing the wrong bit for use with the wrong material can really have a negative impact on the outcome of the job.

Drill Bit Materials & Finishes

Anyone who’s been through the tool section of their local hardware or building supply store knows that there are drill bits made out of a variety of different materials and coated with a number of different coatings. Looking at this selection may make a person believe that it’s difficult to select the right one for their needs, but that’s not true at all. Although it certainly looks like there are a lot of different types available, drill bits are usually only made out of a half-dozen or so materials. Below are some of the more common materials and finished used to make drill bits.

  • Cobalt Bits: These bits are used for difficult materials such as stainless steel, but can also be used for aluminum boring. Its tough composition and ability to dissipate heat rapidly makes it an ideal choice for these jobs.
  • HSS or High-Speed Bits: These bits can be used for a variety of different projects, so they’re fairly versatile. They can be used for dripping into aluminum, fiberglass, PVC, and wood.
  • Titanium-Coated HSS Bits: These are more durable than ordinary HSS bits and are suitable for drilling into PVC, fiberglass, some metals, and wood. They tend to stay sharper and produce less friction than ordinary bits.
  • Black-Oxide HSS Bits: These are also more durable than plain high-speed bits, but they aren’t as durable as titanium coated bits. They can be used for some metals, wood, fiberglass, and PVC.
  • Carbide-Tipped Bits: These are designed for drilling into masonry or into tile walls. They stay-sharper and last longer than HSS, black-oxide or titanium-coated bits.

Drill Bit Angles

Most people don’t have to worry too much about drill bit angles. That’s because most bits have either an angle of 118-degrees or 135-degrees. Although professionals may want to be fairly precise when considering their drill bit angles, most DIY enthusiasts don’t have to worry too much about it. However, there’s one thing to keep in mind when considering bit angles: 118-degree bits are suitable for soft materials and 135-degree bits are suitable for harder materials.

Drill Bit Shanks

Although most people don’t think about drill bits when they hear the word shanks, this part of the bit is the part that actually fits into the chuck of the drill. Shanks are available in a large number of varieties, but most people will probably use one of three different types of shanks: Round, Hex or SDS shanks. Let’s examine each one more closely.

  • Round Shanks: These fit perfectly in the center of the chuck, so it’s generally considered to be the most accurate shank available.
  • Hex Shanks: As their name suggests, these shanks have a hexagonal shape. This shape allows the chuck to better grip the bit, and this allows the user to get more torque.
  • SDS Shanks: These type of shanks are designed to be used with hammer drills.

The Three Most Common Types Of Bits

Now we’ll examine some of the drill bits that are available. Although the scope of this article doesn’t allow for an in-depth look at all of the drill bits available, we can take a closer look at 3 of the more commonly used ones.

  • Twist Bits: These are the ones that are most commonly used because of their versatility. They also tend to be the more inexpensive drill bits available.
  • Step Bits: These look like a pair of stairs, which allows the operator to perform a wider variety of jobs. They also tend to resist material clogging, so they’re a good choice for drilling plastic or aluminum.
  • Auger Bits: These have a top that’s designed to bore into wood and they have a fluted design that allows for a cleaner cut.
