The Best Countersink Drill Bit Sets Buying Guide

Selecting a good-quality and helpful drill bit set can be tedious if you don’t know the factors to consider and ignore properly.

It becomes even more challenging if you are a beginner and have the slightest knowledge of how a drill bit set works. So, we will cover the A to Z of purchasing factors for the countersink drill bit sets.

Working Materials

The first consideration while buying the drill bit sets isn’t focusing on the drilling tool, but it actually depends on you. First, you need to prominently determine which type of materials you will mostly be working on with the drill bit set.

For instance, a countersink drill bit set is ideal for working with wood boards, but you can’t use it for drilling metal or plastics. For metal, you will need a harder drilling set.

Drill Bit Manufacturing Material and Coatings

The next one you need to consider is the manufacturing material of the drill set, for it assures durability and accuracy in the drilling projects. Drill bits are widely made of various types of steel. The most common steel types are:

  • Low-carbon steel: These are inexpensive and softer. You can use it to drill on thin plastic and wood. But the edge sharpness loses quickly.
  • High-carbon steel: These bits have superior hardness and wear resistance. So, it is perfect for boring holes in metals and hardwood. However, it gets heated quickly, which softens the edges frequently.
  • Cobalt-steel: The cobalt steel-made drill bits are prepared to work at high temperatures. So, professionals use it to bore holes in hard metals, which are expensive, too.

Apart from the manufacturing material, the coating is also crucial. You will mostly see black oxide and titanium-nitrate sheets on the drill bit sets. However, some expensive models have aircraft-grade diamond powder coating that is impossible to wear off.

Shapes and Angles of The Drill Bit Tip

Regular homeowners and DIYers will choose straight shanks for every day drilling chores. On the contrary, professionals and contractors use tapered shanks for heavy-duty drilling tasks. Nonetheless, these days, people also choose hex-shaped shanks.

You must also select the number of pointed tips on the drill bit set. Usually, you will find three-, five-, or six-pointed tips that all prevent vibration and slippage. The sharp angle is also essential to create the drilling holes with proper smoothness.

Available Sizes

The available sizes of the consigned pieces for the drill bits set are also crucial. Ideally, most drill bit sets come with three to five parts with standard sizes.

Some manufacturers might provide six or seven drilling pieces in the package. Make sure you get the standard sizes with the package.
