Our Best Drill Bits Reviews – Quality Tools For Your Next Project

When it comes down to quality workmanship, you need quality tools to do the job right. Drill bits come in various shapes, sizes and are made out of a wide array of materials. Some bits have a coating on the tips that allow for the bit to stay sharper over time and also reduce friction when drilled at high speeds.

So, how do you know which drill bit is right for your job? The truth is that most people don’t know and they end up using the wrong size or the wrong type for the material they are drilling into. In this guide, I will give you all the necessary info you need to make sure that your next job is a success by using the correct drill bit.

Drill Bit Materials

There are 3 main types of materials that drill bits are made out of and each one has a specific purpose for the type of material you will be drilling into.

  • HSS (High Speed Steel): One of the most popular types and is good for soft steel, wood and plastics.
  • HSCO (Cobalt): This type of drill bit is a HSS bit with approximately 5-8% of cobalt added to the base material. If you are planning on drilling into hardened steel, this is the bit for you.
  • CARB (Carbide): If you need a drill bit that can drill into the hardest materials, then this is the one for you. Carbide drill bits are made for production drilling and should only be used under close supervision. Do not use these types of bits in hand drills or drill presses.

Drill Point Angles

118 degree drill bit angleThe most common drill bit angle is the 118 degree angle which has two cutting lips at the tip.

The 118 is generally used for drilling into soft material like wood, plastic and soft metal. You can use it to drill through steel, but this will cause it to dull quicker.

 

135 degree drill bit angleThe next most common drill bit angle is the 135 degree angle, typically called the self-centering angle.

This has four cutting lips that cause the bit to drill faster usually good for stainless steel and hard metal.

Choosing The Right Drill Bit Size

Most drill bit sets come with a pilot hole chart to help you figure out which size you need. One thing to keep in mind is that the charts are designed by measuring the size of the screw shank. The charts are not exact science and are really to be used as a guide. Here are a few guidelines to get you started:

  1. If you are drilling into soft wood, you will need to choose a drill bit that is 1/64 smaller than the intended target hole size.
  2. If you are drilling into hard and dense substances, you will need to choose a bit that is exactly the same size as the target hole size.

Choosing The Right Drill Bit Type

The type of drill bit that you will need is determined by the type of material that you will be drilling into.

Here are the most common types of drill bit types:

  1. Wood Drill Bits: These types of bits have small and narrow tip with small spurs on either side that allow the bit to carve away at the wood without splintering it. Most of the wood bits are stainless steel and are good for soft wood. If you are drilling into hardwood, you will want to purchase titanium coated drill bits which will last longer and stay sharper.
  2. Metal Drill Bits: These types of bits have an angled and wide tip and are commonly painted black. These very versatile bits can be purchased with HSS (High Speed Steel) and the more expensive types can have cobalt and titanium coating to help keep them sharp and reduce dulling.
  3. Masonry Drill Bits: If you need to drill through concrete or brick, you will need a bit with gentle sloping on the end. Because drilling into cinder blocks and stone will dull a bit easily, you can purchase highly durable carbide tipped drill bits that can help prolong its life.
