Drill bits in general and drill bits for metal, in particular, come in a variety of styles. Besides this, you have to consider the size of the shaft and its compatibility with the tool you own. That’s why there are a few things you should learn before buying.

Types of Drill Bits for Metal

  • High-Speed Steel (HSS) drill bits: Are designed to withstand higher speeds without overheating and are ideal for drilling through softer materials that support high speeds. These bits are often used for wood and plastic drilling, but soft metals such as aluminum can also benefit from this type of drill bit.
  • Oxide-coated HSS drill bits: Are similar to the HSS bits above but they are coated with a corrosion-resistant material which increases their resistance and lifespan. They last longer than the HSS but are more expensive. The drilling characteristics are similar.
  • Titanium-coated HSS drill bits: Are more robust and more durable than the two types above and stay sharp for longer. These bits are also suitable for drilling through soft metals, but the investment is well worth the money.
  • Cobalt drill bits: Are designed for tougher materials due to their construction which dissipates heat quickly. This particular makes the bits suitable to use at lower speeds while the resistance of the material makes them suitable to use for drilling hard metals such as stainless steel.
  • Carbide drill bits: Are the toughest on the market, often employed for drilling through masonry. Due to their resistance and durability, these drill bits are also suitable to use on most metals, including stainless steel.

How to Choose the Drill Bits for Metal

1. Construction

Not all drill bits for metals were created equal. Besides the material, you must also consider the construction of the drill bit and above all its tip. Metals can be divided into soft and hard metals, and manufacturers construct different types of drill bits for the various kinds of metals.

Flat point drill bits are suitable for hard metals like stainless steel. Those with steeper points are ideal for softer metals such as aluminum.

2. Size

The size of a drill bit refers to the diameter of the body and typically varies from 1/16 to ¼ inches. However, this is not necessarily a rule, and the actual size of the drill bits goes up to ½ inches depending on the requirements of the project.

3. Shank

One of the most important things to consider is the size of the shank which determines the bit’s compatibility with the chuck of the tool. Most cordless drills have adjustable chucks but impact drivers, for example, are only compatible with a standard ¼ inches hex shank.

Most drill bits for metal have a round or hex shanks with a size between 3/8 and 5/8 inches. The round shanks are ideal for beginners, allowing you to center the drill bit accurately. However, the hex shanks allow for a better tool grip which secures them for higher torque applications.

A few tools, such as the hammer drills, accept slotted drive system shanks which don’t require tightening.
