Factors to Consider When Buying Drill Bits for Metal and Steel 

Choosing drill bits optimized for your specific application is essential; otherwise, you’re likely to be forced to replace the tools and bits too often. First, drill bits are organized according to the job to be done, the medium to be worked on, and the material. That explains why you will find drill bits labeled for use on metal, masonry, and wood. Once you identify your medium and material, then you select the bit size that fits your specific drilling needs.

If you want the best result, several factors are to be considered for the best drill bits for metal.

Drill Bit Material

When choosing a drill bit, one of the important things to consider is the material used in its manufacture. The different metals used in manufacturing drill bits are:

  • High-carbon steel
  • Low-carbon steel
  • High-speed steel
  • Cobalt
  • Carbide
  • Diamond

When buying metal drill bits, it’s best to ‘look for a label that carries the tag HSS (high-speed steel). HSS bits are strong and highly versatile. The more expensive metal drill bits may contain cobalt or have a titanium coating. Steel bits can drill through soft metals such as aluminum and copper, while you may need high-speed steel bits for other types of metals such as stainless steel or cast iron.

Length and Size of the Drill Bit

The drill bit length and size you choose will be dependent on the size of your drilling project. However, you should ensure that the drill you select has a similar size to the type of hole you intend to make. The drill bit size should also match the structure thickness of a particular project.

Compatibility with Your Drill

The type of drill to use for your drilling project is another essential consideration to make. Try and choose a drill bit that will perfectly match the drill type you have or intend to use. The compatibility will contribute to the easy and smooth execution of your drilling project. Besides, it also helps ensure that your drill doesn’t get damaged by the use of discordant drill bits.

Drill Bit Edge or Angle 

Besides the material and coating used in making the drill bit, the edge or angle of the bit point also affects how effectively it penetrates materials or surfaces. Typically, flatter points are used for drilling harder materials, while you can use steeper points for softer materials.

For precise applications, however, you may want to use drill bits that have split points. This design prevents the drill bit from moving or walking into another point/area even when you don’t apply too much force to hold the drill down.

The Pricing

In choosing the best drill bits, a key consideration by most buyers is the product pricing. Most people will, understandably, want to choose drill bits that fall within their budget. That, however, doesn’t mean you should go for cheap drill bits.

Your price considerations should be guided by other important factors such as material, design, size, shape, and your project. Choosing the wrong drill bit will not only delay your project but also put you at risk of getting injured!

Finally, remember that choosing the best drill bit for metal takes practice, and it shouldn’t intimidate you. Carefully refer to the available pilot hole charts before making your final selection. Once you make the purchase, always keep the drill bits organized in their respective compartments in the storage case.
