• Material: When selecting drill bits for metal, material is the first factor to consider. High-speed steel (HSS), cobalt, and carbide are the most frequent materials. Cobalt and carbide are more costly but offer higher durability and precision than HSS.
• The coating of the drill bit is an additional crucial component to consider. Coatings such as titanium nitride (TiN) and black oxide can increase the bit's longevity, heat resistance, reduce friction, and improve accuracy.
• The size of the drill bit you select will depend on the nature of the project you are undertaking. Choose a drill bit that corresponds to the size of the hole you need to create in the metal.
• Point Angle: The drill bit's point angle determines how easy it can penetrate metal. A smaller point angle (about 135 degrees) is optimal for harder metals, such as stainless steel, whereas a higher point angle (approximately 118 degrees) is optimal for softer metals, such as aluminium.
• The shank of the drill bit is the portion that is placed into the drill. It is essential to select a drill bit with a shank compatible with your drill. Some metal drill bits have a round shank instead of a 1/4-inch hex shank.

Q: Can I use standard drill bits on metal?

A: Although standard drill bits can be utilised on metal, they are not advised for heavy-duty or precise drilling. Metal drill bits are intended to endure the heat and pressure of metal drilling, and they also provide improved precision and accuracy.

Can I use metal drill bits with a drill press?

Yes, a drill press is a great tool for drilling precisely and precisely through metal. Ensure that the drill bit you select is compatible with your drill press.

How can I determine whether I need a cobalt or carbide drill bit?

A. Cobalt and carbide drill bits are optimal for drilling through tough metals such as stainless steel and cast iron. A high-speed steel (HSS) drill bit will sufficient when working with softer metals such as aluminium or brass.

When drilling into metal, it is essential to have the proper drill bit. By examining material, coating, size, point angle, and shank, you may select the optimal drill bit for your project. When working with metal, be sure to select a drill bit that is suitable with your drill or drill press, and always wear adequate safety equipment. With the proper drill bit and skill, it is possible to create precise and accurate holes in metal objects.
