What are drill bits?

The best drilling machine is no surety that you can drill clean accurate holes unless accompanied by suitable drill bits. Drill bits are tiny bits of metal pieces in a range of sizes with tips molded for a specific type of drilling.

Materials used to manufacture drill bits

• Low and high Carbon Steel – Low carbon steel is softer and is most suited for softwoods and metal. But drill bits made from them require frequent sharpening. On the brighter side, they are cheap. The high carbon steel is harder and better suited for hardwood, requires less maintenance and is more expensive.
• High-Speed Steel (HSS) – This is the best drill bit material for metal because it is designed to withstand high temperatures without losing its shape or efficiency. These bits are expensive but are durable and worth the money if you are a professional. They are used normally to drill wood, PVC, Fiberglass besides metals like aluminum.
• Cobalt – It is a substance harder than HSS and with an ability to handle high temperatures, cobalt is used to drill into a hard substance like stainless steel. The only drawback with these cobalt drill bits for metal is that they tend to break fast and do not last long.
• Titanium – Like hard carbon steel in nature, titanium has the advantage of lasting much longer and the ability to withstand high temperatures well.
• Solid Carbide – One of the hardest substances used to make drill bits, carbide is predominantly used only with high-quality equipment. Because of its brittle nature, it should not be used with hand drills and drill presses. They are used for drilling holes in the hardest of substances.

Coatings on drill bits

High quality metal drill bits often come with additional coating to increase their longevity and performance.
• Black Oxide: It is an economical solution to most of your drill bit issues. Tips coated with black oxide reduces galling, chip welding, friction thus improving penetration. The coating also protects the tips from corrosion and retains the lubricants used for drilling. It is best suited for all HSS bits used for drilling iron and steel. But it is not suitable for aluminum, magnesium and other non-ferrous materials.
• Titanium nitride: This is an expensive option in comparison but it improves the productivity as it increases the speed of the drill bit when compared to other coated and uncoated bits. The titanium nitride increases the hardness of the bit and creates a thermal barrier thereby improving the lifespan of the tool. This coating is suitable for both ferrous and non-ferrous metals like aluminum and magnesium, etc. The coating is in gold color.
• Titanium Carbide: Blue gray in color this coating is ideal for stainless steel, cast iron, and aluminum materials. The tips stay sharper longer and can be used even in masonry and tile drilling.
• Titanium Aluminum nitride: This coating is violet colored and used for carbon steels. It cannot be used for aluminum materials.

Drill Bit types for metals

Not all drill bit heads for metals have the same points. Each bit is designed with a specific purpose. Here we have listed the various types:
1. Twist Drill Bits: The most commonly used drill bits. They are suited for drilling small holes, are economical and can be used on a wide range of materials.
2. Auger: For large deep holes, you must use auger drill bits as they have extra flutes that remove the chips from the hole. These drill bits can’t be used with power drills.
3. Hole Saw: These tips literally saw through the wood to make provision for hardware installation for doors and windows. The holes are wide and appear cylindrical in shape.
4. Spur point: For clean precise holes, use these drill bits which come with two raised spurs to maintain the accuracy during drilling.

What does a metal drill bit look like?

Different drill bits are meant for different purposes and materials and hence they appear different too. If you wish to choose a drill bit for metal look out for the following features:

  • Color of tip: usually they are black, blue or gold depending on the coating
  • Angle of the tip: The flutes of the drill bit taper between 118 degrees and 135 degrees
  • Diameter: It ranges between 1/16th inch to ½ inch.
