Frequently Asked Questions (FAQs)

1. What is a twist drill bit used for?

Twist drill bits are primarily used for drilling through metal, but they can also be used for drilling through wood and plastic. However, they are not suitable for drilling into masonry or concrete.

2. What are the different types of twist drill bits?

There are several types of twist drill bits available for automated machinery, including carbon steel, high-speed steel, carbide-tipped, and solid carbide. These bits may also come with different coatings, such as black oxide, bronze oxide, a combination of black and bronze oxide, and TiN coatings.

3. What are the disadvantages of twist drill bits?

Twist drill bits have a few disadvantages. They can only create round holes, which may not be suitable for all applications. Additionally, when drilling certain materials like ceramics or glass, twist drill bits can cause chipping or cracking if not used properly.

4. What is the difference between a twist drill and a core drill?

Twist drills often require pre-drilling to locate the center and progressively reach the desired diameter. On the other hand, core drills do not require pre-drilling as the ejector pin locates the center, allowing you to cut the finished size hole in one go. Core drills also have more effective cooling.

5. What is the strongest drill bit?

Carbide drill bits are considered the strongest drill bit material and can cut through hardened steel. If carbide bits are not available, titanium and cobalt drill bits can also be used for drilling hard metals, although they may take longer to drill compared to carbide.

6. Is it necessary to spot drill before drilling a hole with a twist drill?

For screw machine-length twist drills, spot drilling is not necessary as they are shorter and more rigid. However, there may be instances where a jobber length drill is required for deeper holes that cannot be accommodated by screw machine drills.

7. Which is better cobalt or carbide?

Carbide drill bits are typically harder than cobalt drill bits, making them suitable for drilling stainless steel and other hard metals. Carbide bits also retain their sharpness for a longer period compared to cobalt bits.

8. What are the hardest wearing drill bits?

Carbide drill bits are considered the strongest drill bit material and can cut through hardened steel. If carbide bits are not available, titanium and cobalt drill bits can also be used. However, drilling with titanium or cobalt bits may take longer compared to carbide bits.

9. What is the best practice when drilling with a twist drill?

When drilling through holes, it is important to reduce the pressure as the bit approaches the other side of the material, especially with hand drills. This helps prevent the drill from tilting suddenly and getting caught, reducing the risk of injury.

10. What is the advantage of a twist drill over a flat drill?

Twist drills have several advantages over flat drills. They consume less power for the same size and depth of hole, have a longer cutting edge life, provide easy passage for chips to escape from the hole, and reduce operation time by allowing for high speed and feed with required safety.
