FAQs
How do I choose the right drill bit for my project?
Choosing the most suitable type of drill bit is essential for drilling clean holes.
The key things to consider when looking for a drill bit include the material you need to drill, the drill bit type, hole size and specialist coatings designed to enhance performance.
What are the benefits of a diamond porcelain drill bit?
Diamond porcelain drill bits are ideal for use on hard materials like ceramics, glass and porcelain tiles. The diamond coating makes them extremely durable and long-lasting, reducing how quickly they wear down when used with tough materials.
They come in various sizes and are also highly accurate, providing clean and precise cuts while reducing the risk of structural damage or chips.
What materials can drill bits be made of?
Drill bits can be made from various materials for different purposes. For example, diamond-tipped bits are ideal for drilling brittle materials such as glass and tiles, while a tungsten carbide-tipped bit is best for masonry.
High-speed steel (HSS) metal drill bits are great for drilling wood, metal and plastics.
Can drill bits be sharpened?
Most drill bits can be sharpened using a drill bit sharpener or a bench grinder. Sharpening extends the life of the drill bit and maintains its cutting efficiency.
Replace drill bits when they become dull, chipped, or damaged.
What should I consider when choosing the correct drill bit diameter?
Choosing the right diameter depends on the size of the hole you want to create. A small hole may require a 3-5 mm bit, while a larger hole could need something 10mm or above. Always check the material and your tool's chuck size or shank compatibility before selecting.
Are masonry drill bits suitable for drilling into concrete and brick?
Yes, a masonry drill bit is suitable for concrete, brick, and stone.
For especially hard materials, look for bits with carbide tips to resist wear and maintain clean cuts. If you're working on a heavier block wall or dense stone, core drill bits may be more appropriate for the task.
What kind of bit should I use for brittle materials like tiles?
When drilling into brittle surfaces such as tiles, use a bit specifically designed for hard materials. Diamond-tipped or tungsten carbide bits help reduce chipping around the edges and give smoother results.
To ensure clean cuts, avoid applying too much heat or pressure and let the bit do the work.
Can I use HSS drill bits with impact drivers or combi drills?
HSS drill bits are typically used with standard power drills, but some are reinforced to work with combi drills or impact drivers.
Be sure to choose bits that are suitable for the task and check the product rating to ensure they can withstand the high speed and torque of impact tools.
What’s the difference between auger bits and other bits for wood?
Auger bits are designed for drilling deep, clean holes in wood, with a spiral shape that helps lift debris as you go. They’re ideal for large-scale woodworking or when precision is needed over longer lengths. Other types like Brad point or Forstner bits are better for clean cuts in softer materials or shallow applications.
