Drill Bits

Drill bits are used with drills and are cutting tools designed to cut holes of various sizes in many different materials, such as wood, steel, tiling, plasterboard, brick and concrete. Drill bits are used widely in the construction and woodworking sectors, as well as by many DIYers for jobs around the home.

Frequently Asked Questions about Drill Bits

How do I avoid my drill bit slipping during use?

To prevent slipping, ensure the drill chuck is tightly secured, use a centre punch to mark the drilling spot, and choose bits with a non-slip shank design, such as a hex shank.

Can drill bits be sharpened, and how often should I do it?

Yes, some drill bits can be sharpened using a bench grinder or specialised drill bit sharpener. Sharpen them whenever you notice reduced cutting performance or excessive heat generation during use.

How do I ensure a long lifespan for my drill bits?

To extend the lifespan of your drill bits, use the correct type for the material, apply cutting oil for metal drilling, avoid excessive pressure and keep the bits sharp and clean after use.

What are the benefits of step drill bits?

Step drill bits allow you to drill multiple hole sizes with one bit, making them perfect for working with thin materials like sheet metal. They eliminate the need for frequent bit changes, saving time and effort.

When should I use a core drill bit?

Core drill bits are used for creating large-diameter holes, often in concrete, brick or masonry. They are ideal for plumbing, electrical installations and other construction tasks requiring precision and depth.

What are spot weld drill bits used for?

Spot weld drill bits are designed to remove spot welds without damaging the underlying material, commonly used in automotive repair and sheet metal fabrication.

Can I use drill bits for wood on metal surfaces?

No, drill bits for wood are not suitable for metal. They may dull quickly or break. Always use metal-specific bits, such as high-speed steel (HSS), for drilling into metal.

How should I store screwdriver bits to keep them organised?

Use a dedicated bit case or magnetic holder to keep bits sorted by type and size. Proper storage helps prevent loss and makes it easier to find the right bit quickly.
