Drill Bits

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.

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.

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.

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.

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.

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

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.

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.
