These are designed for clearing short holes through timber quickly. Available mostly in larger diameters, they are used for running holes through framing for plumbing and electrical cables. Both bits have a sharp positioning and starter tips with the larger cutting section behind. Spade bit

However, there are many types of drill bits available, and it can be tricky to work out which one you need for your project.

Designed specifically for use with impact drivers, these are designed to withstand percussive force emitting from the drivers.

If you only need to drill about 30mm into a material, then use a bit that has extra fluted length. It is good practice to drill holes a little deeper than needed, especially in masonry. In these situations, drill swarf can fill the hole and reduce its depth.

Choosing the right drill bit plays a huge role in making your drilling project is a success. It can help you use your power drill efficiently and safely.

There may be times where you have to drill through multiple layers of materials. For example when wall framing, you may have to drill through tile and compressed cement sheets. We recommend using a multi-material or construction bit. These are designed for drilling through a range of tile, masonry, timber and metal materials.

We recommend using a specialised diamond core bit or glass and tile spade bit for these. These bits must be kept wet while drilling. You can also use a fresh and sharp standard masonry bit. Keep area wet while drilling with diamond bits

Ideally, the length of the drill bit should be measured against the length of its fluted section, not including the straight shank section at its base. This helps to avoid the risk of your chuck spinning against and damaging the face side of the material.

These come in a variety of forms. The basic ones are mainly used to drill wide holes for screws that sit flush with the surface. Others have an integrated pilot drill so that you can both pre-drill and counter sink.

These are used when a long hole is needed to be drilled through timber. For example, when you may need to run cables, pipes or cyclone rods through framing, floorboards and bearers or joists.

In situations where you need to drill through your material, the bit should be at least 10mm to 20mm longer than the material thickness. This allows for the bit to cut a clear hole out the other side.

This hole is the correct size for your fastener to snuggly pass through. For example, if you are using M12 bolts, you ideally want a hole slightly larger than the M12 (12mm) bolt to avoid having to hammer it through. A 12.5mm or 13mm bit is ideal.

These bits have a sharp position tip and raised cutting spurs on the outside edge of the flutes. They are designed for clean cutting when making furniture, or other similar projects.

These bits look more like a router bit than a drill bit. They are designed for creating holes with flat bottoms. For example, when fitting dowels in furniture or concealed hinges in cabinetry.

It is also important to know the hole diameter you require for your project. This determines the type and size of bit you will need.

These bits have tiered cutting stages. They are designed for cutting accurately sized holes through materials such as thin sheet metal, plastic, aluminium and fibreglass.

A masonry bit should be used for these materials. In most cases, we recommend using a hammer drill on hammer setting to aid the drilling process. Note that if drilling tiles, hammer setting might crack them. For very dense igneous rocks like granite or basalt, you may need to use specialised drill bits.
