How to choose the bit

Start from the diameter of the hole and its shape: through, blind or flat-bottomed. Then check the length against the thickness of the workpiece and the shank, which must be compatible with the chuck of the drill or driver.

Frequently asked questions: Professional Wood Drill Bits
Which bit is used for drilling wood?

For wood, use twist wood bits, suitable for small and medium holes, including in sets. For flat-bottomed holes, use Forstner bits; for deep holes in beams, auger bits. Choose the type according to the depth and shape of the hole you need to make.

Forstner bit: when is it used?

The Forstner bit makes flat-bottomed holes with a clean edge, and is mainly used to house hinges and locks in furniture. It works well on solid wood and panels, with a drill at low speed. The collection includes the set of 3 Forstner wood bits in 40, 45 and 50 mm in a wooden box, and hinge cutters.

Auger bits for beams: how are they used?

Auger bits have a long spiral that removes the chips from the hole, letting you drill beams and structural timber, even to depth. The collection also includes long twist bits for drills. Use a drill at low speed and with adequate power, and withdraw the bit often to clear the chips from the hole.

DeWalt Extreme Tri Flute bits: what are they for?

DeWalt Extreme Tri Flute bits have three cutting edges and a length of 152 mm, and are used for clean, precise holes in wood and panels. They are available from 13 to 32 mm, for example the DT90239-QZ at 13 mm and the DT90245-QZ at 32 mm. The third cutting edge helps centre the hole and clear the chips.

Chrome-vanadium wood bits: who are they for?

DeWalt chrome-vanadium steel wood bits are sold as single pieces in blister packs, such as DT4506-QZ, DT4508-QZ, DT4510-QZ, DT4513-QZ and DT4516-QZ. They are practical for joinery and maintenance when an occasional hole is needed. For frequent holes and different diameters, a set is better.

How do you drill wood without splitting it?

To prevent the wood splintering on the exit side, place a piece of scrap wood underneath and drill until the bit comes through, then finish the hole from the opposite side. Use a sharp bit, steady pressure and a speed suited to the diameter. On panels and plywood this precaution is very useful.

Two-flute or twist bits: which to choose?

Two-flute bits, such as the art. 57 bit in the collection, are suitable for holes in softwood and for basic jobs. Twist wood bits have a spiral that clears the chips and produce a more regular hole. For frequent or deep holes, choose the twist bit; for occasional use the two-flute may be enough.
