Drill holes in wood - the most important tips

A hole in wood should "sit" correctly with the first attempt, without the material splintering or the drill possibly getting stuck. This does not always succeed, because when drilling in wood can make some mistakes. Read here how to specifically avoid such problems and create clean drill holes that provide a proper base for bolting.

Which drill is the right one?

Of course you use a wood drill for drilling in wood, but which format should he have? Take a drill with a center point at hand; For small and medium sized holes a twist drill is the tool of choice.

Flat, wide drill holes of up to 3 cm depth are best drilled with a Forstner drill, deep holes from 8 cm to do preferably with a snake drill. Use the drill or cordless screwdriver for drilling.

So you drill in wood

If possible, drill along the length of the wood grain, then the result is best. Here's how to do it:

  • Secure the workpiece sufficiently against slipping, for example with clamps.
  • If you are drilling on a countertop, put an old wooden plate underneath to avoid damaging it. Thus, when drilling through no fiber tears.
  • Work at medium speed for a clean bore without burn marks due to excessive friction.
  • If you would like to make a screw connection between two wood elements, then drill the part that is to be screwed first about half a millimeter larger than the screw diameter. The second part is then drilled about a millimeter tighter.
  • For the screwing special wood screws are recommended, whose shank is either cylindrical or conical shaped. The striking tip facilitates screwing in wood, as well as the steep slope.
  • Generally speaking: with Torx screws your screwdriver will find the best grip, even with Phillips screws it works well. Slotted screws are less recommended because it slips off easier.
  • When using countersunk screws, make sure that the drill hole depth is sufficient to allow the screw head to be sunk.

Tips & Tricks

When drilling through wood, avoid splitting the fibers by pulling out the drill bit at the first small opening and fitting on the opposite side.
