This year, I've finally gotten comfortable using my power drill. Honestly, it's really empowering once you know what you're doing. I highly recommend information technology.

When, similar me, you're a beginner in the power drill universe, there are a lot of pieces to navigate (at least, compared to a hammer and nail!). At that place's the drill, the bombardment, the screws, the anchors, and the drill bits. It can seem a chip overwhelming at the start.

One thing that left me scratching my head: If you're doing a project that requires pre-drilling (such as hanging shelves), how do y'all know what size drill fleck to use for your airplane pilot hole?

Thankfully, a pro stepped in to help guide me. Eli Donahue, a carpenter at Stand up and Build in New York, showed me how unproblematic it is to determine which drill chip to utilise for your project.

Let's say y'all accept your shelves ready to hang, the appropriate screws, and you're drilling into a stud, so no anchors are needed. If you know the size of the screw, you can locate the size of the drill fleck by looking at the opposite end from the abrupt point of the fleck. Information technology's likely engraved there.

Simply if y'all don't know the size of your screw, how practice you know which drill bit to utilize? 1/8? 1/sixteen? 5/32? Donahue has an piece of cake manner.

How to Decide What Drill Bit to Use

Here's what the pro says: You can really but eyeball it (carefully).

Donahue says you only concord the drill bit upwards directly in front of the screw. "There's the central column of the screw, then there are the teeth of the screw," Donahue says. "You desire to choice a drill bit that's the size of the key column, not the screw."

So when you're holding your drill bit in front of the spiral, if yous can meet the fundamental column likewise as the teeth, the chip is likely as well small, and so endeavour a size up.

If you can't see the teeth or spirals of the screw when you agree the drill bit in front of information technology, the bit is likewise large, so size down.

If you're holding the drill bit in front of the spiral and you lot can encounter the spiral, but not the fundamental column, congratulations! Yous have the correct drill fleck size for this screw.

Note that if you're not drilling straight into a stud, you'll probable need to apply an anchor for your projection.

How to Make up one's mind the Size of Your Drill Bit for an Ballast

Donahue says the same method applies here.

If you lot're using an anchor, he says to hold the drill bit up to make sure information technology's the same size as the anchor minus the flange (the part at the end of the screw that sticks out from the wall).

"You want a drill bit that'due south big plenty to drill a hole in the wall, and easy to push the anchor in with your thumb," Donahue explains. "You lot don't want to accept to strength it in there. The drill flake should be the same size as the body of the anchor you're using."

What to Do if You Pre-Drill a Hole That's Too Small-scale

"Simply step information technology upwardly a size," says Donahue. Cull the side by side bigger bit, then re-drill in the same spot. He says drilling a hole that's too small is definitely the easier problem to fix, as opposed to fixing a hole that's too big.

What to Do if Yous Pre-Drill a Hole That'southward Also Big

"If it'due south as well big, and so you accept to buy a piffling spackling, seal it up, and go somewhere new," Donahue says. In other words: Err on the side of too small.

While there are other options for fixing too-big holes if yous're a more advanced carpenter, he advises the easiest matter to practise is to let it go, fill the too-large hole and motility on. And don't be also hard on yourself.

"Spackling is not that expensive!" says Donahue. You can choice some up from your local hardware store or on Amazon for less than $6.

How Many Drill Bits You lot Need as a Beginner

"For near things, you're not going to need too many drill bits because you're not going to need that much precision," Donahue explains. "If you're 1/16 inch too big or modest, it'southward unremarkably not going to exist too large of a deal if you lot're hanging a shelf."

In other words, save your money on the 230-piece drill bit set if you're but doing some basic around-the-business firm DIYs.

So have a deep breath, hold up your drill fleck in forepart of your spiral or anchor to decide the size needed, and go started on your next projection with the conviction of a pro.
