If you use tools you understand the importance of choosing the right tool for the job. This is as important with drill bits as it is with any other tool. Let’s have a look at a variety of drill bits and what jobs they do best.

Tapered countersinks

When you’re pre-drilling for screws, tapered countersinks are the way to go. The tapered bit creates just the right hole for the screw’s threads and screw’s shank, in one pass. The countersink creates the required recess for the screw’s head. Add a stop collar and you’ll have perfect control of depth.


It’s common to use cordless tools to drive screws and put nuts on bolts. You need high quality drivers for this or they won’t be able to withstand the torque exerted by the drill, especially when you’re using an impact driver.

Brad point bits

Brad point bits are a must-have for woodworking projects. With their distinct center point and cutting spurs you’ll get very clean holes, and it’s easy to locate the bit on a precise center point.

Boring bits

When you need to make a lot of holes fast, grab a boring bit. With their self-feeding tip they’ll punch through wood crazy fast. These bits are a great choice for construction projects where you’re drilling for plumbing and wiring.

Step drill

When you need to create holes in thin metal give a step drill a try. Need a small diameter hole? Stop at the first step. Large diameter hole? Walk it up to the largest step.

Forstner bits

Forstner bits work great for large diameter holes you need in your woodworking projects. They also allow you to drill overlapping holes, perfect for creating mortises on your drill press.

Twist bits

When you’re punching holes in thick metal, grab your twist bits. You’ll get the widest selection of bits by choosing a set that has fractional sizes, plus lettered and numbered bits.

One Response to “Choosing The Right Drill Bit”

  1. Mark Evans

    why would anyone use an impact driver on a wood drawer? Especially after pre-drilling? The chances or over driving the screw is way too much. Also, the hole seemed so much deeper than the screw. Is there a rule for depth of hole drilled vs. length of screw?
