Types of power drills and their uses

With several power drill types on the market, it’s important to choose the right one for your D.I.Y. projects. Bunnings Tools Buyer Paul outlines the benefits and some project examples for each type of drill in your ultimate power drill guide.

Cordless vs. corded drill drivers

Cordless or corded power drills, also known as drill drivers, are ideal “…for drilling holes and driving screws into most materials except masonry,” describes Paul. The main advantage of using a cordless power drill for your D.I.Y. projects is convenience. You can use a cordless drill anywhere you like whereas a corded drill needs to have access to electricity nearby or an extension cord.

Cordless power drills are available in a range of voltage sizes, for example 12V, 14.4V and 18V. Drills with a higher voltage are more powerful and have a lot of features but are bigger and heavier than those with lower voltages.

Paul notes that “the main advantage of choosing a corded power drill is that they provide you with a higher power at a constant rate. This is ideal for tougher jobs and heavier workloads.

The power of an impact driver

An impact driver works differently to a standard drill by offering you more power through higher bursts of torque. Paul notes they are “ideal for driving screws because the bursts of power provide more force and it’s less likely to strip the heads of the screws.” However, because you never know when the extra power is going to kick in, it can result in less precision.

An impact driver is the perfect power tool if you’re working on a project that requires a lot of screws, such as fastening decking boards or roof sheets and assembling flat pack furniture or cabinetry.

hammer and rotary

Hammer and rotary power drills

Hammer and rotary power drills are both ideal for drilling through tough surfaces like brick, concrete and stone. Hammer drills feature a hammer function that pounds the drill bit as it rotates, helping it to work its way through dense materials. The hammer function can be easily switched off to become a regular drill when needed. “The constant torque at a lower rate of a hammer means you’ll get through masonry in no time,” says Paul.

Rotary power drills are powered by air pressure and provide you with a lot more impact than hammer drills. They’re generally more durable than hammer drills and have three settings; drill mode, hammer drill or just hammer which works like a mini jackhammer.
