What is the difference between cordless drills




















Well, not quite. However, torque figures on specification sheets can be confusing depending on how the torque is measured. A great example of this is hard and soft torque. Maybe the best way to describe this is to imagine driving a woodscrew into timber.

As the screw is driven deeper, more and more torque is required, gradually increasing until the head reaches the material — this is referred to as soft torque. Now consider driving a threaded bolt into a pre-tapped steel plate; once the thread is engaged there is very little resistance encountered as the bolt passes freely through the threads.

The torque at that instant increases dramatically, giving a very high reading — this is considered hard torque. The difference is: drills can maintain the torque level throughout the entire turning process. Many people are often surprised to see a powerful drilling machine continue to drive in a large construction screw, when an impact driver with a much higher torque specification, has long given up. The principle of a metal anvil being struck repeatedly by spinning hammers is bound to generate noise — and this is one of the drawbacks of an impact driver.

The noise from the drill comes from the motor and gearbox combined, and although you can hear it, the sound levels are certainly more bearable. Whilst we would always recommend wearing ear protection in any drilling or driving application, drills are certainly quieter than impact drivers.

The exception is when impact or percussion drilling in masonry, with a combi drill. More recently, a handful of power tool manufacturers have launched tools that look just like an impact driver, but much quieter in use. Pulse tools have been around for some time but were only traditionally found in pneumatic machines — often used on assembly lines.

The wave then pushes two paddles around a sealed chamber, a quarter turn each time. The other benefits of Pulse technology are:. The downside is: torque is reduced making these machines ideal for small to medium-sized woodscrews and small self-drilling screws or self-tappers. For these specific applications, tools like the Milwaukee Fuel Surge might just be the perfect screwdriving companion.

Having highlighted the key features and differences between impact drivers vs drills, one could argue that the choice of tool will ultimately be decided by the amount of time the operator spends drilling or driving. However, one application often precedes the other, which could explain why the drill and impact driver partnership is ubiquitous on the jobsite.

Size Front end Working mechanisms Torque delivery Torque Noise Impact Driver vs Drill — Size When I first set about trying to explain the characteristics of each tool, it prompted a sigh and plenty of head-scratching.

Drill Size — mm. Impact Driver Size — mm. What is an impact driver? What is a drill? Instead of a keyless chuck, it has a collet that accepts hex-shank driver bits. This tool is specially engineered to do one job: drive screws, which it does faster and easier than any other tool. The tool uses both bit rotation and concussive blows to power-drive screws through the thickest, densest woods. The result of this two-punch combination is raw, unadulterated power.

For example, the new volt Rockwell RKK2 impact driver has a three-speed brush-less motor that produces up to 1, in. More than enough power to satisfy the most-demanding applications. Yet despite all its brute strength, an impact driver is extremely easy and comfortable to use because the concussive action transfers much of that high-energy torque directly to the screw, not to your wrist or forearm.
