While cordless drills and cordless impact drivers both have different purposes, they also have several similarities. In truth, for most tasks you’ll substitute one for the other and get the job done. However, in these situations typically one can work better than the other – it all depends on the job, your skills, and personal preferences.

How they work.

A battery powered drill works using a straight-forward electrical motor. By pulling the trigger switch, the electric motor activates and spins the bit. Current day drills have variable-speed trigger switches; that means that the harder you pull the faster the motor rotates. Some possess switches letting you change the top speed and customize for the current task.

Cordless impact drivers also possess an electric motor which is employed to spin the bits. The electrical motor is not as strong with lesser power, although it usually spins quicker. But an impact driver contains additional mechanisms – a hammer and anvil – that engage when more torque is needed. These components add much extra power to the driver.

The hammers are rotated at a high velocity within the motor. When they are moving quick enough, they contact the anvil. This gives a loud banging sound to the cordless impact driver, together with increased torque. The method also leads to decreased back-torque on the operator’s arm and hand making it simpler to manipulate.

Which driver works the best?

Each tool has different strong points. Not surprisingly, for drilling out holes you’d in all probability choose a drill. Most battery powered drills have finer control at low rpms, allowing you to more precisely begin a hole. Additionally, to use a cordless impact driver for drilling you either need a collection of hex-shafted drill bits or a drill-bit chuck accessory.

An impact driver will be the right tool in specific drilling situations, on the other hand. When making big holes using a spade-bit, for example, the larger power and the inner mechanism will let it drill through with ease without using up the battery as fast as a cordless drill.

If the task is driving screws, a drill using a screwdriver bit can work fine a lot of of the time. For small screws, a drill is what you should use thanks to the fine control – a powered impact driver is so powerful, you’ll over tighten or perhaps tear the screw head right off.

For most screwing jobs, though, the best alternative may be an impact driver. The speedy impact blow means that the power is delivered to the screw so quick that even in tough situations, the bit doesn’t have time to come out of the screw head. Thus, the screw is not damaged, and there’s no need for a lot of downward pressure on the screw. Furthermore, because there is no back torque, you’ll be able to screw very long screws into hard woods easily – possibly one handed, if you need to.

When it involves nuts or bolts, once more the impact driver wins easily. An 18v impact can repeatedly drive in long lags without exhausting the battery, not like a drill that can begin to weaken after just one hard bolt.

The victor.

If you just want to drill tons of holes, or you need a lot of precision, then a battery powered drill is the most effective solution. But if you intend on using the tool primarily as a screw-driver, then a cordless impact driver is absolutely the best.
