Impact Drivers and Impact Wrenches
116 products · Drills, Drivers and Electric Hammers
Impact drivers and impact wrenches are tools that drive and remove screws and bolts by delivering rotary blows: when resistance increases, the hammer mechanism develops a much higher torque than a standard driver. They are used in metalwork, mechanical assembly, building sites and workshops.
What you will find in the collection
- Impact drivers with 1/4" hex drive, light and compact, for screws and bits.
- Impact wrenches with square drive, from 1/2" up to larger sizes, for bolts and nuts.
- Cordless models with brushless motor, also in kits with batteries and charger, or bare tool only.
- Pneumatic models, powered by compressed air, for heavy use.
How to choose
Start with the drive: the 1/4" hex is ideal for screws and fixings, the square drive for bolts and nuts with sockets. Then check the maximum torque, in Nm, suited to the tightening you need, and the battery voltage. If you already have other cordless tools, choose the same system, because batteries are not interchangeable between different brands. For continuous use in a workshop, pneumatic models are a good alternative, if you have a compressor.

Frequently asked questions: Impact Drivers and Impact Wrenches
What is the difference between an impact driver and a standard driver?
A standard driver applies a constant torque. An impact driver delivers rotational blows when the resistance increases, and the resulting torque is much higher, which is useful for loosening rusted bolts and tightening large nuts in fabrication and on site. For small screws and precision work, the standard driver remains more controllable.
Which drive should I choose: 1/4 hex, 1/2 square or 3/8?
The 1/4 inch hex drive, as on the Milwaukee M18 FUEL FID3 1/4 inch hex impact driver, is for light screws and bits. The 1/2 inch square drive, as on the Milwaukee M18 FUEL FHIW2P12 high-torque 1/2 inch square impact driver, is for larger bolts and nuts. The 3/8 square drive is a middle option, suitable for intermediate work.
How do I choose the torque of an impact driver?
Check the maximum torque stated by the manufacturer in the data sheet and compare it with the bolts you need to tighten. For precise tightening, use a model with torque control, such as the M18 FUEL ONE-KEY impact driver with torque control, 1/2 inch square drive. For simple loosening, the maximum torque is the most important figure to check.
Battery or cable for an impact driver on site?
The range is made up mostly of battery models, often sold in kits with batteries and charger, so check what is included. A battery gives freedom of movement on scaffolding and in areas without mains power. For heavy use on site, it is useful to have spare batteries of the same platform as your other tools.
What is the brushless motor in drivers used for?
A brushless motor has no carbon brushes, so it wears less and delivers more for the same battery. On impact driver data sheets you will find the term brushless, which changes durability and the jobs the model is suited to. Check in the data sheet whether the motor is brushless before choosing, because it affects maintenance.
How do I use an impact driver safely at height?
Hold the machine with two hands and set the drive on a stable point, because the reaction of the blow can make the tool slip. If you work at height, use a restraint system in line with site rules. Wear eye protection and gloves. Do not use worn bits or bits of the wrong size, because they can break.
What is an impact wrench used for in fabrication?
An impact wrench is used to tighten and loosen bolts on metal structures and wheels. The free mass produces a rotary blow that breaks loose large or seized nuts. Choose the correct square drive and a bit in good condition, so you do not damage the nut. Secure the workpiece or structure before starting, because the blow can move it.
