The drill maintains constant turning torque using gears.

This video clip, from the premium professional brand Festool, illustrates the mechanism very well. This is perfect for applications which require high torque without resistance being passed back to the operator. This powerful action causes rotating hammers to strike an anvil many times a second.

Impact drivers deliver bursts of torque by releasing energy from a spring. The first thing he did was to open the cases of both tools, so I could see the different parts of each machine.īoth machines have a battery-powered motor driving two completely different torque delivery systems. With over 35 years of experience, Simon has seen the insides of literally thousands of power tools, and I hoped he would provide me with a simple explanation. Unsure of how best to describe this, I headed to our service centre and sought the expertise of Simon Wilde, who heads up our team of factory-trained fitters. The working mechanisms of each machine are where the two tools are very different. Impact Driver vs Drill – Working mechanisms The entire range of accessories available for use with a drill chuck is far too numerous to list here – but if the accessory has a shank with any of the aforementioned shapes, the chuck can undoubtedly grip them. The opening and closing action of the chuck makes it possible to grip varying diameters of cylindrical shanks found on drill bits, triangular shanks on many arbours and hexagonal shanks for paddle stirrers, bit holders and screwdriver bits. The self-centring nature of the 3 jaws is to hold bits tightly, and dead-centre of the chuck for precision drilling. A three-jaw chuck is used to hold round, hexagonal, and even triangular-shaped shanks. The drill uses a three-jaw chuck to hold the power tool accessory.
Some brands do make power tool accessories with a ¼” hex shank, specifically for an impact driver. The tool retention system of the impact driver does allow fast and effortless bit changes but can only hold accessories featuring a ¼” hexagon – which can be limiting. The most obvious difference between the two power tools is the physical size – I’m primarily referring to the length of the machine from the tool retaining end to the back of the casing. Despite the machines looking similar, they are in fact quite different. When I first tried to explain each tool’s characteristics, it prompted a sigh and plenty of head-scratching. Over the last year, we have sold 32% more combi drills than impact drivers, which indicates the versatility of the combi drill.īut what is the difference between an impact driver and a drill? In this piece, we break down everything you need to know about impact drivers vs drills, and explore the different uses, along with their advantages and disadvantages, including: There will definitely be a time when having both machines available will make completing a particular task, faster, safer or easier.’ ’ Des Duddy, Joint Managing Director ‘ It doesn’t matter whether you work predominantly on site or in the workshop. This duo of ‘drill and driver’ often constitutes the foundation of most cordless tool kits, as a huge range of power tool accessories can be used with these two machines alone. The most popular cordless set sold in the UK today is the combi drill and impact driver ‘twin kit’. Whether you’re a have-a-go handyman or an experienced tradesperson, you’ll almost certainly have heard of, if not used, an impact driver and a drill. Impact Driver vs Drill: which one do I need?
