Power combi drill tools for drilling and screwdriving for DIYers
Whether you're assembling furniture, hanging a picture or changing your tyres twice a year, there are many everyday situations where a combi drill comes in handy. Bosch has the right combi drill for a wide range of uses, with both cordless and corded combi drill options available. In addition to dedicated screwdrivers and drill drivers, there are also versatile combination tools – the combi drill combines both drilling and screwdriving functions in one device, and its advantage is clear: after drilling a hole, you can drive in the screw straight away without changing tools.
Drilling and screwdriving tools: what to consider when choosing
Wood, metal, masonry or concrete – before purchasing a combi drill or other power tool, you should consider exactly what you want to use it for, as different uses place different demands on the tool.
Consider: what purpose should the combi drill tool serve?
If you simply want to replace a manual screwdriver with an electric helper, a cordless screwdriver is a good choice. DIY enthusiasts who occasionally want to drill holes in walls or other workpieces will also need a drill. It makes sense to invest in a combi drill, which handles many everyday tasks with ease.
For specialist tasks such as changing wheels or chiselling work, all-rounders can sometimes reach their limits. That's when specialist power tools like the cordless impact driver or rotary hammer are needed.
What material will you be working with while using a combi drill?
In addition to the intended use, the material you'll be working with is crucial when deciding on a tool. For light drilling and screwdriving tasks in soft materials, a cordless combi drill is sufficient. The harder the surface, the more power the tool needs. The comprehensive drill guide from Bosch provides helpful information on drilling and fixing correctly in wood, metal and more.
When choosing a combi drill, torque and speed specifications are particularly important. Drilling requires high speeds and low torque, whilst screwdriving requires the opposite.
- Speed: The speed at which the tool rotates determines how quickly it can cut through materials and the quality of the hole produced. A higher speed enables faster drilling and smoother, cleaner holes. A lower speed may be better suited to certain materials or delicate tasks. Choosing the right speed for the material and drill bit size is crucial to ensure optimal drilling performance, avoid damage to the material and maximise the tool's lifespan.
- Torque: Torque, measured in Newton metres (Nm), determines the rotational force with which screws are driven into materials. Sufficient torque ensures a secure fastening, whilst insufficient torque can result in loose screws. Adjustable torque settings prevent over-tightening or under-tightening, provide better control and reduce the risk of damage. Depending on the material, a soft torque setting may be required.
Some drilling tools are also equipped with hammer or impact functions:
- Hammer function: The hammer function is a clutch system that generates rotational force combined with a hammering action, making it suitable for drilling through materials such as masonry, hollow bricks or aerated concrete. When the hammer function is deactivated, the tool can be used like a standard combi drill.
- Rotary hammer function: The rotary hammer function of an SDS drill provides a powerful hammering action in addition to the rotational movement. The rotary hammer breaks up hard materials such as concrete and stone, enabling faster drilling. By combining hammering and rotation, it effectively handles demanding drilling tasks. The hammer function must be switched off when working with delicate or soft materials such as aerated concrete to avoid damage.
Which drilling and screwdriving tools are suitable for which application?
All tools with a chuck are primarily designed to do one thing: drill holes in various materials. Thanks to a wide range of attachments, they're suitable for the most diverse applications – see accessories for drilling and accessories for screwdriving. The terms drill or cordless screwdriver are often used interchangeably for power tools that may look similar but differ significantly in function and performance.
Cordless or corded? Choosing the right power source
For DIY enthusiasts who prefer not to worry about battery life, a corded combi drill is an excellent choice. Mains-powered combi drills from Bosch deliver consistent power for extended drilling sessions, making them ideal for larger projects where uninterrupted performance matters.
