Knowing and understanding the differences between drill types is important as knowing what each will allow you do makes sure you buy the right drill for your line of work.
In this Toolstop Guide, we’ll look at combi-drills and explain what they are, what they do and why you should buy one.
What Makes a Combi-Drill Different from a Drill Driver?
This is an important question to answer as it can be easy to get confused between the two different types. A drill driver will drive screws and drill holes into hard or softwood and plastic, laminates, etc. A combi-drill will do all of these applications but will also drill into masonry, concrete and steel.
If you need to drill into masonry or steel, you need a combi-drill.
The reason a combi-drill can drill into masonry and steel is due to the hammer function provided by the motor to the chuck. The chuck spins but impacts – or a hammering action – punch the bit backwards and forwards at very high speeds to “punch” into the material being drilled.
Are Hammer Drill Drivers the Same Thing as Combi-Drills?
This is where the matter can be a little confusing as some manufacturers label their combi-drills with such terms as “drill driver with hammer function”. But yes, a hammer drill driver is the same thing as a combi-drill. You’re getting 3 modes: drilling, driving, and drilling with hammer action.
However, a combi-drill isn’t the same thing as an impact driver. Again, this can be a little confusing at first, so we asked Eric from Bosch to explain the key differences, which you can watch below.
Should I Buy a Combi-Drill?
Given what we’ve outlined above, if you need a drill driver that will also put holes in concrete or brick for 13mm fixings, then yes. If you need to drill holes in metal, yes, you need a combi-drill. But which one is right for you? As always, this will depend in part on brand loyalty and on the battery platform you’ve already invested in. If you have a stack of batteries from one brand, then opting for a body-only combi-drill will be the most cost effective way of adding one to your kit. Other factors to consider include the build quality of the combi-drill. Is the chuck metal or plastic? Is the motor brushless, ensuring longer runtimes, more power and durability?
