Impact Drivers and Hammer Drills.
Tools that are very similar but function differently. Impact Drivers are slightly lighter weight and are more suitable for screwing. Hammer Drills are more versatile and suitable for making holes in metal and concrete.
What our customers say
"I like using impact drivers because we have many electrical panel connections. The tool is lightweight and able to get the job done quickly" - Mr Tang, Electrician
"The hammer drill helps us to do simple duct fixing and also light anchoring on the wall. One tool solves everything" - Mr Lee, Renovation contractor
Which of them should you rely on? Well it really depends what you are fixing and the material youre working on!
Can I just have a cheat sheet to see what's best? Yes! Here it is.
|Material||Impact Driver||Hammer Drill|
|Concrete||Nope. No knocking power||Yes. Please use the hammer function.|
To work on concrete, you will ALWAYS need a hammer drill. Hammer drills are good for light concrete work (think putting screws into the wall to hang paintings). For heavy concrete work you will still need a rotary hammer.
Its all in the head. Literally.
Impact drivers have 1/4" hex heads. This means you need a bit set (such as one from Heytec) as attachments. Bit holders slot into this hex head, and you can choose from a wide variety of bits for attachments.
These attachments fix to a variety of heads including TORX heads, hex heads as well as sockets for nuts.
In short - if you are ONLY fixing screws into anything other than concrete: use an impact driver.
Hammer Drills have 13mm drill chucks. Modern hammer drills come with keyless chucks. You can attach drill bits for concrete, wood and metal, or hole saws to this chuck for any application.
In short - if you are making holes or drilling concrete, use a hammer drill. You can also use hammer drills with the bit sets described above for screws
