What is a Percussion Drill?

It can be easy to confuse a percussion drill with a hammer drill especially when many cordless drills have the picture of a hammer on the function dial. But there is a huge difference between a hammer drill and a percussion drill with hammer function. Having said that, for the average DIY enthusiast or homeowner who is looking to do straightforward home repairs and maintenance, a percussion drill with hammer function might do the job you need. Why?


First off, percussion drills with hammer function DO have the ability to drill into concrete which makes them a handy power tool to have around the home if you need to drill into walls, hard tiles and even concrete lintels that are found above windows and doors. But a percussion drill with hammer function cannot drill into reinforced concrete, so if you need to drill into concrete beams, concrete slabs or other reinforced concrete, you will need to use a hammer drill.







When using a percussion drill with hammer function, it is essential to ensure that the hole being drilled is cleaned out continuously during the drilling process. This will remove any dust or rubble that will otherwise interfere with the impact of the drill bit on the surface of the material being drilled.



The hammer action on a percussion drill only works in the axial direction and very little in the actual forward thrust of the drill bit. This means that as long as the material being drilled is not reinforced and not extremely dense, a percussion drill in conjunction with a quality masonry drill bit will do the job.

This means that drilling into concrete requires less effort than when using a percussion drill. The Festool TPC cordless percussion drill
