Drilling Into Concrete With Impact Driver

Here s how to use an impact drill to drill into concrete.

Drilling into concrete with impact driver.

Start drilling with only a little pressure. Want to bore holes with an impact driver. To start drilling select the smallest masonry drill bit and push the masonry drill bit into the location you want to drill. Insert the concrete screw into the anchor and drive into the wall until secure.

Slip one into your impact driver then make some holes before driving screws. Hammer drills and impact drivers have different applications a hammer drill is used to to drill into hard surfaces like cement and concrete while an impact driver is used to install and remove bolts and screws. Use impact driver masonry bits. Impact drill an impact drill on the other hand delivers impact in a rotational direction rather than back and forth in the axial direction as illustrated below.

A handful of companies offer collections of drill bits that have the kind of one quarter inch hex shank that screw driver bits use. An impact driver is a totally different beast. Mark the center of your hole and use your smallest masonry bit to drill applying gentle but steady pressure. Don t worry if you don t own all of the tools needed to complete this diy project.

It uses a two jagged discs illustrated below to drive the drill bit back and forth into the concrete causing the hammer drill to hammer the concrete and pulverize it while it spins. Remove any concrete dust then press the anchor into the hole until it is flush with the surface. Drivers that are impact only are neither efficient nor practical for creating holes in concrete. Both are very powerful tools but use different mechanisms of action.

A roto hammer drill or impact driver will likely destroy the brick. Mark the location of the hole you want to drill and mark it with a pencil. It hits down when it drives right synchronised the way a hammer drill isn t. Get a whole set of masonry bits that are designed for an impact hammer.

If the concrete is too old and hard to use then drill an oversize hole and use an epoxy in fastening expansion bolt or the good old fashion expansion plug. For brick and smaller holes in concrete a variable speed drill with a masonry bit is the proper tool.

Since that is its function it may not give you the same results that a hammer drill or a rotary hammer. This is because standard drills are specifically designed to drill while the impact driver s main function is drive fasteners. Yes it can but its primary function is to drive and remove screws from the concrete. A hammer drill uses a hammer like action on the drill bit to drive it into the hard surface.
