When you have any of these to handle, instead of going through the stressful hammer and chisel method that takes a lot of time, if you need a more comfortable means, a hammer drill is your best bet. The hammer drill designed for tough and solid materials like mortars, stones, concrete, bricks.

The hammer drill is not a simple tool, there are several functions you can carry out with it, and chiseling is just one of them. This quality enough complicates it, so we would give some tips on how you can use the hammer drill as a chisel.

The gloves would not only to keep the hands from dangers, but it is also to give you a better grip, and that is why you need a good one (check prices on Amazon.com).

Select your tool

For concrete and Mansory tools, you get various options, depends on what you intend to do with the material, several modes can exploit this options, you have the drill mode, the hammer mode, and the hammer drill mode.

Not all drills have the chiseling function, most of them have the primary capacity to spin the drill bit into a material, but the rotary hammer drill is built with a hammer-only mode which creates high impact energy to perform secondary tasks like breaking up concrete materials or tiles, and primary functions like chiseling and chipping.

Unlike the normal drilling process of marking the spots with a pencil or a marker for accuracy, chiseling cannot assure you of the same level of precision; you might have some rough edges.

Chisel with the right drill bit

Now that you know the right drill to use for chiseling and the mode to set up, one choice you must make is the type and shape of drill bit you would use, which brings us to talk a little about the interface system.

The interface system of a tool determines the types of accessories that can work with them, but one advantage of construction tools is that they are available with several types of interface systems.

For drilling through concrete, a Mansory drill would do justice, but for chiseling, we would recommend you get hex collar bits (check prices on Amazon.com), they are also called hammer steel. They include accessories like drivers, cutters, spades, points, and chisels.

Usually, all of these would be held in place by a redundant ball detent and a collar system to retain it in a single direction. The Hex collar bits are built to be big and heavy enough to beat and break through tough materials. The bits for chiseling have a spade-like end to pull through the Mansory material as the hammer drill beats though it consistently.

The Chiseling process

  • When you need to chisel, set your hammer drill to the hammer-only mode, and begin from a convenient position, the chiseling process is would depend on the project you are carrying out.
  • If you are trying to chisel a path where you want to plant cables or pipes in a wall for a renovation or start holes in concrete, you should begin with the smaller bit. Make the path then step up the bit to a larger one until you attain your target size.
  • When you are removing ceramic tiles, just pick out a chisel bit depending on the size of the tile and turn on your hammer drill and work the process. You also need to clear the debris on the chiseled surface so you can reduce the friction and have a smother work process. Removing debris from your work surface can also help you elongate the lifespan of your drill bit and reduce binding.
  • Another tip of chiseling is to avoid pushing too hard, although it is necessary that you have to apply some amount of pressure so your tool can maintain good contact with the surface, but the beating action of the hammer drill makes it unnecessary to use excessive force to it. No matter how tough the bits might be, too much pressure might break your drill bit.
