Hammer Drill vs. Traditional Rotary Drill

Using a hammer drill, you can drill holes or insert fasteners in surfaces that are extremely hard or dense. On the other hand, conventional rotary drill cannot stand the toughness of hard surfaces and would break if used on such surfaces. The force produced by hammer drills are higher level forces, and would break the object as required to drill the hole. The masonry materials involved when using these tools include brick, concrete and stone.

Outstanding Features of a Hammer Drill

The most outstanding difference between the hammer drills and the traditional drill is that the former features a movable chuck (a drill's part that functions to hold the bit in place). Unlike the chuck of a regular drill, the chuck of this special drill can move backward and forward over a small distance; this in turn aids in the hammering of the wall while the drills spin. Regardless of its short range movement, the movement of the chuck of this special drill is quite rapid, the outcome is hammering into the wall thousand or hundred times per minute! The masonry or stone is easily broken down with the aid of the hammering motion, paving way for successful and smooth entry of the drill bit. The unit measurement of the power/strength of a hammer drill is IPM – Impacts Per Minute – this stands for the frequency of the chuck hammering into the wall per minute.

If you cannot afford a brand new hammer drill, you can resort to used hammer drill which also has the same capacity and produces the same result as the brand new one. This special drill is mostly employed in applications where it is necessary that the workmen combine the drill with the conventional drill for a higher benefit. The tool normally comes with a switch which is capable of turning off the hammering motion as occasion demands – in essence, the chuck would continue to stay stationary for use where conventional drilling application is required.

The new Bosch Hammer Drill features the most excellent Power-to-Weight Ratio. If you want something easy on the arms and hands, the lightweight 4.2-pound hammer drill from Bosch is perfect. Then, the most excellent power-to-weight performer is the Bosch 1191VSRK – (in its class). Bosch Hammer Drills are superb hammer drills to have in the toolbox.

For those workers who are about to execute jobs that they are not certain of the nature of the surfaces they would encounter, the hammer drill is a wiser option to go with. As a mason, you may not know if the job requires drilling into stone and wood objects; therefore it is wise to choose the tool that can tackle whatever situation you meet.

The special drill may come with electrical power cords. At other times, it comes with a more flexible battery-operated feature.

If you are on budget, you can choose from the used hammer drills; however ensure that you are buying from a reliable source to be sure of the tool's effectiveness.
