Carpenters, construction specialists, electricians and handymen in any place know the fact that the most essential tools, which they can use, are the impact drivers and drills. Two special drilling tools, which have some additional punch and can drill solid substances, are the impact driver and the hammer drill. Though both of them offer similar roles and carry out similar works, there are some differences, seen between the two tools.
Course of the energy
The energy, which is applied in any common drill, is completely rotational. The top part of hammer drill rotates, and it twists the screwdriver or drill bit into the drill’s chuck. When you like more downward force for pushing any bit deep into the surface of working, you need to give your own muscles. Any impact driver is, however, competent to apply downward power with some taps.
While you start to drill anything for the first time, the spring spins at a speed like the weight that is near anvil. But, when the resistance becomes higher, the weight starts rotating very slowly. When it occurs, the motor may revolve at its natural speed that maintains the rotation of the spring at the natural rate.
Torque and power
With the use of both impact drivers and hammer drills, you can have higher voltage if they are more powerful. The drill with 20 volts can give significantly more amount of power than that of any 12-volt model. At every level of voltage, the blend of impact and rotation in an impact driver provides more amount of torque. For this reason, impact drivers may be competent to place long coils deep into any material.
Size and versatility
Drills can be more preferable in terms of versatility. It is because they possess one flexible chuck that can make the tool well-matched with screwdrivers, drill bits, mortar blenders and some other things. Impact drivers allow the attachments that have six-sided rod of a very standard size. In addition to it, impact drivers may in length shorter, in contrast to the drills. Thus, they suit the tighter parts.
In fact, impact driver consists of three units that cannot be found in your hammer drill-
- Effective compression spring
- T-like anvil
- Impact mass or weight
These are the differences that all you can think of about the impact drivers and hammer drills. An idea on these tools can help you to buy one for your purpose.
