Types of drills and their uses

Learn about the types of drills and how to use them

Drill loosen and tighten screws

Provides piercing pivot movement and acts as a screwdriver. It does not work as a drill hammer. The cordless drill (charging drill) can be used in most household tasks that require quick drilling, such as drilling wood, interior walls , and metal.

Multi-use drill

It works as a drill bit for high-speed torque drilling, as a screwdriver for tightening and loosening screws, and as a drill bit.

The hammer feature that this type possesses distinguishes the mixed drill (multi-application) from other types of drills and drills that work as a screwdriver for tightening and loosening screws.

This also means that this type of drill is capable of drilling through very hard surfaces that ordinary drills cannot drill and pass through. You'll need a multi-function drill if you want to drill through concrete.

Hammer feature - hammer

This feature allows you to drill through materials such as cement

The hammer feature complements the torque generated during the drilling process, and this allows the drill to hit the surface a thousand times per minute and to penetrate high-density surfaces. Use tungsten carbide edged drills when using hammer drills

Axial drilling feature

Pivot drills are ideal for performing ordinary household chores that ordinary people might do themselves. For example, drilling holes in the wall to hang picture frames.

This type relies on fast rotation (up to 3000 rpm). Therefore, it is the ideal choice for drilling small holes and for drilling through fragile materials such as wood, metal, and plastic. So you won't need the hammer feature.

Screw tightening and loosening feature

The hammer drill also comes with a slow speed feature for tightening and loosening screws. This provides slow speeds with extra turning power

This type rotates at up to 3,000 revolutions per minute, but to obtain more power, the hammer feature in this type will increase its rotation speed to reach 40,000 revolutions per minute.

The problem with using this type of drill is that it is not suitable for daily household jobs, or drilling through limestone or light cement. However, drilling through hard stone such as granite will result in vibrations and noise due to the intense pressure from the drilling process, and because you need greater driving force to operate the hammer feature in it.
