The multi-function drill allows users to use both drilling and screwdriving functions. See the article below to find out specifically what a multi-function drill is, and its features and uses, please!
What is a multi-function drill?
A multi-function drill is a hand-held tool that can perform many different jobs such as drilling, punching or swirling to create holes through hard materials such as walls, stones, metal, …
This is an indispensable equipment in fields such as construction, mechanics, architectural construction, and interior. In addition, the multi-function drill is also an ideal household tool for drilling and screwing hanging pictures, fixing shelves, hanging curtains, …
Currently, on the market, there are many types of multi-function drills with different structures and uses. Among them, the most popular are multi-purpose drills such as battery-powered, electric, and steam-powered.
Features of multi-function drill
Electric type
The electric multi-function drill is the most popular product on the market today. This device has many uses such as drilling walls, chiseling metal, drilling wood, and turning screws.
Because of its popularity, the accessories of this drill are also easy to find and replace. The cost of a cordless drill is also cheaper than a battery-powered or steam-powered type.
Battery type
The battery-powered multi-function drill makes work more flexible, especially in small spaces. This product also has powerful capacity, neat design, easy operation, changing internal components, and can be taken with you anywhere.
There are 3 basic types of batteries used for multi-purpose drills, including Li-ion , NiCd and NiMH batteries. For home drills, Li-ion batteries are the most popular because of their modern production technology, light weight and stable operation.
Steam type
The multi-function steam drill has a very fast speed and strong force with the rotation speed of the drill bit can be greater than 1800 rpm . This device uses about 4CFM of air, often comes with accessories such as a drill head or a specialized compressed air tank.
The multi-function steam drill is mainly used in factories or construction sites. The drill bit diameter is usually in the range of 1.5mm – 10mm , suitable for many different work purposes.
Uses of a multi-function drill
Conventional drilling function
With this function, the drill motor will generate torque to make the drill rotate and generate force to drill holes, through the surface of the object you want to drill.
Cutting function
With a multi-function drill, you can convert the drill bit to the cutting edge that suits your needs. This saves costs because you do not need to buy a cutting machine and still ensure work efficiency.
Grinding function
As well as the cutting function, the drill bit of the all-in-one drill can be converted into a grinder blade for even, straight, fast and safe grinding of surfaces.
Rotary hammer drill function
When the rotary hammer drill function is turned on, in addition to the torque force (M), the drill will simultaneously generate additional striking force (F) along the drill bit axis. As a result, the device is strengthened and has the ability to destroy much faster.
Chisel function
The multi-function drill also has a chisel function with the use of destroying hard materials (such as cement, concrete, …) by applying a continuous force in and out in the direction along the axis of the drill.
The difference between the functions of the multi-function drill
Towards the direction of impact
The function of rotary hammer drilling and impact drilling (or dynamic drilling) has a fundamental difference in the direction in which the force is applied to the drilling operation.
Rotary hammer drills exert a large force directly along the drill bit as soon as it hits the surface of the workpiece, much like hitting a hammer directly on the head of a screw.
Meanwhile, impact drills apply force in a direction perpendicular to the drill bit , which feels like increasing force on a wrench around the screw.
About the mechanism
The hammer drill function is operated based on the mechanism that is the mechanical impact of the hammer through a piston actuated by the drill motor. This piston will compress the metal spring, thereby, causing a large force to act on the drill shaft.
Each time the above force occurs is counted as 1 impact, measured in units of impact / minute (bpm). Compared with impact drilling function, this index in rotary hammer drill is much smaller .
