What Is a Low Vibration Drill?
A low vibration drill is a cutting tool that functions by bit rotation rather than impact as with conventional drills.
Since they do not require impact, low vibration drills significantly reduce noise caused by vibration and impact, resulting in a significantly quieter work environment.
Low vibration drills also reduce the impact on the base material, reducing chipping, scraping, and other damage, and improving the quality of the finished product.
Low vibration drills address the problems that come with conventional drills and are used in many workplaces to facilitate quiet, high-quality drilling.
Uses of Low Vibration Drills
Low vibration drills are used for work in buildings where people are present because they do not generate noise. In conventional drilling, vibration and impact from blows and noise are generated, requiring adjustments to work days and times. However, with low vibration drills, no noise is generated, making it easier to work even when people are present in the same building.
Low vibration drills are especially useful in buildings where many people gather, such as office buildings, condominiums, and hospitals, and when drilling on concrete walls and floors.
Principle of Low Vibration Drills
The principle of low vibration drills is that a bit made of diamond or other hard material at the tip of the drill rotates at high speed to perform the drilling process. This minimizes blows, impacts, and vibrations.
In addition, water or gas is sprayed during the operation to cool the frictional heat generated by the high-speed rotation of the bit. This prevents the drill from heating up and allows work to proceed efficiently.
A rubber push portion is also installed to mitigate the push force, further reducing vibration. The size of the bit can also be changed to adjust the size of the hole to be drilled.
The combination of the low vibration drill, the high-speed rotating bit, the cooling system, and the rubber push part allows for efficient drilling while suppressing vibration. The noise and vibration problems that occur with conventional drills have been solved, allowing work to be performed comfortably at a variety of sites.
Types of Low Vibration Drills
There are three main types of low vibration drills: diamond core drills, carbide core drills, and hammer drills.
1. Diamond Core Drill
Diamond core drills are drills with a pit made of diamond at the tip. They are suitable for drilling holes in hard materials. They can effectively drill holes in concrete, stone, tiles, etc. Additionally, the high-speed rotation and cooling systems enable accurate drilling with minimal vibration.
2. Carbide Core Drill
Carbide core drills have a tungsten carbide pit at the tip and are more economical than typical low vibration drills. They are suitable for machining concrete, block, and brick, and offers superior durability and cutting performance compared to diamond core drills.
3. Hammer Drill
Hammer drills are a type of drill that fall between conventional percussion drills and low vibration drills, and can be operated electrically or pneumatically. They do not have a bit at the tip; instead, drilling is achieved by striking simultaneously with rotation.
As a result, some vibration is generated, but is less than that of conventional impact-type drills. It is mainly suitable for drilling holes in soft materials such as wood, metal, and plastic.
