How to Choose a Hole Digger?
When purchasing, it is advisable to take into account the characteristics on which the performance depends on different conditions. These parameters include the power, diameter and length of the drill bit, set elements, ergonomics. Quality and usage also affect its lifespan.
The value of the parameter is affected by the volume of the internal combustion engine. The higher it is, the more electricity, depending on the depth and width of the borehole. To get a well, it is recommended to choose units with an indicator of at least 7 – 8 hp. In everyday life, devices with a capacity of up to 3 hp are suitable.
Professional-grade models are often chosen for long-term work on dense soils with rocky patches. Large drills can be mounted on powerful equipment. At the same time, they have a very large weight and torque, so the operator needs to accurately calculate his strength.
#2 Drilling depth and diameter
The standard length of the screw rod is 600 – 800 cm, so to drill deep holes, it is advisable to immediately purchase good quality extension cords, a tripod. Using devices with a capacity of up to 3 HP allows you to take holes with a diameter of 20 – 30 cm and a depth of 200 cm The first value depends on the width of the screw itself.
High-power models are designed for mounting a screw rod with a diameter of 300 – 600 mm. When drilling with such aggregates, large holes will be obtained, which ensures their use for the installation of tall pillars.
#3 Replaceable drill head

If you want to buy good quality components, you will have to pay at least a few hundred dollars. With regular use, it is recommended to sharpen the cutting edge, otherwise the risk of performance loss increases. In this case, any tool for grinding the garden or construction equipment is suitable.
The ease of use of the model depends on the weight of the device and the features of the handle. It is easier for one person to work independently with light equipment. If the weight of the equipment reaches between 30 – 45 kg, then it is designed for use by 2 operators.
The handle should be equipped with a soft rubber pad to prevent hand slipping when drilling. An important criterion for selection is their location. It is recommended to have vibration damping, reversing and braking devices in motor drills. The first reduces kickback in the operator’s hands, the second makes it easier to remove the drill bit from the ground. The brake system eliminates damage to the gearbox when stuck.
Principles of Safe Use of Hole Drilling Machine
Hand-held hole drills work mainly on the force from the rotating shaft of the hacksaw blades impacting the soil layer to create deep holes. The rotational force of the drill bit has a very high rotation speed. Therefore, if you are not careful, it is very easy to have an accident during the excavation process. These accidents often have very serious consequences.
In fact, there have been many cases of accidents, injuries, and even death by the use of an unsafe planting hole digger. Several people were hospitalized in critical condition after being hit by the blade of the hole drill. Just because of being subjective when using a digging machine in the process of growing grapefruit, someone has permanently lost their hands. Drilling machine accidents have very serious consequences.
If you don’t want to take those huge risks, you need to pay special attention to safety rules. They will help you to prevent and avoid unwanted situations from happening. Using any type of machine, safety principles need to be put first.
#1 Safety rules when adding gasoline to a hole drill
The principle of safety attention when adding gasoline to the engine is the first thing that should be put on top. Because they are very easy to cause fire and explosion phenomena, which are dangerous to you and those around you.
- Absolutely do not smoke while adding fuel to the engine. The cigarette butts will fall and cause a fire.
- Do not add fuel while the engine is still operating. Partly because it makes it difficult to add ingredients exactly to the jar. A working part of the machine will generate a huge amount of heat. This amount of heat can affect gasoline, which can also cause an immediate fire or explosion. Therefore, you should turn off the engine and wait a few minutes before filling the tank with gas.
- Do not spill gasoline, take a moderate amount. When you run out of fuel, you continue to add more.
- Do not put gasoline near places with fire.
#2 The principle of distance using the hole digger
For soil drills, when using a planting hole excavator, the distance between the legs and the saw blades is not large. So, just a little accident, you will have an unexpected accident right away.
- Should pay attention to the safe distance between the foot and blade of the drill. Do not put your feet too close to the drill.
- Absolutely do not bring your hands or any part of the body close while the saw blade of the machine is still in operation. Although you have turned off the machine, but with a very high rotation speed, they cannot stop immediately. A lot of people are subjective, bringing their hands or feet close, this is really dangerous.
- Pay attention to firmly hold the machine or move the excavation hole to another location when the soil is too hard or there are many rocks.
#3 Principles of labor protection when using a hole drilling machine
Most people who use home drilling machines do not care about protection issues. But wearing protective gear is very important for your safety.
These safety guidelines are extremely important to anyone using a hole digger. You need to follow them strictly and know better than anything.
