Things to keep in mind before buying a rock drill.


A rock drill is an essential tool for any construction site, as it allows you to bore holes in the rock. You will find that there are different types of rock drill rigs on the market, each with its features. However, they all have one thing in common: they help you work faster and more efficiently than using other means of drilling holes would allow. Many factors should be considered before you buy a rock drill, such as the diameter of the borehole, drilling depth and rotation speed.

Consider the diameter of the borehole.

The diameter of the borehole is an important factor in determining the size of the rock drill you need. A larger rock drill can drill a larger hole than a smaller one, but it’s not as simple as choosing the biggest one available. The depth at which you want to drill must also be considered since a large borehole might take longer to reach from a surface than from deep underground.

Once you have considered all these factors, determine what type of rock drill best suits your needs:

Consider drilling depth.

A rock drill is designed for drilling holes into rocks. The hole depth is an important factor to consider before you buy rock drills, as it determines how much power you need and the size of the drill bit you need.

Consider the rotation speed.

A rock drill’s rotation speed (RPM) is the rate at which a bit spins inside the machine. A higher rotation speed means faster drilling and more torque, but it also means that you have to be careful not to damage soft rock, or you’ll risk breaking your bit.

Consider the power of the rock drill.

The capacity of a rock drill is measured in pounds per square inch (psi). The higher the psi, the more pressure you can pack into a hole. You must consider how much strength you will need to break through the rock and what kind of work conditions your drill will be operating in. For example, if you’re drilling into hard limestone but only have an 8-inch hole spade at your disposal and no bracing, then you won’t be able to apply enough force on your drill to cause any significant damage; however, if you were using a jackhammer with tons of power behind it and could control where it was going every second that would be another story entirely!

So what do these numbers mean? Let’s break them down:

  • Friction losses are caused by sliding materials against one another during operation. This causes heat loss due to friction resistance between surfaces rubbing together (this is why your car gets hot when idling too long). This heat causes wear on all moving parts within the system, including cutting edges.


The first thing is to decide what kind of work you will do with the rock drill. If you are just drilling holes in concrete or bricks for small projects, then an air-powered drill will be sufficient for your needs. However, suppose you need to drill large diameter holes or need more power than an air-powered unit can offer. It might be time to look at hydraulic-powered models instead, as they tend to be more powerful while still being portable enough not to get in your way when working outside around other people or animals who may not want dust particles flying around them all day long.
