How to Choose the Best Rotary Hammer Drill for Granite?
When it comes to working with granite, having the right tools is essential. Not only does granite require special care to avoid damage, but it is also one of the most challenging materials to drill.
And, choosing the best hammer drill for granite is a crucial decision. There are a few key factors to keep in mind when making your choice:
Type of the Hammer Drill
There are two major types of rotary hammer drills according to their power source: Cordless (battery-powered) and Corded (electric). Pneumatic and fuel-powered models are also available, but they are not as common.
To ensure cordless hammer drills compatibility, make sure that the voltage of a battery is the same as the voltage of the drill. For example, if the battery is 18 volts, then the drill must also be 18 volts.
And for corded compatibility, make sure that the amperage of the power source is the same as or greater than the amperage requirement of the drill. For example, if the power source is 15 amps, the drill should also be 15 amps or less.
You need to keep a few things in mind when choosing a rotary hammer drill that’s tough enough for granite:
First, the drill should have a high-quality driving force that is designed for heavy-duty use. Second, the drill should have a robust chassis that can withstand repeated impact. The drill bit should be made of a material that is tough enough to penetrate granite.
You should also take the size and weight of the drill into consideration. A heavier and larger drill may be more difficult to maneuver, but it will also be more stable and have more power.
Powerful Brushless Motor
There are a few different ways to measure the power of a brushless motor, but the most accurate way is to use a dynamometer.
By measuring the amount of torque and speed that the motor can produce, a dynamometer can give you a good indication of its overall power.
Remember, brushless motors’ power output can vary depending on how they’re used. For example, a motor that is used for drilling granite will likely have a different power output than one that is used for drilling concrete.
The best way to determine the speed control on a rotary hammer drill used for granite is to use the formula Vc = n x D^2 x N/60.
Vc is the cutting speed, n is the number of teeth on the drill bit, D is the diameter of the hole being drilled, and N is the revolutions per minute (RPM) of the drill.
This formula will give you the optimum speed for drilling through granite without causing too much wear and tear on your bit. Keep in mind that each type of granite is different and may require a different speed to drill through.
In order to break through hard materials such as granite, the drill must generate enough force to break through them. Several methods exist for measuring impact energy, but one of the most common is to use the joules rating.
This is a measure of the amount of energy that is delivered with each blow of the drill, and it can be a useful way to compare different models.
Another way is to look at the weight of the drill. Heavier drills will typically have more impact energy than lighter ones, making them better suited for drilling through tougher materials.
RPM, Torque, BPM
To determine the RPM, or Revolutions Per Minute, of your drill, you’ll need to take the no-load speed and multiply it by two. The no-load speed is the number of times the drill bit turns when the motor is running but not under any load.
To calculate the torque or twisting force, you’ll need to take the stall torque and divide it by two. The stall torque is the amount of force required to keep the bit from turning when it’s under a load.
Finally, to calculate the BPM, or Beats Per Minute, just divide it by four. The BPM is a measure of how often the bit strikes the material being drilled.
Active Vibration Control (AVC)
The AVC of a rotary hammer drill is measured in terms of the amount of vibration that is reduced. There are three main ways to reduce vibration:
- By using a vibration-damping handle
- By using a vibration-damping sleeve
- By using a vibration-damping bit
It’s all about the handle of the drill when it comes to reducing vibration. The sleeve and bit work together to further reduce vibration. Just remember that the AVC will only work if all three components are used together.
The depth gauge on a rotary hammer drill is used to set the depth of the hole being drilled. There are two main types of depth gauges:
- Those that are adjustable
- Those that are fixed
The adjustable depth gauges are the more popular type, as they allow you to determine the hole depth before drilling.
Fixed depth gauges can be more accurate but are less versatile. You can remove the depth gauge from the drill if you need to, but it’s not necessary.
There are a few things you need to take into consideration when determining the auxiliary handle of granite rotary hammer drills.
- The first is the weight of the drill. A heavier drill will require a sturdier handle, so make sure to take that into account.
- Second, the bit size. A larger bit will require a longer handle, so you’ll need to factor that in as well.
- And finally, you’ll need to consider the type of grip you prefer.
Easy to Operate
In order to figure out how easy it is to operate a granite rotary hammer drill, consider these factors.
First, consider the size and weight of the drill. A heavy-duty drill may be more complicated to operate than a lighter model. Second, think about the power source.
A corded drill will be harder to maneuver than a cordless hammer drill. Take into account the features of the drill. A drill with a lot of bells and whistles may have more complicated controls than a basic model.
First and foremost, the tool should be comfortable to hold and operate. The handle should be positioned so that your hand is in a neutral position, and the controls should be within easy reach.
As well, the weight of the tool should be evenly distributed so that it doesn’t cause fatigue during extended use.
Another important consideration is the vibration level of the tool. High levels of vibration can cause numbness and tingle in the hands, so it’s important to choose a model with low vibration levels.
Finally, you’ll want to consider the noise level of the tool. If you’ll be using it in an enclosed space, or if you have sensitive hearing, you’ll need to choose a model that produces minimal noise.
By taking all of these factors into account, you can be sure of selecting the best rotary hammer drill for concrete or a variety of granite.
Frequently Asked Questions
There are a few common questions that come up when purchasing a rotary hammer drill. Here are a few of the best ones, along with their answers.
1. What is an SDS Hammer Drill?
An SDS hammer drill is a specialized power tool specifically designed for drilling applications. These drills are best suited for drilling through materials such as steel, granite, brick, masonry, and concrete. SDS drills are chisel drills or hammer drills.
2. What Is the Difference between SDS Plus and SDS Max?
SDS Plus and SDS Max rotary hammer drill bits can be used with an SDS drill. The main difference between the two is that SDS Max bits have a larger shank (18mm), which allows them to withstand more torque and force.
This makes them better suited for tougher masonry work. SDS Plus bits are shorter in length (10mm) and also good for heavier-duty and more compact diameter holes.
3. What’s the Difference between Rotary Hammer and Hammer Drill?
A rotary hammer is a great tool for heavy-duty jobs that require more power than a hammer drill can offer. Its design makes it perfect for pounding away at concrete, brick, and other hard surfaces.
The flying piston delivers a lot of impact force to the bit, allowing it to quickly break through tough materials.
4. Are All Rotary Hammer Bits the Same?
Rotary hammer bits can be differentiated by their connection type. There are three types: SDS-Plus, SDS-Max, and Spline.
Be sure to purchase the bit that matches your hammer’s connection type, as they are not interchangeable. The diameter of the hole that needs to be drilled will dictate which type of bit is necessary.
Now you know everything there is to know about rotary hammer drills. While searching for the best rotary hammer drill for granite, keep in mind the product reviews we discussed in this article. Choose one carefully for your job as well.
Size, weight, power source, and features of the tool should all be considered. A power tool should also have an ergonomic design and low vibration levels. Last but not least, make sure you purchase the correct drill bit for the project you are working on.
