Features to Look for in a Demolition Hammer 5kg 

When considering a purchase of a 5kg demolition hammer, understanding the key features can help you make an informed decision and select a hammer that meets your specific needs. 

Power Source: Corded vs. Cordless

Corded Demolition Hammers:

  • Consistent Power: Since they draw power directly from an electrical outlet, they can maintain a steady performance throughout their operation.
  • Unlimited Run Time: With corded models, you can work without interruptions as long as you have access to an electrical outlet.
  • Weight: Generally, corded hammers might be slightly lighter since they don’t carry a battery pack.
  • Limitation in Mobility: The primary downside is the restriction in movement. The length of the cord limits how far you can move, and you always need to be near an electrical outlet.

Cordless Demolition Hammers:

  • Mobility: You can use a cordless hammer anywhere, even in places without direct access to electricity.
  • Convenience: Without a cord to worry about, you have a reduced tripping hazard, making the job site potentially safer.
  • Battery Life: Modern batteries have improved significantly but they still have a limited run time. It’s essential to have spare batteries or ensure they are fully charged before a long task.
  • Weight: Cordless models might be slightly heavier due to the added weight of the battery.

When deciding between corded and cordless, consider your work environment. If you often work in remote locations or places without easy access to power, cordless might be the way to go. A corded model would be ideal if you’re mainly in one spot and prefer consistent, uninterrupted power.

Motor Strength and RPM

Motor Strength:

  • Power Rating: Usually measured in watts or amps, the power rating indicates the tool’s capacity to handle tough jobs. A higher power rating generally means a more potent demolition hammer capable of breaking harder materials.
  • Durability: A strong motor means the tool will likely last longer and withstand heavy-duty tasks without overheating or breaking down.

RPM (Revolutions Per Minute):

  • Speed vs. Torque: Higher RPMs usually mean the hammer can deliver blows at a faster rate. This can be especially useful when chipping away at softer materials. However, torque (the force with which the hammer hits) might be more crucial for breaking tougher materials than speed.
  • Adjustable RPMs: Some demolition hammers come with adjustable RPM settings. This feature allows the user to choose the right speed for different tasks.
  • Efficiency: Faster RPMs can mean quicker completion of tasks, but it’s essential to ensure that the speed doesn’t compromise the tool’s effectiveness in breaking materials.

Vibration Control and User Comfort

A hammer that doesn’t prioritize user comfort can lead to early fatigue, decreased precision, and even long-term health issues. 

Vibration Control:

  • Some modern demolition hammers incorporate advanced anti-vibration systems. These systems can significantly reduce the amount of vibration transferred from the tool to the user.
  • Reduced vibration enhances user comfort and decreases the risk of conditions like hand-arm vibration syndrome, a painful and potentially debilitating disorder.

Handle Design and Ergonomics:

  • Soft Grip Handles: These can help dampen vibrations and provide a more comfortable hold, leading to better control and less strain on the hands.
  • Auxiliary Handle: An additional side handle can offer better control during use, especially during more robust operations. It allows the user to switch or use both hands for better leverage and precision.
  • Balanced Weight Distribution: A well-balanced tool ensures that the user doesn’t have to exert excess force to control the tool.

Durability and Material Composition

Durability is not just about getting value for money; it also means consistent performance over time. 

Material Quality:

  • High-quality metals like hardened steel or aluminum alloys in critical components ensure that the hammer can withstand the stress of demolition tasks without deforming or breaking.
  • Durable casings or housings can protect the internal components of the hammer from dust, debris, and even accidental drops, prolonging the tool’s lifespan.

Sealed Components:

  • Demolition tasks can generate significant amounts of dust and debris. Sealed systems, especially around the motor and moving parts, prevent these from entering the tool and causing wear or damage.
  • Sealed components increase durability and maintain consistent performance by preventing foreign particles from interfering with the tool’s operation.

Brushless Motor:

  • Compared to brushed ones, brushless motors often offer better performance, efficiency, and lifespan. They have fewer wearing components, which means they’re less likely to break down and require less maintenance.
  • These motors generally produce less heat, which can benefit both the tool’s lifespan and the user’s comfort.

Warranty and Brand Reputation:

  • Guarantee: A good warranty can indicate that the manufacturer has confidence in the product’s durability. It also provides peace of mind when you know any defects or issues will be addressed.
  • Reputation: Established brands with a history of producing quality tools can be more trustworthy in terms of durability and performance.
safety tips in using demolition hammer 5kg

Safety First: Using a 5kg Demolition Hammer Safely

Making sure you operate these tools safely can prevent injuries, improve the efficiency of the job, and ensure the longevity of the tool itself. 

Protective Gear

  • Goggles: Look for safety goggles that offer a snug fit, are resistant to impacts, and preferably have anti-fog features. Wraparound designs can provide additional side protection.
  • Gloves: Opt for gloves designed for heavy-duty tasks. These usually feature reinforced palms and fingertips and are made of durable materials that don’t compromise flexibility.
  • Ear Protection: Earplugs and earmuffs are the most common choices. Earmuffs tend to offer higher protection but might be bulkier. Earplugs are more discrete and can be just as effective if used correctly. 

Proper Handling and Posture

  • Holding the Tool: Most demolition hammers are designed for two-handed operation. Using both hands offers better control, reduces fatigue, and minimizes the risk of the tool slipping or going off course. A firm grip ensures control, but squeezing the tool too tightly can increase hand fatigue and the effects of vibration.
  • Posture and Stance: Plant your feet shoulder-width apart to maintain better balance, especially when working on uneven surfaces or applying force. When you need to get lower, bend your knees rather than leaning forward from the waist. Holding the hammer closer to your body can reduce strain on your arms and back. It also allows for better control and precision.

Tips for Efficient and Effective Hammer Usage

seasoned professional or a DIY enthusiast, these tips can help you get the most out of your 5kg demolition hammer.

  1. Understanding the Material

Different materials require different approaches. For instance, breaking through concrete might require more force and patience than tile or plaster.

  1. Choose the Right Bit

Demolition hammers come with a variety of bits, each designed for a specific type of work. Whether it’s a point-tip, flat-tip, or a chisel, ensure you pick the right bit for the job. Using the wrong bit not only reduces efficiency but can also damage the tool or the material.

Maintenance and Longevity

Proper care can drastically increase the tool’s lifespan, ensure consistent performance, and reduce the potential for accidents due to malfunctions. 

Cleaning and Storing Your Demolition Hammer

Cleaning After Each Use:

One of the primary culprits that can reduce a tool’s lifespan is the accumulation of dust and debris, especially in a tool like a demolition hammer that often operates in dusty environments. Remove dust and debris from the tool’s exterior after each use using a soft brush or compressed air. Ensure vents and moving parts are free from blockages.

The chisel or bit is a component that undergoes significant wear. Clean it thoroughly and inspect it for signs of excessive wear or damage. A worn-out chisel can affect the hammer’s performance and might even damage the tool.


Regular lubrication ensures that moving parts operate smoothly, reduce wear, and help dissipate heat more efficiently. Check the user manual for specific lubrication guidelines. Some models might require periodic lubrication, while others might come with sealed parts that need less frequent attention. Always use the recommended type of lubricant.

Inspect the Cord and Plug:

Check the power cord for signs of fraying, cuts, or nicks. Damaged cords can be hazardous and should be replaced immediately. Also, inspect the plug for any damage or wear.

For cordless demolition hammers, ensure the battery terminals are clean and corrosion-free. It’s also a good practice to keep batteries out of extreme temperatures.

proper maintenance of a demolition hammer 5kg


Always store your demolition hammer in a dry, clean place, preferably away from direct sunlight and extreme temperatures. Moist environments can lead to rusting or corrosion. If your tool comes with a protective case, it’s best to use it for storage. Store the tool on a shelf or in a cabinet, away from ground-level moisture and dust if possible.

  1. Start with Lower Power

When starting a new task, especially on an unfamiliar material, begin with a lower power setting. This approach allows you to gauge the material’s resistance and adjust accordingly. Once comfortable, you can increase the power for quicker results.

  1. Maintain a Steady Angle

While the exact angle can vary based on the task, maintaining a consistent angle ensures even breakage and reduces the chances of the bit getting stuck. A typical recommendation is to start at a slight angle and adjust as necessary based on the results.

  1. Let the Tool Do the Work

Avoid applying excessive downward pressure. Instead, let the weight and power of the tool do the work. 

  1. Take Regular Breaks

Continuous use can not only tire you out but also overheat the tool. It’s recommended to take short breaks, especially during intensive tasks. 

  1. Avoid Prolonged Use in One Spot

If you find that you’re not making progress in a particular spot, it’s beneficial to move to a different area and return later. Continuously hammering at one resistant spot can wear out the bit and overstrain the tool.

  1. Regularly Check the Bit

During extended tasks, periodically check the bit for signs of excessive wear or damage. A damaged or blunt bit can drastically reduce efficiency and even risk damage to the tool.
