Power Tools for the Modern Users
In the previous article”What is the difference between an impact drill bit and a drill bit ?“, we introduced the differences between impact drills and regular drills to help you choose the right drill bit for more efficient work. In this article, we will delve deeper into the topic of hammer drills.For many users, a hammer drill is an indispensable tool. Whether you’re drilling into concrete or chipping away old tile, it makes the job easier and more efficient. In this comprehensive guide, we’re going to delve into everything you need to know and introduce you to a game-changer in the market, the M7 Hammer Drill Cordless DRH-101.
What is a Hammer Drill?
It is a power tool designed for heavy-duty tasks. It’s essentially a drill with a pulsating mechanism that delivers a rapid succession of blows as the drill rotates, enhancing its capacity to bore into hard materials like concrete, stone, or brick.
How Does It Work?
It’s main components are the motor and a pair of ridged discs. When the discs slide past each other, they create a series of rapid impacts, which are then transferred to the drill bit. It’s this hammering action, combined with the rotary motion, that allows a hammer drill to bore into tough materials so effectively.
Which One Do I Need?
Impact Driver vs Hammer Drill
While both tools deliver a pounding force, they serve different purposes. An impact driver’s primary function is to drive screws, while a hammer drill excels at drilling holes in hard materials. If your projects involve lots of drilling into masonry or concrete, a hammer drill would be the better choice.
Brushed or Brushless?
Brushless drills tend to be more efficient, offering longer runtime and less maintenance. However, brushed drills can still be a good choice if you value affordability over performance and durability.
Uses
Installing Fixtures onto Brick Walls
One of its most common uses is to install fixtures onto brick walls. Whether you’re mounting a television, hanging artwork, or installing shelves, it makes the job much easier. The tool’s powerful hammering action allows it to drive screws into brick or concrete, creating a secure anchor for your fixtures.
Laying a Concrete Patio
If you’re thinking of laying a concrete patio, it can be your best friend. It can efficiently drill holes into the concrete for dowels, which help align and hold the slabs together, ensuring your patio is sturdy and well-constructed.
Drilling into Concrete and Stone
Drilling into hard materials such as concrete and stone is no easy feat with a regular drill. However, with its pulsating mechanism,it can tackle this task with relative ease. Whether you’re building a rock garden, installing a stone walkway, or drilling holes in concrete walls for electrical wires or plumbing pipes, this powerful tool can make the job considerably easier.
Demolition Tasks
Some come with a chiseling function that allows them to be used for light demolition tasks. This function stops the rotation of the drill bit and engages only the hammer action, turning your drill into a mini jackhammer. You can use this feature to remove tiles, break up small areas of concrete, or chisel away old plaster.
Woodwork and Metalwork
While they excel at drilling into hard materials, they can also be used for woodwork and metalwork projects. By turning off the hammer function, these drills can be used just like regular drills to bore holes into wood or metal.
Types
There are corded and cordless, each with their own advantages. Corded models offer steady power output but limit mobility. Cordless models offer portability but require battery changes.
Other Variations
Other Variations
Certain hammer drills come equipped with additional features like a chiselling function – adding another level of versatility to this already multi-functional tool.
Decoding Features
They come loaded with features designed to enhance user experience and efficiency. These include variable speed controls, depth stops, auxiliary handles for improved control, and built-in LED lights for working in dimly-lit conditions.
Power Ratings: What Do They Mean?
The power ratings of drills are usually given in watts (for corded) or volts (for cordless). More powerful drills can handle tougher jobs but may be heavier and more costly.
Battery Technology in Cordless Power Tools
Cordless tools rely on rechargeable batteries, with Lithium-ion batteries being the most popular due to their high capacity and longevity.
Key Considerations Before Buying a Hammer Drill
Before investing , consider its power, speed, weight, battery life, and additional features. All these factors will play a role in determining the tool’s performance and your overall user experience.
FAQs
Can I use it as a regular drill?
Yes, most of them come with an option to switch off the hammering function, allowing you to use it as a regular drill. This feature adds to their versatility, making them suitable for a wide range of tasks.
What is an SDS drill?
SDS refers to ‘Slotted Drive System’ or ‘Special Direct System’, types of fittings for drilling bits that provide a longer life and better hold. SDS drills are usually used for heavy-duty tasks like drilling through concrete or masonry.
What’s the difference between a hammer drill and an impact driver?
While both tools can deliver forceful blows, they serve different purposes. A hammer drill is designed to drill holes into hard materials like concrete or brick, while an impact driver is used primarily to drive screws and bolts.
What does the impact energy mean?
Impact energy, measured in joules (J), describes the power with which a hammer drill can drive into materials. Higher impact energy means the drill can tackle tougher materials and projects.
Can it be used for chiselling?
Some offer a chiselling function. This is often referred to as ‘rotary stop’ or ‘hammer only’ mode, where the rotation function is stopped, and the tool only moves in a forward and backward motion, acting like a mini jackhammer.
When should I use a corded vs. a cordless one?
Choosing between corded and cordless depends on your specific needs. If you require constant power for extended periods and don’t mind being tethered to an outlet, a corded drill is ideal. However, if you value mobility and ease of use over continuous power, cordless models are the way to go.
Are brushless hammer drills better?
Brushless drills are generally more efficient, offering longer runtime, less maintenance, and often more power. However, they tend to be pricier than brushed models. If you’re a casual user or on a budget, a brushed model could be sufficient.
What safety precautions should I take while using ?
Safety measures include wearing protective gear like safety glasses, gloves, and ear protection, securing loose clothing and hair, ensuring your work area is well-lit and free from tripping hazards, and not forcing the drill if it gets stuck.
How do I maintain my hammer drill?
Maintaining your hammer drill is essential to ensure its longevity and optimal performance. Here are some detailed steps to help you keep your tool in the best possible shape.
Regular Cleaning
Just like any other tool, your hammer drill can accumulate dirt and dust during operation. Regularly cleaning it can prevent buildup that could potentially hinder its performance. Pay special attention to the vents and chuck, as these areas tend to accumulate dust. Use a soft brush or compressed air to clean these parts.
Inspect the Cord
For corded hammer drills, it’s vital to periodically check the cord for any signs of damage such as fraying or cuts. If you find any damage, do not attempt to repair it yourself. Instead, take it to a professional to avoid any safety hazards.
Battery Care for Cordless Models
If you’re using a cordless hammer drill, proper battery care is crucial. Always remember to recharge the batteries once they’re low, but avoid overcharging them as it may decrease their lifespan. Also, store the batteries in a cool, dry place when not in use.
Lubricate Moving Parts
Lubricating the moving parts of your drill can help it run more smoothly and reduce wear and tear. Refer to your user manual for specific instructions on how to do this.
Regular Professional Servicing
Even with proper care and maintenance, getting it serviced regularly by a professional is recommended. They can perform a more thorough inspection and address any potential issues early on.
Store Properly
When not in use, store your hammer drill in a clean, dry place. If it came with a case, it’s best to use that for storage. This can protect it from dust and moisture, as well as accidental damage.
