BOSCH GBH 220: Motor and Material Technology
The secrets behind this machine’s long-lasting durability
1. Motor Technology (Copper-Core Motor)
The heart of this machine is its 720W High-Torque motor. It is not made of ordinary aluminum wires.
- 100% Pure Copper Winding: The motor is wound with high-quality copper wires, which reduces power loss and prevents the machine from overheating.
- Resin Coated Armature: The armature is coated with ‘Epoxy Resin’. This acts as a shield, protecting the motor coil from damage caused by dust and cement particles entering during drilling.
- Auto-stop Carbon Brushes: The motor automatically stops when the carbon brushes are worn out. This prevents the coil from burning and extends the overall life of the motor.
2. Gear System (Hardened Alloy Steel Gears)
To withstand the vibrations during concrete demolition, all internal gears are made of Heat-Treated Alloy Steel.
3. Protective Housing (High-Grade Build)
The external structure is designed for two specific purposes:
|
Polyamide Shell: Glass-fiber reinforced polyamide plastic. It withstands impacts and provides Double Insulation to protect against electric shocks. |
Vibration Dampening Rubber: The rubber grip on the handle prevents machine vibrations from transferring to your wrists and hands, allowing for longer working hours. |
4. Heat Management (Ventilation System)
As the Internal Cooling Fan rotates around the motor, it pulls in cool air through the front vents and continuously exhausts heat. This ensures consistent motor performance even during non-stop work.
🏠 Real-World Usage Scenarios
- ⚡ Home Decor: Easily mount photo frames, TV wall mounts, and heavy curtain rods without any struggle.
- ⚡ Kitchen Installation: Drill precise holes in hard concrete for installing kitchen cabinets and chimneys.
- ⚡ Tiling Projects: Use the ‘Chisel Mode’ to effortlessly strip away old bathroom or kitchen tiles.
- ⚡ Electrical Work: Perfect for wall chasing to install concealed wiring and switch boxes.
✅ Key Pros of BOSCH GBH 220
Incredible Speed: Thanks to its 2.0 Joules of impact energy, tasks that take 2 minutes for an ordinary drill can be finished in just 30 seconds.
Fatigue-Free Work: Weighing only 2.3 kg, it prevents shoulder strain even when working overhead or on ceilings for long durations.
Multi-Purpose Utility: Not just for drilling—it can also be used for chiseling, eliminating the need to buy separate machines for different tasks.
Low Vibrations: Bosch’s vibration control technology ensures minimal hand shaking while the machine is in operation, providing better control.
Instant Bit Change: The SDS Plus system allows you to change bits in a second without searching for a chuck key in the middle of your work.
Long-Term Investment: Built with high-quality carbon brushes and a heat-resistant copper motor, it is far more durable and reliable than local brands.
🤔 Who is this for? (Target Audience)
Check if this matches your requirements
👷♂️ Professionals (Pros)
If you are an electrician, plumber, or AC technician, this machine is your best friend. It is 100% capable of handling tough daily tasks like drilling into heavy concrete and wall chasing (chiseling).
🏠 Home Owners
This is an excellent choice for DIY (Do It Yourself) enthusiasts who prefer to handle their own home repairs. While ordinary drill machines struggle with hard pillars or beams, this rotary hammer glides through them like a knife through butter.
🏗️ Small Contractors
For small contractors looking for a branded, durable machine on a budget, this is a solid investment. Its lightweight design makes it very easy for workers to handle throughout the day.
If you only need to make small holes in wood or metal sheets (for example, basic carpentry work), a standard rotary drill machine would be more than enough for your needs.
Quick Comparison: Which one is right for you?
| Features | Standard Impact Drill | BOSCH GBH 220 |
|---|---|---|
| Primary Use | Wood, small wall holes | Concrete, Beams, and Chiseling |
| Hammer Action | Moderate Vibration | True Hammer Blows (Pneumatic) |
| Bit System | Requires Chuck Key | SDS Plus (Keyless) |
| Demolition Feature | Not Available | Available (Chiseling Mode) |
| Working Speed | Slower (Requires pressure) | Very Fast (Effortless) |
⚡ Performance Test
Real-world testing results from the field
1. Concrete and Pillar Test
We tested it on a 4-inch thick concrete beam using a 12mm drill bit.
2. Chiseling and Tile Removal
We tested it with a ‘Flat Chisel’ bit to remove old bathroom tiles.
3. Heat Management (Heat Test)
We checked the machine’s temperature after drilling 15 holes consecutively.
❓ Frequently Asked Questions (FAQs)
1. Are drill bits included for free with this machine?
No, this package usually includes only the machine and the carrying case. You need to purchase bits separately. Keep in mind that it only accepts SDS Plus bits.
2. Is this a battery-operated or corded drill?
This is a Corded Electric model. It runs directly on AC power (plug-in), allowing you to work for hours without worrying about battery life.
3. Can I use bits from my old drill machine in this one?
Standard drill bits have a round shank and will not fit this machine. You must use SDS Plus type bits, which are specifically designed to handle high impact and vibrations without slipping.
4. Can this drill make holes in heavy concrete and stone walls?
Absolutely! Its 2.0 Joules impact energy is specifically engineered to drill effortlessly through tough concrete, pillars, and hard stone.
5. Does this machine require a lot of maintenance?
Not much maintenance is needed. Simply wipe the machine clean after use and store it in its case. You only need to replace the carbon brushes once they wear out, which usually takes a long time.
⚠️ Drawbacks & Who Should Avoid This?
Cons (Disadvantages):
- Bit Cost: Standard drill bits won’t work with this machine. You must use specialized SDS Plus bits, which are slightly more expensive than regular ones.
- Cord Length: The power cord is only about 2 – 3 meters long. You will definitely need an ‘Extension Box’ when working in large rooms or high areas.
- No Bits Included: It is disappointing that even for a premium brand, they don’t include at least a basic 6mm or 8mm bit for free in the box.
- Noise Level: Being a hammer machine, it produces significant noise (around 90-100 dB) during operation.
Who Should Avoid This?
This machine is NOT the right choice for the following requirements:
- Carpenters: If your work primarily involves wood and plywood, this machine might feel too heavy for you. A standard ‘Rotary Drill’ would be more suitable.
- Very Thin Walls: If your house walls are very thin or the plastering is weak, avoid using this. Its powerful ‘Hammering’ force might cause cracks in the wall.
- Budget Concerns: For those who only need to drill a single nail once a year, this high-priced machine is an unnecessary investment.
💡 Professional Tips & Secret Hacks
1. What to do if the bit gets stuck? (The Reverse Hack)
While drilling in concrete, if the bit gets stuck on a rebar (iron rod), do not pull the machine forcefully.
Trick: Turn on the Reverse Switch on the machine and press the trigger very slowly. The bit will come out smoothly without any damage.
2. How to protect the motor? (The No-Pressure Rule)
Many people apply heavy pressure on the machine while drilling. However, you should not do that with a rotary hammer.
Pro Tip: Just hold and guide the machine; do not push it. Let the machine use its own weight and impact energy to drill. Applying extra pressure will overheat the motor and cause the carbon brushes to wear out faster.
3. How to prevent dust from falling?
To prevent dust from falling into your eyes while drilling into a ceiling, make a small hole at the bottom of a Paper Cup and slide it onto the drill bit. All the falling dust will be collected inside the cup!

Final Verdict
The BOSCH GBH 220 is not just an ordinary drilling machine; it is a powerful tool that significantly reduces your workload. While there are many cheap alternatives in the market, for those who believe in “One-time investment, years of service,” there is no better choice than this Bosch rotary hammer.
If you are a professional, it will enhance your efficiency and income. If you are a homeowner, it saves you the time spent waiting for a mechanic or electrician. Although the lack of free drill bits in the box is a slight drawback, the sheer power of the motor and build quality makes it easy to overlook.
