The SDS Plus Hammer Drill is a highly efficient tool in construction, renovation, stone processing, and even metal drilling. It is widely used for drilling into hard materials such as concrete, brick walls, and tiles. Compared with ordinary impact drills, it delivers stronger impact force and higher efficiency, making it an essential device for both professional construction and home improvement. This article will provide a detailed overview of the uses of hammer drills, their differences from standard impact drills, the influence of power, comparisons between cordless and corded versions, drilling depth, maintenance, and common issues to help users better choose and operate this tool.
The hammer drill is specifically designed for drilling into high-hardness materials, with common applications including:
Concrete Drilling: For installing expansion bolts, anchor bolts, etc.
Brick Wall Drilling: Suitable for red bricks, hollow bricks, and other masonry structures.
Tile/Stone Drilling: For installing brackets, hooks, etc., with the help of special drill bits.
Metal Drilling: Can be used with alloy drill bits for metal processing (though less efficient than specialized metal drills).
Its unique SDS Plus quick-change chuck system allows for easier bit replacement while providing stronger impact force, making it ideal for long-term, high-intensity operations.
Comparison Item | SDS Plus Hammer Drill | Standard Impact Drill |
Impact Mechanism | Cylinder piston impact, stronger force | Gear impact, weaker force |
Suitable Materials | Concrete, stone, hard bricks | Wood, soft bricks, lightweight concrete |
Drilling Efficiency | Fast, suitable for deep and large holes | Slower, suitable for small and shallow holes |
Chuck Type | SDS Plus quick-change system | Traditional three-jaw chuck |
Price | Higher | Lower |
Conclusion:
If you frequently drill into concrete or stone, the hammer drill is a more efficient choice.
Standard impact drills are more suitable for light-duty work, such as wood, plastic, and thin metal sheets.
The power rating of a hammer drill directly affects its drilling capacity and efficiency:
500W–800W: Suitable for home use, can drill holes with a diameter of 8–12mm.
800W–1200W: Commercial grade, capable of drilling 12–20mm holes, ideal for heavy-duty work.
1200W and above: Industrial grade, capable of drilling over 25mm deep holes, such as in reinforced concrete foundations.
Recommended Power Selection:
Home renovation: 700W–900W
Construction site work: 1000W and above
Cordless version: Choose models with 20V or higher voltage to ensure sufficient power
Version | dvantages | Disadvantages |
Cordless | Portable, ideal for high-altitude or no-power environments | Limited battery life, high-power models are more expensive |
Corded | Stable power, suitable for long-duration work | Restricted by power source, less convenient mobility |
How to Choose?
If you need frequent mobility or outdoor work → Cordless version
For long-term operation at fixed locations → Corded version
The drilling depth depends on the drill's power, bit type, and material hardness:
Concrete: Typically 10–30 cm (diameter ≤20mm).
Brick walls: Up to 30–50 cm (sectional drilling recommended to avoid overheating).
Tiles: Use a glass/tile drill bit, depth ≤5 cm to prevent cracking.
Deep drilling tips:
1.Drill in sections, withdraw every 5 cm to clear debris.
2.Use extended drill bits and maintain vertical feed.
1.Press the chuck lock and pull out the old bit.
2.Insert the new bit, ensuring the slots are aligned.
3.Rotate the bit until it clicks into place, indicating it is securely locked.
Note: Do not force the bit in if not aligned properly, as this may damage the chuck.
1.Use glass/tile-specific drill bits to avoid cracking.
2.Start at low speed; once the bit is positioned, gradually increase speed.
3.Apply water cooling to reduce edge chipping risk.
1. Service Life
Under normal use, it can last 5–8 years. Key components (such as motor and bearings) should be inspected regularly.
2. Cleaning and Care
After each use: blow off dust with an air gun, check drill bit wear.
For long-term storage: keep in a dry environment, store batteries at around 50% charge.
3. Lubrication
Every 3 months, add special lubricant to the cylinder and bearings to reduce wear.
4. Drill Bit Wear and Repair
Minor wear: sharpen the edge with a grinding wheel.
Severe wear: replacement is recommended.
5. Causes of Drill Jamming & Solutions
Causes: dull bit, excessive feed speed, debris blockage.
Solutions: withdraw the bit to clear debris, replace with a sharp bit.
Protective gear is essential: Wear safety goggles, dust mask, and gloves.
Storage methods:
Store batteries separately, avoid high temperature and humidity.
Apply anti-rust oil to drill bits to prevent oxidation.
1.High drilling efficiency: More than 3 times faster than ordinary impact drills.
2.Durability: Suitable for long-term, high-intensity operations.
3.Versatility: Compatible with different drill bits for a variety of materials.
