Regular Drill vs Hammer Drill vs Rotary Hammer: Complete Comparison
Introduction: Why You Need to Understand the Differences Between Drill Types
Walk into any hardware store in Jordan and ask for a "drill," and the salesperson will immediately ask: do you want a regular drill, a hammer drill, or a rotary hammer? This is where confusion begins for many people, especially those without extensive experience with drilling tools. The truth is that each of these three tools is designed for a different purpose, and choosing the wrong one can cost you time, effort, and money without achieving the desired result.
In this comprehensive guide, we will explain in detail the differences between the Regular Drill (Drill Driver), the Hammer Drill, and the Rotary Hammer, and help you choose the right tool for your work whether you are a hobbyist or a professional.
First: The Regular Drill (Drill Driver)
How It Works
The regular drill is the simplest type of drilling tool, operating with a simple rotation mechanism only. The electric motor spins the drill bit at high speed without any hammering or additional vibration. This mechanism is ideal for soft and medium-hard materials such as wood, plastic, and thin metals.
Typical Technical Specifications
- Power: 400 to 800 watts for corded models
- Speed: 0 to 3,000 RPM
- Chuck Size: Usually 10mm or 13mm
- Weight: Approximately 1.2 to 2 kg
- Voltage (cordless): 12V to 20V
Suitable Applications
- Drilling all types of wood (natural, MDF, particle board)
- Drilling thin metals such as aluminum and light steel
- Driving and removing screws (driver function)
- Home assembly and installation work
- Drilling plastic, drywall, and soft materials

Second: The Hammer Drill
How It Works
The hammer drill combines rotational motion with a hammering (pulsing) action simultaneously. Its hammering mechanism relies on two ribbed cam discs (cam-action) that rotate against each other, generating rapid vibration that converts the rotational motion into rotation plus light hammering. This mechanism allows the hammer drill to drill through light concrete, bricks, and concrete blocks in addition to all materials that a regular drill can handle.
Important Note: The hammering action in a hammer drill is relatively weak compared to a rotary hammer and depends on the pressure you apply to the tool during operation.
Typical Technical Specifications
- Power: 600 to 1,100 watts
- Speed: 0 to 3,000 RPM
- Impact Rate: 0 to 48,000 BPM (Blows Per Minute)
- Impact Energy: Approximately 1.5 to 4 joules
- Chuck Size: Usually 13mm
- Weight: 1.8 to 3 kg
Suitable Applications
- Drilling light to medium concrete (diameters up to 16mm)
- Drilling bricks and concrete blocks
- Drilling natural stone at small diameters
- All regular drill applications (wood, metal, screws)
- General home maintenance and wall-mounted installations

- Stanley STDH8013: A reliable option at 800W with a mid-range price.
Third: The Rotary Hammer (SDS Hammer)
How It Works
The rotary hammer is the most powerful of the three and uses a completely different mechanism than the hammer drill. It relies on an electro-pneumatic mechanism that generates very high impact force without requiring you to press hard on the tool. Compressed air inside the cylinder transfers energy to the bit with high efficiency, which is what makes the rotary hammer capable of drilling through the hardest reinforced concrete with ease.
Most rotary hammer units use the SDS Plus or SDS Max system instead of a regular chuck, and this system allows for quick bit changes and ensures better stability during operation.
Operating Modes
Most rotary hammers provide three operating modes:
- Rotation Only: For drilling in wood and metals using a chuck adapter.
- Rotation + Hammering: For drilling concrete and stone.
- Hammering Only (Chisel Mode): For light demolition, tile removal, and chiseling work.
Typical Technical Specifications
- Power: 750 to 1,500 watts (large models up to 2,000 watts)
- Impact Energy: 2.4 to 12 joules (much stronger than hammer drills)
- Impact Rate: 0 to 5,000 BPM
- Maximum Concrete Drilling Diameter: 26mm to 52mm (depending on model)
- Bit System: SDS Plus (for diameters up to 32mm) or SDS Max (for larger diameters)
- Weight: 2.5 to 7 kg (heavier than the other two types)
Suitable Applications
- Drilling reinforced concrete at large diameters
- Drilling rocks and hard stones
- Installing HVAC systems and pipes in concrete buildings
- Electrical conduit work in concrete walls
- Light demolition and tile removal
- Making openings for plumbing installations
- Construction and contracting projects

Important Tips When Using Drilling Tools
Safety Tips
- Always wear safety glasses: Concrete and metal fragments can cause serious eye injuries.
- Use ear plugs: Especially with the rotary hammer, which produces noise exceeding 90 decibels.
- Wear a dust mask: Concrete and silica dust is very harmful to lungs over the long term.
- Secure the workpiece: Especially when drilling with a regular drill on metals or wood.
- Do not apply excessive pressure: The rotary hammer works efficiently with light pressure; excessive force causes tool damage.
- Check for electrical wires or water pipes: Before drilling into any wall, use a wire and metal detector.
Tips for Extending Tool Life
- Use the appropriate bit: Carbide-tipped bits for concrete, HSS bits for metal, and wood bits for wood.
- Do not overload the tool: A regular drill is not designed for concrete; using it on concrete will burn out the motor.
- Clean the tool after each use: Concrete dust accumulates and causes gear and bearing damage.
- Regularly grease the rotary hammer nose: Apply a small amount of grease to the end of the SDS bit before inserting it.
- Store the tool in a dry place: Moisture causes rust on internal parts and damage to electrical circuits.
Tips for Drilling in Concrete
- Start slowly: Begin at low speed to create a pilot hole that prevents the bit from slipping.
- Withdraw the bit periodically: This helps remove dust from the hole and prevents bit clogging.
- Use water when drilling at large diameters: Water cooling extends bit life and improves hole quality.
- Set the required depth: Use the depth stop included with the tool or place tape on the bit as a marker.
Bit and Accessory Prices in the Jordanian Market
It is also important to know that the cost of bits and accessories varies by tool type:
- Regular drill bits (HSS and wood): 0.5 to 5 JOD per piece depending on diameter and quality.
- Hammer drill bits (standard carbide): 1 to 8 JOD depending on diameter.
- SDS Plus bits for rotary hammers: 2 to 15 JOD depending on diameter and length.
