When shopping for power tools, the terms “hammer drill” and “regular drill” often cause confusion. While they may look similar, these tools serve very different purposes. Let’s break down their key differences to help you choose the right one for your project.
1. How They Work
Regular Drill (Drill/Driver):
- Operates using rotational force (spinning the drill bit).
- Designed for drilling holes in materials like wood, metal, plastic, or drywall, and driving screws.
- Most models include adjustable clutch settings to prevent overdriving screws.
Hammer Drill:
- Combines rotation with a pulsating hammering action (rapid forward blows).
- The hammering motion helps break through hard, brittle materials like concrete, brick, or masonry.
- Often includes a mode selector to switch between “drilling only” (like a regular drill) and “hammer drill” modes.
2. Key Design Differences
- Mechanism:
- Regular drills rely solely on a motor to spin the chuck and bit.
- Hammer drills have an internal hammer mechanism (often a set of gears or a piston) that creates the pounding motion.
- Chuck and Bits:
- Regular drills use standard twist bits, spade bits, or driver bits.
- Hammer drills require masonry bits (carbide-tipped) designed to withstand impact. Some models use SDS-Plus or SDS-Max chucks for better impact transfer.
- Weight and Size:
- Hammer drills are typically heavier and bulkier due to their hammering components.
3. When to Use Each Tool
Use a Regular Drill If You’re:
- Drilling into wood, metal, plastic, or drywall.
- Driving screws, assembling furniture, or hanging lightweight shelves.
- Working on precision tasks where control is critical.
Use a Hammer Drill If You’re:
- Drilling into concrete, brick, stone, or masonry.
- Installing anchors, bolts, or wall plugs in hard surfaces.
- Tackling outdoor projects like securing deck posts into concrete footings.
4. Power and Performance
- Speed (RPM):
Regular drills often have higher RPMs for smoother drilling in softer materials. - Impact Rate (BPM):
Hammer drills measure blows per minute (BPM), typically ranging from 20,000 to 50,000 BPM, to power through tough surfaces.
Pro Tip: Using a regular drill on concrete will overheat the bit and damage the tool. Always match the tool to the material!
5. Price Comparison
- Regular Drills: Generally cheaper (starting around $50 for cordless models).
- Hammer Drills: More expensive due to their complex mechanisms (often $100+ for cordless versions).
What About Impact Drivers?
Don’t confuse hammer drills with impact drivers, which are designed for driving screws and bolts:
- Impact drivers deliver high rotational torque (twisting force) but lack hammering action.
- They’re ideal for heavy-duty fastening, not drilling into hard materials.
Can a Hammer Drill Replace a Regular Drill?
Yes—but with caveats:
- In “drill-only” mode, a hammer drill can handle tasks like a regular drill.
- However, hammer drills are heavier and less comfortable for prolonged use on soft materials.
For most DIYers: Owning both a regular drill and a hammer drill (or a combo kit) is ideal for versatility.
Final Verdict
- Regular Drill: Your go-to for everyday drilling and driving in wood, metal, or plastic.
- Hammer Drill: A specialized tool for conquering concrete, brick, and masonry.
By understanding these differences, you’ll save time, avoid tool damage, and achieve cleaner results on any project!
