A combi drill is a versatile power tool that combines the functions of a standard drill driver with an additional hammering action, making it suitable for a wider range of tasks.
Often referred to as a 3-in-1 tool, the combi drill incorporates the capabilities of a drill driver for drilling into materials like wood, metal, and plastic, as well as screwdriving. What sets it apart is the additional hammer-action feature. As stated in the reference, combi drills "offer all the same features as a drill driver, but with the additional hammer-action feature, making it suitable for drilling into masonry and brick too".
Core Functions of a Combi Drill
A combi drill typically operates in three distinct modes:
- Screwdriving Mode: Functions like an electric screwdriver, applying torque to drive or remove screws. It usually includes adjustable clutch settings to prevent overtightening.
- Drilling Mode: Performs standard rotary drilling for creating holes in softer materials such as wood, plastic, and metal.
- Hammer Drilling Mode: Engages the hammer mechanism, which creates rapid, forward-and-backward pulsing motions of the drill bit while it rotates. This percussive action breaks up hard materials like concrete, brick, and stone, allowing the drill bit to penetrate more effectively.
Why Choose a Combi Drill?
Combi drills are popular for their versatility, especially for DIY enthusiasts and tradespeople who work with various materials. Because these 3-in-1 drills make them a great all rounder, you can often tackle multiple jobs with just one tool, saving space and cost compared to buying separate tools for each function.
- Versatility: Handles screwdriving, standard drilling, and hammer drilling.
- Efficiency: Drills through hard materials faster than a standard drill.
- Convenience: Reduces the need for multiple tools for different tasks.
Combi Drill vs. Drill Driver
Understanding the key difference is crucial:
| Feature | Drill Driver | Combi Drill |
|---|---|---|
| Screwdriving | Yes | Yes |
| Standard Drilling | Yes (Wood, Metal, Plastic) | Yes (Wood, Metal, Plastic) |
| Hammer Action | No | Yes |
| Suitable for Masonry/Brick | Limited / Not Recommended | Yes |
In essence, a combi drill adds the hammer capability to a standard drill driver, significantly increasing the range of materials it can effectively drill into.
