- The keyed chuck requires an extra step for bit changes compared to keyless models
- Not designed for hammer drilling in reinforced concrete - intended for dry core and standard drilling
- Requires access to 240V power - not a cordless option
Best Use Cases
- Drilling large-diameter holes in bricks or soft masonry using dry core bits
- Installing plumbing pipes, electrical conduits, or ventilation systems in building projects

Frequently Asked Questions
Q: What size core bits can I use with the Dewalt D21570K?
A: This drill driver can accommodate dry core bits up to 127mm diameter for use on bricks and soft masonry. It's not intended for wet core drilling or reinforced concrete, but it handles large-diameter dry core tasks efficiently.
Q: Does it come with a case or any accessories?
A: Yes, the D21570K is supplied with a sturdy carrying case, a multi-position side handle for better control, and a depth stop for precision drilling. These accessories help with setup and safe transport.
Q: Is this drill suitable for reinforced concrete work?
A: This tool is primarily designed for dry core drilling in brick and soft masonry, as well as standard drilling in wood and metal. For heavy-duty reinforced concrete, a hammer drill or rotary hammer may be more suitable, depending on bit size and task.
Q: What type of chuck does it have, and why is that important?
A: It features a heavy-duty 16mm keyed steel chuck. While this offers excellent grip for larger bits and core accessories, changing bits is slightly slower compared to keyless chucks. However, the secure fit is valuable for demanding applications.
Q: Can the speed be adjusted for different materials?
A: Absolutely - the two-speed gearbox and variable trigger allow you to match speed and torque to your material. Lower speeds are ideal for large core bits and harder materials, while higher speeds are suitable for smaller bits and softer materials.
Q: Is this tool difficult to handle given its weight?
A: At around 3kg, it is heavier than typical DIY drills, but that weight helps provide stability during core drilling. It's well balanced and includes a multi-position side handle, which many users find helpful for control, especially in repetitive or awkward positions.
