Daewoo Rotary Drill 26MM

A rotary hammer drill, often simply referred to as a rotary hammer, is a powerful tool designed for drilling into tough materials like concrete, stone, and masonry. It is widely used in construction and renovation projects where standard drills might struggle due to the hardness of the materials being drilled. Rotary hammer drills are known for their ability to provide impact force along with rotational motion, making them effective for heavy-duty drilling tasks.

Key features and characteristics of rotary hammer drills include:

1. Hammering Action: Unlike regular drills that simply rotate, rotary hammer drills combine rotation with a hammering or percussion action. This hammering motion delivers rapid impacts to the drill bit, helping to break through tough surfaces.

2. Drilling Power: Rotary hammers are designed to handle demanding drilling tasks. They can bore holes in concrete, brick, stone, and other hard materials more effectively than standard drills.

3. Chuck Types: Rotary hammers typically have SDS (Slotted Drive System) chucks, which are quick and easy to swap out. The SDS system ensures a secure grip on the drill bit while accommodating the high forces generated during drilling.

4. Modes: Many rotary hammers offer multiple operating modes, including rotation-only mode for standard drilling, hammer-only mode for chiseling or breaking tasks, and a combination of rotation and hammering for drilling into hard materials.

5. Power Sources: Rotary hammer drills can be powered by electricity or batteries. Corded electric models provide continuous power, while cordless models offer more portability but might have limitations on runtime.

6. Attachments: Some rotary hammer drills can be equipped with various attachments, such as chisels and points, for tasks like chiseling, scaling, and removing materials.

7. Size and Weight: Rotary hammers come in different sizes, ranging from compact models suitable for light tasks to larger, more powerful ones for heavy-duty applications.

8. Vibration Control: High-powered rotary hammer drills can produce significant vibrations during operation. Some models include features to minimize vibration, making them more comfortable to use for longer periods.

Common uses for rotary hammer drills include:

• Drilling holes for anchors and fasteners in concrete and masonry.
• Installing electrical conduits or pipes in walls made of hard materials.
• Chiseling and breaking concrete for demolition or renovation projects.
• Creating openings for doors and windows in concrete walls.

When using a rotary hammer drill, it's important to follow safety guidelines, wear appropriate protective gear, and select the appropriate drill bit and mode for the task at hand. Proper technique and safety precautions will ensure efficient and safe drilling operations.
