A 110mm rotary hammer (also known as a rotary hammer drill or simply a rotary hammer) is a powerful tool used primarily for heavy-duty drilling and demolition tasks. It is designed to handle tough materials such as concrete, stone, and masonry. The "110" in its name typically refers to the diameter of the drill bit it can accommodate, which is 110mm (approximately 4.33 inches). This tool is commonly used in construction, renovation, and demolition projects.

How It Works:

The rotary hammer combines rotation with a hammering action to break through hard materials. It uses a piston mechanism to deliver rapid, high-impact blows to the drill bit, allowing it to chip away at concrete or stone while simultaneously rotating to drill holes. This dual action makes it far more efficient than standard drills for heavy-duty applications.

Key Features:

  1. Hammering Action: Delivers powerful blows to break through tough materials.

  2. Rotation: Helps drill clean, precise holes.

  3. Chuck System: Uses an SDS (Slotted Drive System) or similar chuck to securely hold drill bits.

  4. Variable Speed: Allows users to adjust the speed and power based on the material being worked on.

  5. Vibration Control: Reduces user fatigue by minimizing vibrations during operation.

Applications:

  • Drilling large holes in concrete, stone, or masonry.

  • Demolition work, such as breaking up concrete slabs or walls.

  • Installing anchors, rebar, or dowels in concrete.

  • Heavy-duty construction tasks.

Advantages:

  • High efficiency in hard materials.

  • Reduces effort and time compared to manual tools.

  • Versatile for both drilling and demolition.

Disadvantages:

  • Heavier and bulkier than standard drills.

  • More expensive due to its specialized function.
