The blade has a larger diameter to enable it to cut through concrete surfaces easily. During the cutting process, the saw will manufacture large kerfs, which are the spaces that gaps left from cut materials.
  • Horsepower: The horsepower (HP) of a concrete power cutter indicates the capacity and amount of power the tool can generate to cut through tough concrete surfaces. The horsepower of a concrete cutter is typically between 4 and 8.5 in gas-powered cutters. Some models can even go higher. Electric cutters have different horsepower depending on whether it's corded or wall-mounted. For corded cutters, it's between 3 to 5 HP, while wall-mounted is between 5 to 7.5 HP.
  • Weight: The weight of concrete power cutters varies depending on the kind of power source the cutter uses. Gas-powered cutters are bulky due to the engine and the fuel it carries. On average, a gas-powered concrete cutter may weigh between 24 to 30 kg. Electric cutters, on the other hand, are lighter and can weigh between 16 to 20 kg.

Maintenance

Over time, concrete power cutters may need maintenance to keep them functional and effective. Some of the maintenance parts of a concrete power cutter include:

  • Cutting blade: It's easy for a concrete cutter blade to wear out because it cuts through tough surfaces. When this happens, operators need to replace the blade quickly to maintain cutting performance and precision. During operation, if the cutter starts making irregular noises or if it feels stuck in a spot, the problem could be a dull blade. It's also important to regularly inspect the blades for any signs of damage such as cracks or warping. If there's any, it should be replaced immediately to ensure safety for the operators and those around them.
  • Air filter: For gas-powered concrete cutters, the air filter helps to block dust and debris from interfering with the engine's performance. Over time, the air filter gets dirty and dusty, which affects its ability to filter out the bad stuff. This exposes the engine to harmful debris. Hence, changing the air filter regularly will prevent this from happening and keep the cutter operating at peak efficiency.
  • Water pump: Hand-held concrete cutters need water cooling to avoid overheating and also minimize dust from the cutting surface. The role of a water pump in a cutter is to provide adequate water for these two benefits. However, it can get damaged, clogged, or corroded over time. Regularly checking it for any signs of damage and repairing or replacing it can ensure continuous water supply for cutting operations.
