There are many kinds of helical steel cutting tools, which can be divided into the following kinds according to operation method, power supply and usage scenario:
1.Electric Cutting Tools
Rebar Cutters
Desktop models: equipped with grinding wheel or alloy saw blade, can cut steel bar up to 35mm in diameter, suitable for batch work on construction sites.
Handheld cold cut saw: brushless motor technology, sparkless, low noise cutting, suitable for indoor or precision applications.
Metal belt saw: automatic feeding and cutting of steel bundles up to 20 pieces per minute, suitable for large steel fabrication plants.
Multi-purpose profile cutter: through the replacement of saw blade, can cut wood, aluminum and other materials to meet diverse construction needs.
Wall Cutting Machine: Using diamond chain to cut through reinforced concrete walls to create a 35cm deep trench for doors and windows.
2.Manual Cutting Tools
Manual Rebar Shears
Hydraulic models: lever pressurized, can cut up to 22mm diameter steel bar, suitable for fire protection and outdoor work. Mechanical: Forged of manganese steel, with a jaw hard enough to reach HRC55, the steel bar can be cut to a diameter of up to 16mm, suitable for home repairs.
Bolt Cutter Series: Specially designed to cut cables and wires, with a jaw length of between 200mm and 1000mm. Some models come with 10kV insulation.
III. Professional Cutting Tools: fire emergency tools: including handheld rebar cutters and non-electric cutting machine. Using high-strength alloy blades, they can cut steel to 25mm in diameter in 5 seconds. They are useful for earthquake rescue or accident relief.
Portable Hydraulic Equipment: including portable electric hydraulic rebar cutters, weighing only 8kg, can be operated with one hand, cutting steel bar diameter up to 16mm. They work well on high or in enclosed spaces.
Angle Grinder Conversion Kit: By installing a brazed diamond blade, you can convert a regular angle grinder into a a rebar cutter. This is a low-cost option, but requires professional handling.
3. INTRODUCTION Cutting method classification: sawing: cold-cut saw adopts alloy blades, high cutting precision, suitable for precision machining. Hot Saws: These cut corrugated steel at high temperatures, resulting in quick cuts but sparks. Fire safety measures are therefore required.
Shearing
Hydraulic Shears: This type of shears is pressurized by hydraulic system and can cut steel bar more than 32mm in diameter, suitable for heavy duty operation.
Mechanical shears: use lever mechanism, suitable for steel bar cutting up to 16mm diameter, with high portability.
Grinding
Angle grinders: They use diamond blades to cut steel bars, but are less efficient and suitable for small-scale operations.
V. By Use Scenario
Construction site: It is recommended benchtop rebar cutters or metal band saws, high efficiency, suitable for large-scale operation.
Home Repairs: choose manual rebar cutters or small hydraulic cutting machine, lightweight, economical.
Fire and Rescue: Handheld steel or non-electric cutting machines are used to ensure rapid response and safety.
High-altitude operation: the use of portable hydraulic rebar cutters, lightweight, flexible operation.
