Portable rebar cutters needs to use a hard, abrasive and heat resistance materials made of blades to meet the requirements of high-strength steel cutting. According to the characteristics of industrial applications and materials, common blade materials and their characteristics are as follows:
1.High-Speed Steel (HSS)
Features: High hardness (HRC60-65), high abrasion resistance, up to 600°C heat resistance, suitable for medium andhigh speed cutting.
Application Scenarios: Lightweight portable cutters suitable for cutting small diameter steel bar (e.g., Φ6-20mm) or thin wall profile.
Strengths: Low cost, easy to grind, suitable for frequent blade changes.
2.Carbide (Tungsten Carbide)
Features: Highly rigid (HRC85-92), 10 -100 times more abrasive than high-speed steel, up to 800 -1000°C.
Application Scenarios: Professional Portable Cutting Machine for cutting 20-40mm steel or high strength alloy steel.
Advantages: long service life, high cutting efficiency, reduce downtime of changing knife.
3. Ceramic Alloys
Features: Hardness second only to diamond, heat resistance over 1000 ℃, excellent chemical stability.
Application Scenarios: High-end portable cutting machine for cutting high hardness materials (such as quenched steel, abrasionresistant cast iron).
Advantages: high precision of cutting surface, fewer burrs, suitable for precision machining needs.
4. Composite Materials (such as diamond coatings)
Features: surface coated with diamond particles, extremely hardness, wear resistance.
Application Scenarios: Special needs scenarios (e.g. steel cutting in reinforced concrete).
Advantages: Extremely long service life, but high cost, suitable for a few professional users.+
