Industrial Rebar Cutting Blocks for Portable Electric Cutters

Industrial Rebar Cutting Blocks for Portable Electric Cutters

1. Blade Material Selection

• H13 Material: The most popular high-quality blade. It is very wear-resistant and tough, with great heat resistance. No deformation or chipping during long, heavy cutting. Perfect for high-strength rebar.

• Cr12MoV Material: Hard and wear-resistant (harder than regular alloy blades). Good for cutting hard cold-rolled rebar. Note: It is less tough—avoid high-impact or large-gap cutting.

• 9CrSi Material: Cheap and practical. Easy to harden and machine. Good for regular medium-low strength rebar, widely used in small and medium projects.

2. Machine Specification Matching (Custom Sizes)

2.1 Shape Matching

• Square blades: 4 usable edges. Rotate them to last longer (good for large-scale work).

• Rectangular blades: 1 or 2 edges. Good for small-tonnage cutters.

2.2 Size Matching

3. Best for Different Rebar Types

• Ordinary Round Steel: Low hardness and cutting resistance. Use 9CrSi or Cr12MoV (saves cost).

• High-Strength Ribbed Rebar: Hard, with ribbed surfaces that wear blades. Use H13 (wear-resistant, tough, reduces chipping).

• Scrap Rebar: Corroded, with sand/dirt that wears blades. Use high-nickel materials.

4. Manufacturing Process

5. Custom Rebar Cutting Blocks

• We optimize hardening depth and toughness to fix the common problem of brittle fracture when cutting high-strength rebar.

• H13 blades: Very wear-resistant and stable. No deformation or chipping during long heavy cutting. Ideal for international trade (fewer replacements = lower transport and customs costs).

6. Extend Blade Life

• Correct Alignment: Make sure cutting blocks are firmly placed in the machine.

• Regular Rotation: Most blocks have 4 edges—rotate them to keep performance high.

• Clearance Check: Keep blade gaps adjusted to the manufacturer’s standards.
