Guillotine Shear Blades
All of this is designed to provide you with the exact blade for your hydraulic shears and cutting applications. Receive more tonnage from the edge while reducing downtime due to blade changes, you will be very pleased with the value for money and recognise the value of our guillotine shear blades.
Features
Guillotine Shear Blades for Metal Sheet Cutting
Our guillotine shear blades deliver consistent, high-precision cuts for carbon steel, stainless steel, aluminum, and galvanized sheets. We manufacture replacement blades for leading guillotine shear brands and support full OEM and reverse-engineering services for global metalworking operations.
Guillotine shears demand blades that stay sharp, resist deformation, and maintain edge alignment through heavy production cycles.
We design every blade with controlled hardness, stable microstructure, and optimized heat-treatment to ensure:
- Clean, burr-free cutting edges
- Reduced cutting force and machine strain
- Longer service life
- Stable performance under continuous operations
Whether you run a small fabrication shop or a high-volume steel service center, our blades maintain reliable repeatability.

Brand Usage Disclaimer (Non-Infringement Notice)
All brand and machine names listed above are used only to identify compatibility and replacement purposes. SHJ KNIFE is not affiliated with the original manufacturers. We produce high-quality aftermarket replacement shear blades, not genuine OEM parts.
OEM & Reverse-Engineering Capabilities
We support full OEM manufacturing for distributors, machine builders, and industrial service companies.
Our engineering team can produce:
- Custom sizes and geometries
- Single- and double-bevel blades
- Standard and segmented guillotine blades
- Blades for mild steel, stainless steel, and high-strength alloys
- Custom hole spacing and slot positions
- Inch or metric specifications
Reverse-Engineering Service Includes:
- Dimensional scanning
- Material analysis
- Hardness and microstructure matching
- Reproduction of complex knife profiles
- Improved wear-resistant upgrades (optional)
You can send us a sample blade, drawing, or even a damaged part-we will rebuild it.
Metal Shear Blades Material & Specifications
We select steel grades and specifications based on your cutting force, production volume, and metal characteristics. This ensures your blade resists wear, holds an edge, and stays structurally stable.
Available Tool Steel Grades
We use tool steels known for strength, toughness, and wear resistance:
D2 / SKD11 – general shearing with high wear resistance
Cr12MoV – stable hardness for most sheet metal applications
H13 – strong toughness for high-impact shearing
6CrW2Si – ideal for long production runs
High-carbon high-chromium steels
Tungsten alloy tool steels (optional for extreme workloads)
Hardness Range
We tune hardness to fit each application:
HRC 50–55 – for impact-heavy cutting
HRC 56–60 – for general sheet metal work
HRC 60–65 – for thin sheet or light-duty precision cutting

We list only a portion of the available blade sizes here because the full range includes many variations. If you need a different size or a custom specification, we can produce it according to your requirements.
Custom Metal Shear Replacement Blades
When customers struggle to find blades for rare or discontinued machines, we step in with flexible custom manufacturing. You can send us a drawing, a dimension list, or even a dull blade. We measure the critical points, reproduce the shape, and improve the steel selection if your cutting workload requires a stronger blade.
Customers who manage multiple machines often choose us to help unify their blade specifications. This reduces sourcing complexity and cuts long-term replacement costs.
Steel Grades for Guillotine Shear Blades
We choose materials based on your cutting environment, production volume, and sheet thickness.
Common Steel Grades We Supply
| Application | Recommended Materials | Benefits |
|---|---|---|
| General carbon steel cutting | 9CrSi / D2 / SKD11 | Strong wear resistance, stable cutting edge |
| High-volume steel service centers | Cr12MoV / Cr12Mo1V1 | Long life, balanced toughness |
| Stainless steel & high-strength alloys | H13 / SKD61 | Heat resistance and impact strength |
| Light-duty & thin sheet | 6CrW2Si | Stable hardness, cost-effective |
We tailor hardness range to: HRC 54–62 depending on sheet type and cutting load.
