Sheet Metal Shear Blades
No matter what material you need to cut, Shungji can provide the right bevel and alloy of knife design you need to get the job done. We offer hundreds of different cutter designs to meet our customers' needs.
Features
Sheet Metal Shear Blades
for Light to Medium Gauge Cutting
Our sheet metal shear blades deliver clean, accurate cuts for light and medium gauge materials. These blades suit fabrication shops, HVAC manufacturers, metal enclosure producers, and coil processing lines that need consistent performance without the heavy-force requirements of hydraulic shearing.
At SHJ KNIFE, we engineer each blade to match your material thickness, cutting speed, and production cycle, helping you keep your workflow smooth and efficient.
Replacement Shear Blades for Shearing Machine Brands
We manufacture replacement shear blades that fit more than forty major shearing machine brands commonly used across the metalworking industry, including:

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
Right after confirming machine compatibility, many customers choose SHJ KNIFE because they need OEM-level replacement work, especially when the original manufacturer no longer supplies parts. We support:
- OEM production for machinery manufacturers
- Reverse engineering from a worn blade sample
- Custom builds when drawings are missing
- Legacy blade reproduction for discontinued machines
Our engineering team rebuilds precise measurements and improves performance by selecting stronger tool steels or upgraded heat treatment profiles. This allows us to deliver reliable blades even when machines are decades old.
We offer blade solutions tailored to the specifications of each machine, including custom dimensions and mounting configurations. If you require a replacement for a specific resurfacer model, our engineering team can assist in matching the right blade for your setup.
*Disclaimer: We are not affiliated with or endorsed by any of the brand names listed above. All references are for compatibility purposes only.
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

Why Sheet Metal Requires a Different Shear Blade Design
The blade must keep a sharp edge, maintain flatness, and cut smooth lines without burrs. Unlike heavy-duty shearing, sheet metal cutting focuses on speed, edge quality, and reduced wear. Effective sheet metal shear blades provide:
- High edge sharpness
- Stable cutting geometry
- Low friction during fast cutting
- Tight dimensional accuracy
- Clean edges for downstream forming or bending
This balance makes your production more efficient and extends both blade life and machine life.
FAQ - Sheet Metal Shear Blades
Q1. What makes sheet metal shear blades different from heavy-duty blades?
They focus on edge sharpness and cutting smoothness rather than extreme toughness.
Q2. Can you customize blade thickness or bevel angles?
Yes. We design the blade geometry to match your sheet thickness and required cut quality.
Q3. Do you support OEM replacement blades for sheet metal lines?
Yes. We manufacture blades that match or exceed OEM standards.
Q4. Which steel grade is best for continuous coil cutting?
D2 usually performs best due to its wear resistance.
Q5. Can you produce blades for older sheet metal shears?
Yes. We reverse-engineer blades from worn samples.
