FAQ
What are steel processing knives?
What applications are these knives used for?
Our steel processing knives are used in:
- Steel service centers
- Coil slitting and cut-to-length lines
- Scrap and metal recycling operations
- Plate, sheet, and strip processing
- Heavy-duty industrial cutting applications
What materials are your steel processing knives made from?
Our knives are manufactured from high-quality tool steels and high-alloy steels including grades 1.2379 (D2|SKD11), 1.2343 (H11) & 1.2360 (A8 Mod) selected for strength, wear resistance, and toughness. All knives are CNC-machined and heat-treated to ensure long-term reliability.
Can your knives handle high loads and continuous operation?
Yes. Our steel processing knives are designed for extreme cutting loads, high speeds, and continuous production, ensuring consistent performance and minimal downtime.
What are rubber bonded metal spacers?
Rubber bonded metal spacers are precision components used in slitting lines to maintain accurate spacing between knives while absorbing vibration and reducing noise during operation.
What are the benefits of using rubber bonded metal spacers?
- Improved strip width accuracy
- Vibration and noise reduction
- Protection of knives and shafts
- Enhanced surface finish of slit material
- Longer tool and machine life
Where are rubber bonded metal spacers used?
They are primarily used in:
- Coil slitting lines
- Steel and metal processing lines
- High-speed cutting and slitting applications
Are your products compatible with European, USA and Latin American machines?
Yes. We supply OEM-compatible replacement knives for machines commonly used across Europe, North America and Latin America, as well as custom knives manufactured to customer specifications.
Do you offer custom slitting line tooling?
Yes. We offer custom slitting line tooling based on:
- Machine make and model
- Material thickness and grade
- Required edge geometry and tolerances
What are the advantages of using Industrial SharpCut steel processing knives & slitting tooling?
- Clean and precise cuts

Installation, Maintenance & Safety – Steel Processing Knives & Spacers
Installation
- Lock out and secure the machine before installation
- Clean shafts, knife seats, and spacer surfaces thoroughly
- Install knives and spacers in the correct sequence and orientation
- Use OEM-recommended tightening torque and fasteners
- Ensure correct knife spacing and alignment
Maintenance
- Inspect knives regularly for edge wear, chipping, or cracks
- Check spacers for rubber damage, wear, or loss of bonding
- Maintain proper knife clearances for clean cutting
- Sharpen knives using correct angles and controlled cooling
- Replace worn knives and spacers in matched sets
Safety & Usage Precautions
- Always wear appropriate PPE
- Handle knives carefully—edges are extremely sharp
- Never operate with damaged knives or spacers
- Avoid metal contamination and excessive overload
- Stop the machine immediately if vibration or noise increases
Key Benefits of Proper Handling
- Improved cutting accuracy
- Extended tool and spacer life
- Reduced downtime
- Safer and more stable operation
