Ironworker Notcher Blades

Achieving Perfect Corner Cuts: The Ultimate Guide to Ironworker Notcher Blades

What Are Ironworker Notcher Blades?

• Notching (corner/notch cutting) is key before welding and assembly

• Blade quality directly affects cut neatness

• Worn blades cause burrs and extra pressure on the machine’s hydraulic pump

• Important hydraulic ironworker parts and ironworker tooling accessories

• Similar to shear blades: core wear parts for ironworker machines

• Used for cold cutting metal (angle steel, flat steel, etc.)

• Used in steel factories, construction sites and metal shops

• Material, heat treatment and precision affect efficiency, quality and service life

1. Common Notching Styles

• 90° V-Notcher: Most common; used for bending angle steel/plates

• Rectangular Notcher: Cuts rectangular notches for nested assembly

• Flat Bar Coper: For flat steel edges; coper notcher replacement available

2. Material Advantages: Choose Cr12MoV or H13

Cr12MoV Blades (Most Popular)

• Hardness: HRC 58-62 (after special heat treatment)

• Pros: Good for cold cutting, durable, not easy to break

• Best for: Medium/heavy, frequent cutting; regular metal profiles; mass production

• Fits: 90% of medium/heavy ironworker machines

H13 Blades (For Tough Conditions)

• Hardness: HRC 52-55 (after heat treatment)

• Pros: Very tough, no easy breaking; works with dirty/imperfect metal

• Best for: Heavy cutting; large metal (≥100mm); high-strength steel

• Fits: Custom heavy-duty ironworker machines

Other Material & Processing Pros

• High-Chrome Tool Steel (D2): Balances hardness and toughness well

• Precision Grinding: Blades fit perfectly (positive/negative clearance)

• Stable Hardness: No easy chipping or fast wear

3. Key Blade Performance Needs

• Stable hardness (not too hard or too soft)

• Strong toughness (no breaking/deformation when cutting)

• Wear-resistant (stays sharp for frequent use)

4. Compatibility: Easy Blade Replacement

• Standard corner shearing blades for major brands: Piranha / Geka / Sunrise / Edwards / Mubea (ready to install)

• Custom blades: 1:1 made from your old blade (drawings or sample) for non-standard machines
