Shear Blades and Slitter Knives
for Metal Processing Lines

Made-to-print or sample-matched knives for sheet, strip, and coil operations—optimized for clearance stability, edge life, and consistent cut quality.

Metal Cutting Is Clearance-Driven

Metal cutting performance depends on controlled shear mechanics. Small differences in clearance, edge geometry, straightness/runout, and hardness/toughness balance can quickly show up as burrs, rollover, edge chipping, and shortened tool life. 

Davion supports metal processing operations with made-to-print blades and knife sets designed to improve:

Operations We Support

Sheet Shearing and Plate Processing

Guillotine shears and chop stations depend on straightness, edge geometry, and controlled clearance. 

Slitting systems are sensitive to runout, stack behavior, and edge condition; set-level consistency is key. 

Dynamic cutting demands stable edges and consistent mounting to maintain cut quality at speed.

Trim knives and rotary shear stations require alignment and edge stability to control burr and edge defects.

Typical Converting Operations We Support​

Metal Cutting Blades

Control Burr, Wear, and Edge Consistency in Metal Cutting

Metal processing demands blades that handle high forces, abrasion, and heat without losing edge integrity. Poor blade selection leads to burr formation, chipping, and inconsistent cut quality. We supply blades matched to your material grade, thickness, and cutting method for stable, repeatable results.

Applications & Variants (Blade Styles & Options)

Guillotine Shear Blades (Upper/Lower Sets)

What it is: Straight shear knives used as a matched set in guillotine shears.

When used: Sheet and plate cutting where straightness and clearance control drive burr and rollover.

Cut-to-Length Shear Blades (Line-Defined)

What it is: Shear blades used in CTL lines to cut strip to precise length.

When used: Coil-fed sheet production where repeat length and edge consistency matter.

Flying Shear Blades (Line-Defined)

What it is: Shear blades designed for synchronized cutting on moving strip.

When used: High-speed lines where stopping the strip is not practical.

Crop Shear Blades (Application-Defined)

What it is: Blades used to crop ends or cut bars/sections in heavy-duty stations.

When used: Where shock loading is higher and edge robustness is critical.

Custom Hole/Slot Pattern Shear Blades

What it is: Blades with machine-specific mounting patterns and datums.

When used: When repeatable installation and alignment are required for cut quality.

Coil Slitter Knives (Top Knives)

What it is: Circular knives used to slit coil into narrower widths.

When used: Coil slitting lines where edge quality and burr control are critical.

Bottom Knives / Slitter Anvils

What it is: Mating knives/anvils that define the slitting interface with top knives.

When used: When stable overlap/clearance is required across a slitter stack.

Matched Slitter Knife Sets + Spacers (Stack Systems)

What it is: Knife/spacer stacks designed for consistent width and engagement.

When used: Multi-lane slitting where lane-to-lane variation causes scrap and rework.

Rotary Shear Knives (Strip Processing)

What it is: Knife pairs that shear continuously as they rotate.

When used: Strip cutting where continuous operation and controlled edge quality are needed.

Trim Knives for Strip Edges

What it is: Knives that remove edge trim to stabilize strip geometry.

When used: When edge condition impacts forming, coating, or downstream assembly.

Bar and Rod Cut-Off Blades (Station-Defined)

What it is: Cut-off blades designed around bar/rod cutting stations.

When used: When cut face quality and tool life must be balanced under high loads.

Tube/Profile Cut-Off Blades (Station-Defined)

What it is: Blades used in tube/profile cutting stations (method-defined).

When used: When clean cuts are needed without deformation beyond acceptable limits.

Specialty Notching/Punch-Assist Knife Elements (Station-Defined)

What it is: Knife elements used with dies or anvils for notching/cutouts.

When used: When station design requires combined cutting and punching functions.

Edge-Reinforced Shear Blades (Micro-Bevel / Honed)

What it is: Edge preparations that improve stability and reduce chipping.

When used: When chipping or rapid edge breakdown dominates despite adequate sharpness.

Wear-Focused Blades for Abrasive Scale/Contamination

What it is: Material and surface strategies biased toward wear resistance.

When used: Lines with scale, grit, or contamination that accelerates dulling.

Toughness-Focused Blades for Impact Duty

What it is: Specifications tuned to resist brittle fracture under shock.

When used: Cropping/heavier stations where impact is the primary risk.

Materials, Heat Treat & Coatings (Brief + Cross-Links)

Metal processing blades are largely defined by heat treat and edge stability, then refined by wear strategy. 

Carbon & tool steels

Common base for shear/slitter knives with tunable properties. → Materials: Carbon & Tool Steels

Coatings & surface treatments

Can support wear and galling control in certain cases (application dependent). → Coatings & Surface Treatments

Heat treatment & hardness

Tuned for the specific balance of wear vs chipping for your metal grade and thickness. → Heat Treatment & Hardness

Stainless steels

Used only for niche cases where corrosion exposure dominates (application-defined). → Materials: Stainless Steels

Carbide

For select extreme wear needs (application dependent). → Materials: Carbide

Quality & Inspection (No Fake Certs)

Metal cutting is sensitive to geometry. Inspection scope can be aligned to your most critical outputs: 

Quality options can include:

If your line requires controlled burr direction or minimal burr, include that requirement during quoting.

Frequently Asked Questions

What causes burrs and rollover in metal shearing?

Burr and rollover are typically driven by clearance, edge wear, and alignment. Blade geometry and heat treat also influence how the edge holds up under load. 

Blade drawings plus metal grade and thickness range, and whether you need upper/lower sets. Burr direction requirements and current failure mode speed up correct specification. 

Lane variation often comes from runout, stack/spacer inconsistency, or differences in knife wear. Set-level matching and inspection aligned to functional datums are key.

Chipping can indicate impact overload, brittle hardness/toughness balance, or contamination. Edge prep and heat treat strategy are common levers to improve stability.

Yes. Sample-based matching is supported for legacy equipment, especially for sets and slitter stacks.

Yes. Many metal operations depend on set-level consistency for cut quality and quick changeovers.

Runout should be specified relative to the functional mounting datum (bore/hub). If you share your arbor/hub details, we can propose practical callouts.

In some cases, coatings and surface treatments can help with wear or galling, but suitability depends on the operation and material. They’re evaluated case-by-case.
