Esko Kongsberg Bld-Sr6375 Carbide Round Shank Knife Blades G4244722
The Esko Kongsberg BLD-SR6375 (Part Number: G42447227 or 42447227) is a premium, single-edge tungsten carbide round shank oscillating knife blade.
This specific blade features a 6mm cylindrical shank with a flatted Weldon-style mounting section, distinguishing it from flat stock blades. It is the industry-standard choice for cutting dense, high-rebound elastomeric materials on digital flatbed tables.

| Max. Cutting Depth | 20.00 mm to 23.00 mm (~0.90 inches) |
| Material | Micrograin Tungsten Carbide (WC) |
Compatible Tool Modules
The round shank design requires high-energy, vertical striking force. The BLD-SR6375 is explicitly engineered to pair with the following Esko Kongsberg tool assemblies:
- Long Stroke Knife Tool (XT / XN / XL platforms)
- MP HF (Multi-Purpose High Frequency) Knife Tool
- Vibracut Tool (with appropriate 6mm round-stock adapter)
Primary Target Application: Die-Ejection Rubber
While standard flat blades flex and tear when hitting high-resistance materials, the thick 6mm rigid steel-like body of this carbide blade avoids deflection. Its primary global use case is cutting die-ejection rubber (e.g., solid rubber profiles, cellular rubber, and push-rubber pads used in industrial steel-rule packaging dies).
Other Suitable Substrates
Beyond die rubber, its heavy-duty design handles dense or porous materials smoothly:
- Industrial Gaskets: Non-asbestos gasket sheets, neoprene, and thick nitrile rubber.
- Dense Signs & Displays: Thick expanded polystyrene (EPS) foam boards, foamed PVC, and structural honeycomb cores.
- Heavy Flooring: Thick industrial felt, carpets, and dense soundproofing mats.
