Single Double Layer Fiber Laser Cutting Nozzle D11 H19 M8 BOCI BLT421T BLT441T
The D11 × M8 × H19 single- and double-layer 3D laser cutting nozzle is a precision component designed for multi-angle and spatial fiber laser cutting applications. With a compact diameter and optimized height, this nozzle is engineered to deliver stable assist-gas control and accurate laser alignment in 3D cutting environments. It is fully compatible with BOCI BLT421T and BLT441T cutting heads and can be used as a reliable replacement solution for corresponding original 3D nozzle configurations.
Key Features
This nozzle is available in both single-layer and double-layer structures, allowing users to select the appropriate configuration based on cutting requirements. The single-layer version provides direct and efficient gas delivery for fine and thin-material cutting, while the double-layer design enables enhanced gas shielding and improved stability during angled or complex cutting paths. Precision-machined orifice geometry ensures excellent concentricity, supporting consistent kerf width and clean cut edges. Manufactured from high-quality copper alloy, the nozzle offers strong thermal conductivity, resistance to deformation, and stable performance under continuous laser operation. The M8 thread design ensures secure installation and accurate positioning in compact 3D cutting heads.
Applications
This nozzle is ideal for 3D laser cutting of carbon steel, stainless steel, aluminum, and other metal materials requiring angled cuts, contour processing, or spatial cutting. Typical applications include formed sheet metal parts, structural components, tube processing, and precision metal assemblies where cutting accuracy and surface quality are critical.
