Single Nozzle D28 / M11 / H15 – B type (1.2E mm – 4.5E mm)

Description

High-quality copper single-layer laser nozzle (B-type design) engineered for stable gas flow and precise cutting performance in fiber laser systems. The B-type structure provides reliable airflow characteristics and improved durability, making it suitable for consistent industrial cutting operations.

Specifications:

• Type: Single Layer (SP-type, B-type design)
• Aperture (Diameter): 1.2E mm – 4.5E mm (selectable options)
• Outer Diameter: 28 mm (D28)
• Thread: M11 × 0.75
• Height: 15 mm (H15)
• Material: High-quality copper

Available Sizes:

1.2E · 1.4E · 1.6E · 1.8E · 2.0E · 2.5E · 3.0E · 3.5E · 4.0E · 4.5E mm

Key Features:

• Single-layer structure ensures smooth and stable gas flow
• B-type geometry enhances durability and operational stability
• High concentricity for accurate laser beam alignment
• Reduced turbulence for cleaner cuts and less slag
• Copper construction provides excellent heat resistance and long service life

Compatibility:

Compatible with fiber laser cutting heads using D28 / M11 / H15 standard, including:

• BOCI (Bochu) – BLT series (421, 441, 461, 481, etc.)
• Raytools – BM110, BM111, BM06K, BM114, BM115
• Precitec – ProCutter, LightCutter, SolidCutter
• WSX cutting heads
• Han’s Laser systems
• Compatible with other fiber laser machines using M11 / D28 standard

Applications:

• Designed for nitrogen (N₂) or air-assisted cutting
• Ideal for:
  • Stainless steel
  • Aluminum
  • Brass and non-ferrous metals
• Suitable for medium to heavy thickness cutting depending on diameter

 Single-layer nozzles are typically used for stainless steel and non-ferrous cutting, while double-layer nozzles are used for mild steel (oxygen cutting).

Recommended Usage by Diameter:

• 1.2 – 1.4 mm → Thin sheets (1–3 mm)
• 1.6 – 1.8 mm → Medium thickness (3–6 mm)
• 2.0 – 2.5 mm → Thick materials (6–10 mm)
• 3.0 – 3.5 mm → Heavy cutting (10–16 mm)
• 4.0 – 4.5 mm → Extra heavy-duty cutting (16 mm+)

💡 Note:

B-type single nozzles belong to the same single-layer (SP-type) family but feature a slightly different geometry. They are widely used across multiple laser cutting systems due to their universal D28 / M11 / H15 compatibility and consistent performance.
