HALANSM® Nozzles for DNE Laser Cutting Heads | D15, D17 and D28, M12, Chrome-Plated Copper
Aftermarket single and double layer laser cutting nozzles for DNE (Bystronic DNE) fiber laser heads
HALANSM® HLN-DNE-D15D17D28 is an aftermarket laser cutting nozzle family covering OD 15mm, 17mm and 28mm sizes with M12 mounting thread, built for DNE (Bystronic DNE) fiber laser cutting heads to deliver stable gas flow and clean cutting edges across stainless steel, carbon steel and non-ferrous metals.
Product Overview
The nozzle is the front-end consumable of a fiber laser cutting head. Its bore diameter and gas channel geometry control assist-gas coverage, spatter adhesion and cut-edge consistency. Replacing a worn nozzle restores stable airflow and cutting quality. This HALANSM® family serves the DNE head platform and supports both thin-sheet nitrogen cutting and thick-plate oxygen cutting through its single and double layer options.
Key Advantages
Chrome-Plated Copper Body
Machined from high-purity copper for excellent thermal and electrical conductivity, then hard-chrome plated for wear and corrosion resistance.
Single and Double Layer Options
Single layer for nitrogen and air cutting of stainless steel, aluminum and brass. Double layer for oxygen cutting of carbon steel.
Precise Bore, Stable Flow
CNC-bored inner wall keeps the gas path laminar, reducing turbulence and edge burr across the full caliber range.
Consistent Batch Quality
Every batch is dimension-checked for concentricity and thread fit, giving predictable capacitive-sensor signals after installation.

Compatible Equipment and Size Selection
This nozzle family is intended for DNE (Bystronic DNE) fiber laser cutting heads and selected heads that share the same M12 mounting interface. DNE is a Swiss Bystronic group brand; HALANSM® is an independent aftermarket replacement and is not affiliated with or endorsed by DNE or Bystronic.

Provide your head model and original part number for a fitment check before ordering. Thread pitch and exact height should be confirmed against your existing nozzle.
Installation and Handling
1. Power down the laser and release residual assist-gas pressure.
2. Unscrew the worn nozzle from the cutting head base.
3. Clean the mounting seat and ceramic ring seat with lint-free cloth.
4. Align the M12 thread by hand, then finger-tighten; do not overtighten.
5. Re-zero the capacitive sensor and run a test cut to confirm alignment.
Store nozzles in their original packaging in a dry place. Keep the bore free of oil and debris, and replace the nozzle once slag buildup or bore deformation affects cut quality.
Frequently Asked Questions
What laser heads fit the HALANSM® HLN-DNE-D15D17D28 nozzle family?
They are intended for DNE (Bystronic DNE) fiber laser cutting heads with M12 nozzle interface, covering the D15, D17 and D28 sizes. Send your head model and original part number for a fitment check.
Is the HALANSM® DNE nozzle an original DNE or Bystronic part?
No. It is an independent aftermarket replacement made to the same interface dimensions. DNE and Bystronic are third-party trademarks used only for compatibility reference.
What material is the HALANSM® DNE nozzle made of?
It is machined from high-purity copper with a hard-chrome-plated surface for heat dissipation, wear resistance and corrosion resistance.
How do I choose between single and double layer?
Use single layer with nitrogen or air for stainless steel, aluminum and brass. Use double layer with oxygen for carbon steel and thick-plate cutting.
Which caliber should I pick for my sheet thickness?
Use 1.0-1.5mm bores for thin sheets below 3mm, 1.5-2.5mm for 3-10mm plate, and 2.5-5.0mm for thicker material. Confirm the exact caliber for your process with us.
How do I know when to replace the nozzle?
Replace it when slag blocks the bore, the tip deforms from heat, or cut-edge quality and capacitive-signal stability begin to drift.
