HALANSM® D28 H15 M11 SP-S High-Speed Laser Nozzle
Aftermarket single-layer stepped copper nozzle for fiber laser cutting heads
HALANSM® HLN-SPS-D28H15M11 is an aftermarket laser cutting nozzle sized OD 28mm x H 15mm x thread M11, built for RayTools®, WSX, Precitec®, BOCI and compatible fiber laser heads to deliver stable high-speed cutting performance.
Product Overview
The HALANSM® HLN-SPS-D28H15M11 is a single-layer, stepped-bore laser cutting nozzle that mounts at the front of the cutting head. It shapes and accelerates the assist gas around the focal point, ejecting molten slag while keeping the laser beam coaxial with the gas flow. The stepped internal profile provides secondary acceleration for stronger, more laminar flow.
Key Advantages
High-Speed Stepped Profile
Internal boost steps re-accelerate assist gas for thorough slag removal and faster cutting, especially on carbon steel with oxygen.
High-Conductivity Copper
Precision-machined from T2 red copper for excellent thermal and electrical conductivity, reducing heat buildup and deformation at the tip.
Smooth Inner Wall, High Concentricity
CNC-machined bore and polished inner wall keep the beam and gas precisely coaxial, producing clean kerfs with less dross and oxidation.
Slag-Resistant Finish
Available in natural copper or chrome-plated finish. The hard surface resists wear and slag adhesion for longer, more consistent service.

Selection and Compatibility
The D28 x H15 x M11 form factor is shared across a wide range of fiber laser heads. Confirm exact specs with us before ordering, especially thread pitch and ceramic-ring seat type.
· BOCI BLT series and Han's Laser heads accepting D28 H15 M11 nozzles
· Provide your head model and original part number for fitment check.
D28 H15 family at a glance:
· D28 x H15 x M11, SP-S single layer: calibre 1.0 - 5.0 mm (this product)
· D28 x H15 x M11, double layer (DE / ST-S): confirm bore range with supplier
· D32 x H15 x M14: RayTools / WSX double-layer heads (different thread — do not interchange)
Installation and Handling
Power down the laser and release all assist-gas pressure before starting.
Unscrew the worn nozzle from the cutting head and set it aside.
Clean the mounting seat and ceramic ring with lint-free cloth; inspect for damage.
Thread the new HALANSM® nozzle by hand, align it flush, then tighten finger-tight.
Restore gas, perform a test pierce and a low-power test cut to verify alignment and cut quality.
Storage advice: keep nozzles in their trays, dry and dust-free; avoid touching the bore.
Frequently Asked Questions
What laser heads fit the HALANSM® HLN-SPS-D28H15M11 nozzle?
It fits cutting heads that accept a D28 x H15 x M11 single-layer nozzle, including RayTools BM/BS, WSX, Precitec ProCutter, BOCI BLT and Han's heads. Provide your head model for fitment confirmation.
What material is the HALANSM® SP-S nozzle made from?
It is machined from T2 red copper for high thermal and electrical conductivity, with a natural or chrome-plated finish for wear and slag resistance.
How do I choose the right SP-S bore caliber?
Use smaller bores such as 1.0 - 1.5 mm for thin sheet and fine detail, 2.0 - 2.5 mm for general cutting, and larger sizes for thicker material and higher gas flow. Confirm exact specs with us.
What gas should I use with the SP-S nozzle?
The stepped bore works with oxygen, nitrogen or compressed air assist gas. Follow your machine manufacturer's gas-pressure recommendations.
How do I know the nozzle needs replacing?
Replace it when the bore shows wear or eccentricity, slag repeatedly builds up on the tip, or cut edges lose quality and dross increases.
Can I install the HALANSM® nozzle myself?
Yes. After powering down and relieving gas pressure, hand-thread it onto the cleaned seat, finger-tighten, then run a test cut to confirm alignment.
