HALANSM® SP-S High-Speed Laser Nozzle D28/H15/M11
Aftermarket SP-S high-speed single layer nozzle, OD28 x H15 x M11, natural copper or chrome plated, built for RayTools, WSX, Precitec, BOCI and Ospri-compatible fiber laser cutting heads.
HALANSM® HLN-SPS-D28H15M11 is an aftermarket SP-S high-speed laser nozzle sized OD28 x H15 x thread M11, built for RayTools, WSX, Precitec, BOCI and Ospri-compatible fiber laser cutting heads to deliver stable gas flow, fast cutting speed and a smooth, slag-free surface finish.
Product Overview
The HALANSM® SP-S high-speed nozzle is a single layer, conical high-speed cutting nozzle in the D28-H15-M11 standard. It sits at the base of the laser cutting head and focuses the assist gas through an internal boost step, driving molten material away from the kerf at high velocity.
Made from high-purity T2 copper with optional chrome plating, it offers excellent thermal and electrical conductivity, oxidation resistance and a stable capacitance signal. The stepped internal bore is the defining feature of the SP-S family: it creates a de Laval-like secondary acceleration of the gas stream, which is why the SP-S is specified for high-power, high-speed bright-surface cutting.
Key Advantages
Stepped internal bore for high-speed cutting
· The conical bore includes an internal boost step that accelerates assist gas to supersonic velocity.
· Result: stronger slag ejection, cleaner kerf walls and higher cutting speed on thick plate.
Natural copper or chrome plated
· Standard finish is high-purity T2 copper for maximum heat dissipation and conductivity.
· Chrome plating is available for improved surface hardness, oxidation resistance and anti-slag performance.
Hexagonal knurling for secure handling
· Six-face knurled body gives positive grip during hand tightening in the cutting head.
· Consistent shoulder geometry seats repeatably against the ceramic ring, aiding concentricity.
Batch consistency and inspection
· Each production batch is checked for bore concentricity and dimensional accuracy.
· Packaged 10 pieces per box to keep spares clean, organised and ready for replacement.

Selection Guide: D28 Nozzle Family
Within the D28 28 mm outer-diameter family, the deciding dimensions are height, thread and internal structure. Use this table to avoid mixing M11 and M14 interfaces or confusing SP-S with double-layer types.

Installation and Handling
1. Power down the laser and lock out the cutting head. Release any residual gas pressure.
2. Unscrew the worn nozzle. Do not lever against the ceramic ring or sensor contacts.
3. Clean the nozzle seat, threads and ceramic ring from slag, dust and debris.
4. Align the new HALANSM® nozzle by hand and thread it onto the M11 nozzle seat.
5. Hand-tighten to a firm stop. Do not overtighten; use a snug fit, not a wrench torque.
6. Recalibrate capacitance / focus as required by the cutting head manufacturer.
7. Run a test cut on scrap material to verify gas flow, concentricity and cut quality.
Storage: keep unused nozzles in their original box, dry and oil-free. Handle by the knurled body to avoid contaminating the bore with skin oils.
FAQ — Frequently Asked Questions
Q: What laser cutting heads fit the HALANSM® HLN-SPS-D28H15M11 nozzle?
It fits RayTools BT240/BM110, WSX, Precitec, BOCI and Ospri-compatible heads using the D28 x H15 x M11 interface. Provide your head model and original part number for fitment check.
Q: What is the difference between SP-S and a regular single-layer nozzle?
SP-S has a stepped internal bore that accelerates assist gas to supersonic velocity for stronger slag ejection and higher cutting speed. The regular S nozzle uses a plain conical bore.
Q: Should I choose natural copper or chrome plated?
Natural copper gives the best thermal and electrical conductivity. Chrome plating adds surface hardness and oxidation resistance for heavy-duty or high-power operations.
Q: Which aperture size should I use?
Use 1.0-1.6 mm for thin stainless and aluminum, 1.8-2.5 mm for medium thickness, and 3.0-5.0 mm for thicker plate. Confirm exact specs with us for your material and laser power.
Q: Can this nozzle be used for oxygen cutting carbon steel?
Yes. The SP-S single layer supports nitrogen, air and oxygen assist. For dedicated heavy carbon-steel cutting, a double-layer D/E nozzle is also an option within the same D28 family.
Q: Do I need to recalibrate after replacing the nozzle?
Yes. After installation, recalibrate capacitance and focus according to the cutting head manual, then run a test cut to confirm concentricity and cut quality.
