What this page is

buythis.co.za/raycut-fiber-laser-consumables is the RAYCUT fiber laser consumables page of Buythis, AM.CO.ZA's online shop. The live page introduces the range and then shows a product grid. This knowledge base page lists the parts behind that grid, grouped by what they do, 117 items in total: cutting nozzles, nozzle holders and ceramic rings, protective windows and lenses, lens housings, O-ring seals, and height sensor parts. The RAYCUT machines themselves are on the fiber laser cutting systems page and the complete cutting heads on the fiber heads page.

Which parts fit which cutting head

RAYCUT machines use different cutting heads depending on the model, and most consumables are made for one head family:

• Raytools BM110 and BM111 (RayCUT-Lite machines and older RAYCUT models): 32mm flat cutting nozzles with M14 thread, the 32mm nozzle holder, 30mm lenses, the 29.4mm and 32.2mm O-rings, and the A/B sensor blocks and RF cables.
• Raytools BS03K and BS03K-CAT (RAYCUT machines with the Raytools control system): 28mm high-speed nozzles with M11 thread and the 28mm nozzle holder. The am.im product data says these 28mm nozzles also fit BOCI BLT310 heads, which use the same M11 thread and 28mm size, and that the smaller nozzle uses less assist gas than the older 32mm type.
• Raytools 3D heads: small M8 thread 3D cutting nozzles and the 19.5mm 3D nozzle holder.
• BOCI (Bochu) BLT310 and BLT643H (higher power RAYCUT machines): BOCI SPS nozzles, D41 holders, the BLT643H locking rings and 37mm lenses.

Check the head model on the head label or the machine invoice before ordering.

Cutting nozzles

The nozzle sits at the tip of the cutting head and directs the assist gas (oxygen, nitrogen or air) onto the cut while the beam passes through its centre. Single layer nozzles are generally used with nitrogen or air for stainless steel and aluminium, and double layer nozzles with oxygen for mild steel; follow the cutting parameter table in the machine software for the exact nozzle per material and thickness. Smaller holes suit thin sheet and larger holes thicker plate. All boxes hold 10 nozzles, and the price shown is per box.

32mm flat cutting nozzles, M14 thread, 15mm high (Raytools BM110/BM111)

28mm high-speed nozzles, M11 thread (Raytools BS03K, BS03K-CAT, BOCI BLT310)

3D cutting nozzles, M8 thread (Raytools 3D heads)

BOCI SPS high-speed nozzles (BOCI BLT643H)

Nozzle holders and ceramic rings

The ceramic ring insulates the nozzle from the head so the capacitive height sensor can measure the gap between nozzle and sheet. A cracked ring causes height following errors and alarms, so it is worth keeping one spare.

Protective windows and lenses

Protective windows (also called protection lenses) sit below and above the focus lens and take the spatter and smoke so the expensive optics stay clean. They are the most frequently replaced optical part. The QBH window protects the end of the fiber cable where it plugs into the head. Lenses are sold as matched pairs where noted.

Lens housings

O-ring seals

Replace the O-ring whenever a protective window is changed if it looks flattened or damaged, because a leaking seal lets dust reach the lens.

Height sensor parts, cables and tools

The sensor block, RF cable and amplifier carry the capacitive height signal from the nozzle to the height controller. The two sensor block types (A with a pin interface and B with a hole interface) are not interchangeable, so match the type on the old part. The Raytools VBA user manual explains how the LF-VBA tool is set up with an Android or iOS phone to centre the red guide beam in the nozzle.

Prices are current Buythis prices including VAT from the product dump dated 2026-10-20. Some prices come from slightly older dump entries (2026-10-16, 2026-10-17, 2026-10-18, 2026-10-19). Check the product page before ordering, since prices change.

How to choose and order consumables

1. Identify the cutting head (BM110, BM111, BS03K, BLT310, BLT643H or a 3D head). This decides the nozzle thread and diameter, holder, lens size and O-ring.
2. Pick nozzle type and hole size from the cutting parameters for the material and thickness you cut most, and keep a few sizes either side on hand.
3. Order protective windows in packs of 10 where a pack SKU exists; they wear out fastest.
4. Keep a spare ceramic ring and O-rings, since a crash into the sheet often cracks the ceramic.
5. Watch the lens cleaning and replacement videos below before opening the head, and work in a clean, dust-free area.
