Raytools Laser Cutting Heads for Fiber Lasers
A laser cutting head is the optical assembly that collimates the fiber beam, focuses it onto the workpiece, and delivers the assist gas that blows molten metal out of the cut. Edge quality, piercing, spot size and cutting speed are all decided inside this one unit, which is why the head matters as much as the laser source feeding it.
We stock genuine Raytools laser cutting heads for fiber lasers from 1.5 kW up to 40 kW, covering flatbed sheet cutting, dedicated tube cutting, 5-axis 3D work and robot-mounted heads for automated cells. The idea is to match the head to how your machine actually moves, rather than forcing a generic part to fit.
Raytools AG (Switzerland) is one of the reference brands in fiber cutting optics, alongside Precitec and WSX, and its heads run on a large share of the cutting machines used across India. That keeps lenses, ceramic rings and nozzles easy to restock locally. Which family you need comes down mostly to power and motion: the BM and BT series handle sheet and tube, the BD and GF series cover robotic and multi-axis cutting, the FM series is built for fine and micro work, and the high-power BS series is made for thick-plate production at 8 kW and beyond.
What Is Inside a Raytools Cutting Head
- Auto-focus under program control. The focusing lens moves through roughly 8 to 14 mm of focus travel (depending on series) at about 0.05 mm repeatability, so you can pierce thick plate and switch thickness without touching the head.
- Protected optics. The collimating and focusing lenses sit behind a drawer-type protective window that takes the spatter, swaps out in seconds, and saves the costlier lens above it.
- Water-cooled lens groups. D28, D30 and D37 lens sets (model dependent) rated for continuous high-power duty without focus drift.
- QBH / QD fiber connectors. Compatible with IPG, Raycus, Max and other common fiber sources.
- Capacitive height sensing. Holds a steady standoff over warped or pre-rusted sheet, so edges stay consistent across the bed.
Raytools Cutting Head Range: Which Head for Which Job
Most selection mistakes come from buying on price instead of on motion and power. This is the quick map we use when helping a customer choose:
| Head Type | Typical Raytools Models | Best For | Power Range |
|---|---|---|---|
| Flatbed / sheet (2D) | BM109, BM111, BT240S, BM114S | 2D sheet cutting on gantry machines | 1.5 to 6 kW |
| Tube & profile | BD04K, BT240S TubeCut | Round and square tube, T-profiles | up to 8 kW |
| 3D / 5-axis | BD04K-3D, BM114S-PC 3D | Bevels, shaped and 3D parts | 4 to 6 kW |
| Robotic | BT-series RC (e.g. BT240S-RC) | Robot-arm cutting cells and automation | 1.5 to 8 kW |
| High-power smart | BS06K, BS12K, BS20K, BS30K | Thick-plate, high-throughput production | 6 to 40 kW |
Applications & Industries
- Sheet metal fabrication and job-work units
- Tube, pipe and profile cutting lines
- Automotive and auto-component manufacturing
- White goods and electrical panel production
- Robotic and automated cutting cells
- Precision and thin-gauge parts (FM micro heads)
- Heavy plate and structural fabrication
How to Choose the Right Laser Cutting Head
- Match the power. The lens group sets a ceiling, so a 1.5 kW head will not survive a 6 kW source. Pick a head rated at or above your laser output (BM109 to 1.5 kW, BM111 to about 3.3 kW, BM114S or BD04K to 6 kW, BS-series for 8 kW and up).
- Match the motion. A flatbed gantry needs a standard sheet head; tube and profile work needs a tube head with rotary support; bevels and shaped parts need a 5-axis 3D head; a robot arm needs a robotic head with a built-in or external Z-axis.
- Match the material and gas. Mild steel runs on oxygen and tolerates simpler optics; stainless and aluminium need clean nitrogen at higher pressure and cut better with a larger clear-aperture lens.
- Check the connector and spares. Confirm the fiber connector (QBH / QD) matches your source, and that the nozzle, ceramic ring and protective window for that head are easy to restock.

Frequently Asked Questions
A laser cutting head is the core optical assembly on a fiber laser machine that focuses the beam onto the material and delivers the assist gas to the cut. It houses the collimating and focusing lenses, the protective window, the nozzle and ceramic ring, and a capacitive height sensor, and on auto-focus models a motor that shifts the focus to suit different thicknesses.
Match it to your laser power, machine motion and material. As a rough guide, the BM109 suits sources up to 1.5 kW, the BM111 up to about 3.3 kW, and the BM114S or BD04K up to 6 kW, while the BS-series handles 8 kW and above. Flatbed machines use a sheet head, tube machines use a tube-cutting head, and robot cells use a robot-cutting head with a built-in or external Z-axis.
An auto-focus head moves the focusing lens under program control, so it can pierce thick plate and switch between thicknesses without anyone touching the head. A manual-focus head is set by hand and works well for steady, single-thickness cutting at lower cost. Most current Raytools cutting heads are auto-focus.
Yes. Raytools heads ship with standard fiber interfaces, including QBH, QD, Q+ and LOE, which fit IPG, Raycus, Max and other mainstream sources. Before ordering, confirm the connector type on your fiber so we can supply the matching head, and we will check it with you over WhatsApp if you are unsure.
For round, square and T-profile tube, the BD04K is the dedicated tube head, available in 4 kW and 8 kW. For bevels, shaped parts and full 3D work, the BD04K-3D and BM114S-PC 3D are built for multi-axis motion, and robot-mounted RC heads cover automated cells. The right choice depends on your machine's axes and your laser power.
All three are reference brands in fiber cutting optics. Raytools is the most widely deployed in India, which makes its lenses, ceramics and nozzles the easiest to restock; Precitec is positioned at the premium, high-end of the market; and WSX is a common value-to-mid choice. For most fabricators running standard machines, Raytools gives the best balance of performance, availability and spares support.
The protective window, or cover glass. It sits below the focusing lens and absorbs the spatter and fume, so it is a routine consumable. Keeping spares on hand prevents downtime and protects the more expensive focusing lens above it.
Price depends on the series and power. An entry 1.5 kW head starts at roughly ₹1.4 lakh, while tube, 3D, robotic and high-power heads run higher, into several lakh for the largest BS-series units. Contact us for current pricing on the exact model and configuration you need.
