Finixa Pneumatic Orbital Sander Ø150 mm: 2.5 mm or 5.0 mm Orbit?
To achieve reproducible results in paint preparation, intermediate sanding, or finishing, you need more than just the right abrasive—you need the right orbit (stroke). The Finixa SAM series offers two practical variants: 2.5 mm orbit for fine finish work and 5.0 mm orbit for preparation and higher material removal.
Product Overview: Which Variant Fits Which Application?
| Variant | Orbit | Recommended Use | Practical Benefit |
|---|---|---|---|
| Finixa SAM 00 | 2.5 mm | Finishing, fine intermediate sanding, P400 to P3000 as a guideline | Finer scratch pattern, less risk of deep sanding marks |
| Finixa SAM 01 | 5.0 mm | Preparation, putty/filler sanding, P40 to P360 as a guideline | More removal and faster work in preparatory sanding processes |
Sanding pad size for common bodywork and painting tasks.
Designed for central vacuum, self-generated vacuum, and non-vacuum work.
Vibration value as stated in the technical data sheet.

Recommended Basic Settings as Guidelines
The Finixa data sheets provide technical average values. The following settings are therefore intentionally formulated as practical guidelines and should be adjusted based on abrasive, substrate, extraction, and desired result.
| Process Step | Machine | Setting |
|---|---|---|
| Preparation / Removal | SAM 01, 5.0 mm | Higher speed, steady feed rate, active vacuum extraction |
| Intermediate Sanding | SAM 00 or SAM 01 depending on removal | Medium speed, low pressure, overlapping passes |
| Finishing | SAM 00, 2.5 mm | Controlled speed, very low contact pressure, clean abrasive |
Professional Workflow in 6 Steps
- Inspect the Substrate: Define your goal: material removal, preparation, intermediate sanding, or finishing.
- Select the Orbit: 5.0 mm for prep work, 2.5 mm for a finer scratch pattern.
- Connect Extraction: Use the 3-in-1 system appropriate for your workshop environment.
- Set Speed: Start with a moderate setting and increase only as needed.
- Work Flat: Place the machine flat on the surface, overlap paths, and avoid tilting.
- Check Results: Clean the sanded surface, check with guide coat or light before proceeding.
Troubleshooting: Common Problems and Quick Fixes
1. Visible Sanding Pigtails
- Reduce pressure and guide the machine flat.
- Switch to 2.5 mm orbit for finishing work.
- Replace abrasive if it is clogged or damaged.
2. Insufficient Material Removal
- Use 5.0 mm orbit for preparatory tasks.
- Increase speed using the integrated regulator.
- Check grit size and condition of the abrasive.
3. Rough/Unsteady Operation
- Check compressed air supply and air consumption.
- Inspect the sanding pad and its mounting.
- Do not tilt the machine sideways.
4. Dust Build-up on Surface
- Select correct extraction mode: central, self-generated, or none.
- Align the hole pattern of the pad and abrasive correctly.
- Clean the surface regularly, especially before finishing steps.
Maintenance: 5 Points for Consistent Performance
- Regularly check the sanding pad for wear and flatness.
- Keep extraction channels clean for effective dust removal.
- Monitor compressed air quality and supply.
- Keep regulators, switches, and air inlets free from dirt.
- In case of power loss or unusual noise, have the motor/bearing unit professionally inspected.
FAQ
Which variant is better for finishing work?
For finishing and fine sanding patterns, the SAM 00 with a 2.5 mm orbit is the ideal choice.
When should I use the 5.0 mm orbit?
The SAM 01 with 5.0 mm orbit is suitable for preparation, higher material removal, and coarser sanding tasks.
Can I work with dust extraction?
Yes, both variants are described as 3-in-1 systems for central extraction, self-generated vacuum, and working without extraction.
Are the technical values fixed maximums?
No. The data sheets indicate that the values provided are averages, and suitability should always be verified for the specific application.
Which machine should a paint shop buy first?
For frequent preparation work, the 5.0 mm variant is very versatile. Those who do extensive finishing and fine sanding should ideally supplement it with the 2.5 mm variant.
