The right model choice depends on thread range, material, center distance and torque need. This guide offers a practical checklist that makes the decision between the AR340 and AR810 easy.
Quick decision table
The general rule is simple: the AR340 for small threads and tight center distances, the AR810 for wide thread ranges and high torque. But the final decision is set by material and part geometry.
| Feature | AR340 | AR560 | AR810 |
|---|---|---|---|
| Thread Range | M3–M4 | M5–M6 | M8–M10 |
| Pilot Drill Ø | 2.80–3.70 mm | 4.65–5.55 mm | 7.40–9.30 mm |
| Power (Motor) | 400 W | 400 W | 750 W |
| Tap Speed | 3000 rpm | 1460 rpm | 2500 rpm |
| Stroke (X) | 13–17 mm | 18–20 mm | 22–25 mm |
By thread range
With its compact body the AR340 is ideal for the M3–M4 range in tight center-distance progressive dies. The AR810 covers the M8–M10 range and is built for wider, more powerful applications.
- M3–M4 · tight space → AR340
- AR560 — medium threads, balanced speed
- M8–M10 · high torque → AR810
- Thin sheet · small thread → AR340
- Thick sheet · cast part → AR810
Torque and material
Forming threads in hard, thick materials needs more torque. The AR810's 750 W servo gives stable performance on demanding materials like stainless steel and thick sheet. The AR340's 400 W is enough for aluminum and thin steel.
Selection checklist
Before deciding, clarify these four points: target thread size, material type and thickness, center distance in the die, and required cycle speed. With this the right model almost picks itself.
