QuadCutOff® – the precision parting off tool lathe solution
QuadCutOff® from Scandinavian Tool Systems is engineered for manufacturers who demand reliable, burr-free cut-offs in CNC and manual lathes. This high-speed-steel (HSS) system with TiN coating excels where carbide struggles: thin-wall tubing, softer alloys and low cutting-speed applications. Thanks to razor-sharp, ground cutting edges, it delivers clean separations, minimal chatter and extended tool life even on light-duty machines.
Two insert families for optimum diameter coverage
| Insert series | Max solid bar Ø | Typical tube Ø* |
| Q16 | 13 mm | up to ~24 mm |
| Q25 | 20 mm | up to ~32 mm |
*Larger tube diameters are possible because the blade stops short of centre; refer to the application diagram for exact limits.
Recommended cutting speed (m/min)
- Low-carbon steel < 650 N/mm²: 40–60
- Carbon steel 650–850 N/mm²: 30–40
- Alloyed & heat-resistant steels: 30–40
- Stainless steel: 30–40
- Cast iron HB 150–250: 20–30
- Non-ferrous materials: up to 200
Suggested feed per revolution (mm/rev)
| Material | Q16-1.0 | Q16-1.2 | Q16-1.5 | Q25-1.5 | Q25-2.0 |
| Low-carbon steel | 0.08–0.10 | 0.08–0.10 | 0.10–0.15 | 0.10–0.15 | 0.10–0.20 |
| Carbon & alloy steels | 0.04–0.06 | 0.05–0.06 | 0.05–0.10 | 0.05–0.10 | 0.08–0.15 |
| Stainless steel | 0.05–0.06 | 0.05–0.06 | 0.05–0.10 | 0.05–0.10 | 0.08–0.15 |
| Cast iron HB 180–250 | 0.05–0.06 | 0.05–0.06 | 0.05–0.10 | 0.05–0.10 | 0.08–0.15 |
| Non-ferrous | –0.20 | –0.20 | –0.25 | –0.25 | –0.25 |
Why choose QuadCutOff® as your parting off tool for your lathe?
- High precision: repeatable insert indexing maintains tight tolerances on part length.
- Lower spindle power: HSS geometry produces thinner chips, reducing cutting forces.
- Extended versatility: one holder accepts both Q16 and Q25 inserts for rapid change-overs.
- Reduced downtime: robust clamping and star-drive screw enable quick, secure insert swaps.
