Lathe Parting Off Tool

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

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.
