Application:  Ident. No. 361–372: Pitch errors are compensated for with minimal length
For thread cutting on machine tools with synchronous spindles. With rigidly compensation of 1.0 mm under tension and 0.2 mm under pressure
clamped screw taps, pitch errors cause high axial forces that can be compen-  Ident. No. 371–372: straight shank similar to DIN 1835 B+E
sated for by synchronous tapping chucks through minimal length compensation
under pressure and tension. Advantage:
 Secure clamping in quick-change inserts for ER collet chucks
Execution:  Ident. No. 341–362: Increased tool service life
 Clamping screws to secure against rotation of the clamped screw tap  Ident. No. 371–372: increased tool service life
 thread-cutting quick-change chuck for synchronous spindles
