Standard Boring Range: 2.875" to 5.250" (approx. 73 mm to 133.3 mm).
Design: Built as a heavy-duty shop machine rather than a portable boring bar, it mounts engine blocks to maintain true perpendicularity and alignment between the new cylinder bores and the original crankshaft/main bearing centerlines.
Application: Primarily engineered for re-boring and sleeving American, European, and Asian passenger car and truck engine blocks (including inline and 60°/90° V-type configurations).
Control: Legacy models typically feature manual or basic digital feed/controls, predating the modern fully-programmable "Point and Shoot" CNC setups found on current Rottler centers like the F69A or F10XS.
Extended Capability: With optional smaller or larger heavy-duty cutterheads and specialized tool holders, the overall machine limits can reach down to 1.500" and up to 9.000".
