The Rottler F2MB is a proven, heavy-duty cylinder boring machine designed for precision boring, sleeving, and block repair work. Known for its rigidity, accuracy, and smooth spindle operation, the F2MB is widely used in automotive, diesel, and industrial engine rebuild shops.
As a used machine, the F2MB offers excellent value — giving shops the ability to perform accurate bores, overbores, sleeve installations, and repair machining without the cost associated with newer CNC equipment. The simple mechanical controls, robust column design, and reliable spindle system make this a practical, durable choice for expanding a shop’s block-machining capability.
Rigid, Heavy-Duty Boring Column: Ensures stable, repeatable bores on automotive, diesel, and industrial blocks.
Precision Spindle System: Designed for accurate boring and sleeving with minimal vibration and excellent surface finish.
Large Block Capacity: Can handle a wide range of block sizes — inline engines, V-blocks, light- to mid-duty diesel engines, and industrial applications (within machine limits).
Smooth Manual Controls: Mechanical feed and spindle adjustment provide good operator control without requiring CNC training.
Cost-Effective Used Option: Great for shops that want to add or expand their cylinder boring capability without major capital investment.

Decades before today’s engine shops trusted our equipment, Tony was already deep in the craft — rebuilding motors, machining blocks, and pushing for better precision.
A local newspaper once featured him as a standout young machinist, noting his drive, attention to detail, and obsession with doing things the right way. That same passion would eventually shape our company’s values.
Today, that commitment lives on in every machine we sell, every customer we support, and every shop we help succeed.
