The FA machines are the industry standard worldwide for boring bars. Designed for all automotive blocks up to big block V8's and small diesel blocks, the F9A will produce accurate bores for a lifetime. The F9A is ideal for the production shop where the odd sleeve must be fitted. The F9A boring bar is the fastest, most powerful boring machine available to the jobber shop. The simple setup and manual push button controls make this a very user-friendly and economical machine to operate.
Speed - All FA boring bars have the same high performance AC servo motor. Independent feed control allows you to change the feed rate from .001" (.025mm) to .012" (.3mm) per revolution.
Accuracy - The FA series boring bar uses a precision ground ball screw to control feed rate and cutter position. This allows the machines to repeat cutter position accuracy to .0002" (.005mm).
Strength - The Rottler proven spindle and bearing design gives you a rigid machine capable of making heavy sleeve cuts for a lifetime. The F9A spindle has been reduced to allow the machining of compact engines such as motorcycles, marine blocks and others.
Flexibility - With variable feed rates you are able to maximize the performance of the machine. Increase spindle feed rates for simple oversize bores. Decrease feed rates for sleeve cuts or counter bores. The F9A machines can bore from 1.5" (38mm) to 5" (127mm). Special carbide tools are available for counterboring, chamfer cutting, offset boring, and O-ringing.
Reliability - The F Series machines use a high-speed, cogged belt drive system. This and the use of two independent motors to run the spindle speed and feed, entirely eliminates the gear box.
Cost Savings - The high speed Rottler FA boring bar series machine can bore a block in half the time that other boring machines require. New insert technology is producing long lasting, inexpensive inserts which are capable of handling these high speed and feed rates, with the same cost per insert as previous styles. Inserts do not require sharpening and the low cost of these tools makes them the ultimate choice for boring cylinders.

The electronic handwheel provides Manual Operation with two modes. In coarse mode, each "click" of the handwheel will move the machine exactly .001" (.01mm) and in fine mode, each click will move the machine exactly .0001" (.002mm). The pulse hand wheel allows you to feed .0001 per click or .001 per click. The LED reads the actual vertical position in .0001.
