The Comec AC200 is a versatile, heavy-duty cylinder boring machine designed for reconditioning engine blocks from cars, trucks, and light commercial vehicles. It handles a broad bore range and comes equipped with precision controls, making it well-suited to shops that rebuild blocks in-house. The AC200 combines a robust mechanical structure with updated technical solutions, delivering reliable performance and finishing quality for manual or performance-oriented engine work.
As a shop-ready tool, the AC200’s adjustable speeds, variable feed, and precise centering system give flexibility for different cylinder sizes and materials — from small-bore automotive blocks to larger truck applications within its supported range.

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.
