Expansion Reamers

Designed for precision, our high-speed steel straight shank expansion reamers are perfect for enlarging or finishing existing holes to exact tolerances. Featuring an adjustable screw, these reamers allow for the expansion of the cutting head, enabling regrinding to the original size. This innovative design significantly extends the tool's lifespan by compensating for wear on the cutting edge, ensuring consistent performance.

Designed for precision and durability, our High-Speed Steel Morse Taper Shank Expansion Reamers feature a Morse taper shank for seamless integration with compatible tools or adapters like Morse taper sleeves or sockets. This design ensures optimal efficiency during installation and removal. The self-locking mechanism, powered by the friction between the shank and toolholder, guarantees precise centering. Ideal for enlarging or finishing holes to exact tolerances, these reamers come with an adjustable screw to expand the cutting head, enabling regrinding to its original dimensions. This innovative feature significantly extends the tool's lifespan by compensating for wear on the cutting edge.
