Carbide Reamers

Engineered for tight tolerance hole finishing, Retop carbide reamers deliver unmatched surface finish, dimensional accuracy, and extended tool life in high-speed machining.

Product Description

Carbide reamers are precision cutting tools used to enlarge or finish existing holes to an exact diameter with high concentricity and smooth surface finish. Made from ultra-hard tungsten carbide, these reamers offer excellent wear resistance and rigidity, even when machining hardened steel or abrasive materials. Retop manufactures both solid and brazed carbide reamers with various flute geometries to meet complex manufacturing requirements.

Carbide reamers are essential in industries such as automotive, aerospace, mold making, medical devices, and high-precision manufacturing. They are commonly used for finishing holes in engine blocks, transmission components, hydraulic parts, valve bodies, injection molds, and medical instruments. Their ability to maintain tight tolerances makes them ideal for critical fit applications.
