Conical hand reamers in HSS are tools designed for machining conical holes, ensuring precision in finishing and dimensional calibration. Made of high-speed steel, they offer good wear resistance during manual reaming operations. The conical shape allows gradual insertion and accurate control of the machining depth, particularly useful in applications requiring tight tolerances. These reamers are suitable for use on metallic materials, enabling the achievement of smooth and regular internal surfaces. Their design is engineered to ensure stability and ease of handling during manual use.
