Toolex Reamers deliver precise hole enlargement and finishing at a 0.78 mm diameter, built with a straight shank and spiral flute for efficient cutting and chip control. Made from HSS-E (high-speed steel with cobalt), these reamers are designed for durability and heat resistance in demanding machining environments. They are suitable for a wide range of materials and applications, offering consistent, smooth holes and tight tolerances. Spiral flute improves cutting efficiency: The spiral design enhances chip evacuation, reducing buildup and supporting smoother, more consistent hole completion. Straight shank for broad compatibility: The straight shank works with a wide range of tool holding systems, enabling quick setup across multiple machines and setups. HSS-E for durability and heat resistance: Cobalt-enriched high-speed steel delivers longer tool life and stable performance under heat, helping maintain precision over many operations. These reamers help you achieve precise hole sizes with a smooth finish, improving part quality while reducing rework and downtime. The durable HSS-E material and reliable design deliver consistent performance across materials, making setup and production faster and more predictable.
