The Toolex Reamer with a straight shank and spiral flute is built for precision hole enlarging and finishing. Crafted from HSS-E (high-speed steel with cobalt), it combines durability with excellent heat resistance for demanding metalworking tasks.

• Diameter: 4.38 mm
• Shank: Straight shank design for compatible mounting in multiple tool-holding systems
• Flute geometry: Spiral flute aids efficient chip evacuation and smoother cutting action
• Material: HSS-E (high-speed steel with cobalt) for enhanced hardness and wear resistance
• Applications: Ideal for precise bore enlargement and finishing across a broad range of materials

With its robust construction and precision-ground features, this reamer ensures true, circular holes with tight tolerances and a smooth bore finish. The spiral flute reduces chip buildup, lowers cutting temperature, and extends tool life, while the straight shank provides flexible compatibility with standard tooling setups. Use it to restore or achieve a precise final diameter in pre-drilled holes, delivering consistent results across batches and projects—from fabrication and automotive components to general engineering tasks.
