Toolex's straight-shank, spiral-flute reamer in HSS-E is built for precision hole enlargement and finishing, ideal for machinists and job shops that demand consistent bore sizes and smooth finishes.

• Diameter: 9.11 mm
• Material: HSS-E (high-speed steel with cobalt) for exceptional wear resistance and heat tolerance
• Flute design: Spiral flute provides efficient chip evacuation and reduces chip buildup for cleaner cuts
• Shank type: Straight shank offers reliable clamping and compatibility with a wide range of tool-holding systems
• Precision: Delivers accurate bore enlargements with tight tolerances and a consistent surface finish
• Applications: Suitable for enlarging existing holes and finishing to the final diameter across a broad spectrum of materials

With its durable HSS-E construction and efficient spiral flute, this reamer minimizes heat buildup and chip accumulation, supporting longer tool life and fewer rework passes. The straight shank design ensures stable, axial alignment when mounted in collets, chucks, or holders, enabling reliable performance across multiple passes. Ideal for both prototype work and production environments, it helps you achieve repeatable bore sizes and smooth finishes that improve part interchangeability and assembly reliability. For best results, maintain proper alignment and provide adequate lubrication to preserve tight tolerances and a clean bore across varied materials.
