The Toolex Reamer with a straight shank and spiral flute is engineered for precise hole enlargement and finish work in metalworking. Designed for machinists who demand consistent bore accuracy, this HSS-E reamer delivers reliable performance across a range of materials.

• Diameter: 3.45 mm
• Shank type: Straight shank — compatible with most toolholding systems including collets and chucks
• Material: HSS-E (high-speed steel with cobalt) for improved hardness and heat resistance
• Flute design: Spiral flute for efficient chip evacuation and smoother cutting action
• Precision: Known for accurate size control and smooth hole finishes with tight tolerances

By combining a rigid straight shank with the heat-tolerant cobalt-infused HSS-E construction, this reamer maintains diameter integrity under demanding cutting conditions. The spiral flute design reduces chip buildup, enabling consistent cuts and longer tool life. Ideal for enlarging existing holes or achieving a precise final bore in steel, aluminum, and other common metals. Its compatibility with standard toolholding systems makes it a flexible choice for CNC and manual machines alike, helping you streamline setups and produce repeatable results with each run.
