Toolex Reamer with a straight shank and spiral flute is designed for precision hole enlarging and finishing, ideal for professionals who demand accurate bore sizes and consistent surface quality. Diameter: 12.47 mm for precise hole sizing and finishing passes Material: HSS-E (high-speed steel with cobalt) for enhanced hardness, heat resistance, and longer tool life Flute Design: Spiral flute geometry to promote efficient chip evacuation and smoother cutting action Shank Type: Straight shank ensures straightforward clamping in a wide range of tool-holding systems Applications: Suitable for enlarging existing holes or achieving tight tolerances across a variety of materials This reamer delivers reliable, repeatable performance with a geometry that minimizes chip buildup and heat generation. The straight shank and spiral flute combination supports quick setups and efficient machining workflows, while the cobalt-infused HSS maintains a sharp cutting edge under demanding reaming operations. Use it for precise bore finishing where dimensional accuracy and a smooth bore surface are essential, across metalworking, fabrication, and engineering applications.
