The Toolex Reamer with straight shank and spiral flute is engineered for precise hole enlargement and finishing in metalworking. It’s designed for machinists and workshops that demand repeatable bore quality and smooth, burr-free finishes.

• Diameter: 12.07 mm
• Material: HSS-E (high-speed steel with cobalt) for enhanced hardness and heat resistance
• Shank type: Straight shank for broad compatibility with common tool holding systems
• Flute design: Spiral flute promotes efficient chip evacuation and steady cutting action
• Precision: Delivers accurate holes with tight, consistent tolerances
• Applications: Ideal for enlarging and finishing holes across a range of metals and alloys

This reamer excels at producing clean, dimensionally consistent bores when enlarging pre-drilled holes or finishing new holes to precise specifications. The cobalt-enhanced HSS-E construction stands up to heat and wear, helping maintain sharp cutting edges during extended machining cycles. Its spiral flute design minimizes chip buildup, reducing cutting resistance and improving surface quality. The straight shank provides versatile compatibility with a wide array of milling machines, drill presses, and CNC setups, making it a reliable choice for job shops and production environments. Use cases include enlarging existing holes to 12.07 mm with tight runout control and achieving smooth bore finishes for assemblies that require precise fit, such as bushings, pins, or bearings, across aluminum, steel, stainless steel, and other common alloys.
