Toolex Reamer with a straight shank and spiral flute delivers precise hole enlargement and finishing for machinists and fabrication shops seeking repeatable accuracy. Built from HSS-E for durability and heat resistance, this 12.28 mm reamer is designed for reliable, long-lasting performance across a range of materials.

• Diameter: 12.28 mm
• Shank type: Straight shank for broad compatibility with common tool holders and collet chucks
• Flute design: Spiral flutes promote efficient chip evacuation and smoother cutting
• Material: HSS-E (high-speed steel with cobalt) for enhanced hardness and heat resistance
• Application: Ideal for precision hole enlargement and finishing in numerous materials
• Accuracy: Delivers precise, smooth holes with tight, repeatable tolerances

These reamers help you achieve consistent hole sizes, enabling proper fits for bushings, shafts, and assemblies. The cobalt-infused HSS offers better heat resistance during deeper or more aggressive cuts, extending tool life. The straight shank ensures flexible mounting across CNC mills and manual machines, while the spiral flute design minimizes chip buildup for steady cutting action. For best results, pair with proper coolant and maintain appropriate speeds and feeds to preserve surface finish and dimensional accuracy.
