Toolex Reamer with a straight shank and spiral flute is a precision cutting tool designed for professionals who need to enlarge or finish holes to exact tolerances. Made from HSS-E (high-speed steel with cobalt), it delivers durable performance and heat resistance across a range of materials.

• Diameter: 3.83 mm nominal cutting size for precise hole enlargement and finishing
• Material: HSS-E (high-speed steel with cobalt) for increased hardness and heat resistance, extending tool life
• Flute Design: Spiral flute optimizes chip evacuation for smoother cuts and reduced chip buildup
• Shank: Straight shank compatible with a wide range of tool-holding systems and fixtures
• Accuracy & Finish: Engineered to deliver consistent hole sizes with a clean, smooth surface finish across multiple passes
• Applications: Suitable for enlarging existing holes and achieving precise diameters in steel, cast iron, and nonferrous alloys

By choosing the Toolex spiral-flute straight-shank reamer, you gain dependable performance that supports repeatable manufacturing outcomes. The spiral flute enhances chip clearance, helping prevent clogging and heat buildup, while the cobalt-infused HSS achieves longer life under demanding cutting conditions. The straight shank offers flexible mounting in milling machines, drill presses, and CNC setups, reducing setup time and enabling quick changes between operations. For hole finishing or size dialing, this reamer maintains tight tolerances and delivers a consistently smooth bore that reduces post-processing work.
