The Toolex Reamer with a straight shank and spiral flute is a precision tool built for machinists and fabrication shops that require clean, accurate hole enlargement and finishing. Crafted from HSS-E, it combines durability with reliable heat resistance to deliver consistent bore quality across a range of materials.

• Diameter: 4.88 mm
• Shank Type: Straight shank for broad compatibility with common toolholding systems
• Flute Design: Spiral flute for efficient chip evacuation and smoother cutting
• Material: HSS-E (high-speed steel with cobalt) for enhanced hardness and heat resistance
• Applications: Precision hole enlargement and finishing with consistent bore quality
• Performance: Maintains tight tolerances and smooth bore finishes over repetitive uses

This reamer helps you achieve exact hole diameters in a single setup, supporting precise mating fits and reliable assembly alignment. The spiral flute minimizes chip buildup, boosting cutting efficiency and reducing the risk of burrs or drill-induced damage. Its straight shank design ensures straightforward clamping in standard toolholders, enabling quick Tooling changes in busy shops. The cobalt-enhanced HSS construction stands up to heat and wear, extending tool life when reaming stainless steel, alloy steels, aluminum, and other common metals. Ideal for refurbishing pre-drilled holes, final sizing, and finishing operations that demand tight tolerances and a smooth, consistent bore.
