Toolex Reamer with a straight shank and spiral flute delivers precise, smooth-hole finishing for metalworking professionals. Designed for enlarging pre-drilled holes to a final 9.89 mm bore, it combines reliable performance with compatibility across common tool holders.

• Diameter: Final bore size of 9.89 mm for accurate hole enlargement and consistent finishes.
• Shank type: Straight shank compatible with a wide range of chucks, collets, and holding systems.
• Flute design: Spiral flute promotes efficient chip evacuation and reduces clogging for cleaner cuts.
• Material: HSS-E (high-speed steel with cobalt) for enhanced hardness, wear resistance, and heat tolerance.
• Construction: Cobalt-enhanced HSS-E composition supports longer tool life under demanding cutting conditions.
• Applications: Ideal for precision hole enlargement and finishing in steel, aluminum, cast iron, and other common machining materials.

With this reamer, you gain repeatable hole sizes and a smooth internal surface, enabling tight tolerances and improved fit for mating parts. The straight shank and spiral flute optimize rigidity and chip clearance, helping minimize built-up edge and heat. Use after drilling to bring holes to the exact diameter, then deburr as needed for a high-quality bore suitable for fasteners, bushings, or inserts. Designed for shops and workshops that demand dependable, consistent results across a variety of materials and machining setups.
