Toolex Reamer with a straight shank and spiral flute combines precision, durability, and versatility for finishing and enlarging holes. Designed for machinists and metalworkers, it delivers smooth, accurate bore finishes at a consistent diameter.

• Diameter: 4.78 mm
• Material: HSS-E (high-speed steel with cobalt) for exceptional wear resistance and heat tolerance
• Flute design: Spiral flutes optimize chip evacuation and reduce cutting resistance
• Shank type: Straight shank compatible with a wide range of tool-holding systems
• Precision and consistency: Engineered for accurate hole sizes and repeatable finishes
• Applications: Ideal for enlarging and finishing holes in steels, aluminum, brass, and cast iron
• Machining compatibility: Suitable for standard CNC and manual setups with common collets and chucks

When you need a clean, precise bore, this reamer maintains tight tolerances across multiple passes and materials. The cobalt-infused HSS enhances durability under heat, prolonging tool life even in demanding finishing operations, while the spiral flute design minimizes chip buildup for smoother cuts and steadier feeds. The straight shank ensures reliable, repeatable holding across different machines and rigs, making it a dependable choice for both workshop benches and production environments.
