The Toolex Reamer with a straight shank and spiral flute delivers precise enlargement and a smooth finish for 0.68mm holes. Built for engineers, machinists, tradespeople, hobbyists, and shop environments, it provides reliable, repeatable results across a range of materials and setups. Crafted from HSS-E (high-speed steel with cobalt), it combines durability and heat resistance for longer tool life. The spiral flute design promotes efficient chip evacuation, reducing buildup and maintaining stable cutting performance, while the straight shank ensures compatibility with a wide variety of tool holders. Spiral flute for efficient chip evacuation: The spiral design clears chips quickly, reducing packing and delivering smoother, more accurate hole enlargements. HSS-E cobalt steel construction: Combines hardness with enhanced heat tolerance for longer life and consistent performance on demanding materials. Straight shank for versatile tool holding: Fits a broad range of machine quills and collet systems, enabling easy mounting across different setups. This reamer helps you achieve precise, repeatable hole sizes with minimal downtime. The durable build stands up to regular use in demanding environments, while efficient chip evacuation maintains steady cutting action, resulting in cleaner finishes and tighter tolerances. With broad material compatibility and straightforward mounting, it supports a smoother, faster workflow from setup to finished part.
