Toolex Reamer with a straight shank and spiral flute delivers precise hole enlargement and finishing for machinists and fabrication shops. Made from HSS-E (high-speed steel with cobalt), it combines outstanding durability with heat resistance for consistent, accurate results in a wide range of materials.

• Diameter: 5.51 mm nominal cutting diameter for accurate hole sizing and tight tolerances.
• Shank geometry: Straight shank designed for reliable grip in common tool-holding systems, offering straightforward setup and compatibility with CNC and manual machines.
• Flute design: Spiral flute enables efficient chip evacuation, reducing chip buildup and promoting smooth cutting action.
• Material: HSS-E (high-speed steel with cobalt) provides enhanced hardness and heat resistance for longer tool life in demanding materials.
• Applications: Ideal for enlarging existing holes and finishing to a precise diameter with clean, burr-free results.
• Performance: Delivers consistent, accurate hole quality across production runs and a wide range of materials.

These features translate into real-world benefits: you get repeatable hole sizes, better surface finish, and reduced rework. The straight shank makes it easy to drop into standard chucks and holders, while the cobalt-enhanced steel stands up to higher cutting speeds and longer runs. Whether you’re finishing drilled holes in steel, aluminum, cast iron, or other alloys, this Toolex reamer is a dependable choice for precise, smooth results.
