Toolex Reamer with a straight shank and spiral flute offers precision hole enlargement and finishing in a reliable, easy-to-integrate format. Designed for machinists and shops that demand consistent, smooth holes, it pairs robust HSS-E cobalt construction with a geometry that delivers real-world performance across materials.

• Nominal diameter: 12.41 mm – delivers precise hole enlargement and tight tolerances in finished work.
• Material and construction: HSS-E (high-speed steel with cobalt) for enhanced hardness, wear resistance, and heat tolerance during demanding cuts.
• Flute design: Spiral flute enables efficient chip evacuation, reduces chip buildup, and supports stable, clean cutting action.
• Shank type: Straight shank for straightforward clamping in a wide range of toolholding systems, including collets and chucks.
• Applications: Ideal for precision hole enlargement and finishing in a variety of metals, from softer alloys to tougher steels.

This reamer helps you achieve smooth bore finishes and consistent diameters across repeated operations, minimizing post-process finishing. The combination of spiral flutes and cobalt-enhanced steel keeps cutting temperatures manageable and supports longer tool life, even in tougher materials. Its straightforward shank design means quick setup across drilling machines, mill centers, and CNC equipment, making it a dependable choice for precision drilling workflows, repair work, and final-hole sizing tasks.
