Toolex Die Maker Reamer HSS-E Straight Flute SS M35 COB 5% - 10-5mm

The Toolex Die Maker Reamer is a straight-flute HSS-E reamer (M35 cobalt) designed for precision hole finishing in die making, tooling, and metalworking. It’s built for machinists, toolmakers, and workshop environments that require accurate hole sizing with durable performance.

With a 5% taper and right-hand cut, it starts cleanly and maintains a smooth, consistent bore finish, helping you achieve reliable results with fewer rework steps.

• Durable HSS‑E with cobalt alloy: Made from HSS‑E (M35 cobalt) for improved wear resistance, delivering longer tool life in repeated reaming cycles.
• 5% taper with straight flute for consistent finish: The taper aids easy entry while the straight flute promotes stable cutting and a clean bore with minimal chatter.
• Precise tolerances you can trust: Tolerances are D ±0.05 mm, d ±0.05 mm, L ±1 mm, and d1 = h8, ensuring hole size and overall length meet tight, repeatable specifications.

This reamer helps you achieve accurate hole sizing and smooth finishes across die-making and metalworking workflows. The cobalt-rich substrate resists wear for longer service life, while the defined tolerances reduce variation between parts, enabling more consistent assemblies and faster production cycles.
