Toolex Die Maker Reamer HSS-E Straight Flute SS M35 COB 8% - 10-4mm

Toolex Die Maker Reamer HSS-E Straight Flute is a precision reamer designed for die and mold work. Built from HSS-E with M35 cobalt content, it delivers durable wear resistance for repetitive reaming tasks while maintaining predictable performance. The right-hand cut and straight flute simplify setup and feeding in common machining setups.

With an 8% taper along the length, this reamer produces consistent hole sizes and clean finishes. Its defined tolerances ensure repeatable results: hole diameter D ± 0.05 mm, shank diameter d ± 0.05 mm, overall length L ± 1 mm, and d1 = h8.

• 8% taper with straight flute: The tapered design guides the tool cleanly and the straight flute promotes easy chip clearance, resulting in consistent hole quality and reduced taper variation.
• HSS-E (M35 COB) construction: Cobalt-enhanced high-speed steel offers improved wear resistance and heat tolerance, extending tool life in demanding die-making materials and reducing tool changes.
• Tight, verifiable tolerances: Precise dimensional control — D ± 0.05 mm, d ± 0.05 mm, L ± 1 mm, and d1 = h8 — to deliver repeatable fits and dependable alignment in assemblies.

When you choose this reamer, you gain a reliable finishing step that improves hole quality, reduces rework, and speeds up your die and mold production workflow. The combination of durable HSS-E material, controlled taper, and tight tolerances translates into longer tool life, consistent measurements, and confidence in every part you produce.
