Toolex Die Maker Reamer HSS-E Straight Flute SS M35 COB 5% - 14-7mm

Toolex Die Maker Reamer is a precision HSS-E straight-flute reamer designed for die making, tooling, and precision bore finishing. It uses a cobalt-enhanced HSS-E substrate (M35 COB) to deliver improved wear resistance and long tool life in demanding materials, making it a reliable choice for engineers, machinists, and workshop enthusiasts alike.

• 5% taper for guided entry and smooth finishes: The gradual taper helps align the reamer with the bore, reducing runout and delivering consistent hole size and a clean surface in die-form work.
• Tight tolerance control: Engineered to maintain hole diameters with D ± 0.05 mm, bore diameter d ± 0.05 mm, length L ± 1 mm, and d1 = h8, supporting repeatable results across production runs.
• HSS-E with M35 cobalt for long wear life: The cobalt-enriched substrate provides superior hardness and wear resistance, helping the tool hold its accuracy even in tough materials.

This reamer supports reliable, consistent bore finishing, reducing secondary polishing and rework while fitting seamlessly into standard reaming setups. It helps improve workflow efficiency and delivers repeatable results across dies, molds, and precision components.
