Toolex Die Maker Reamer HSS-E Straight Flute SS M35 COB 5% - 12-6mm

Toolex Die Maker Reamer is a precision straight-flute reamer crafted from HSS-E (M35 cobalt) for accurate bore finishing in die-making and tooling projects. With a right-hand cut and 5% taper, it delivers controlled entry and reliable hole sizing for a wide range of materials and applications.

Designed to tight tolerances, it keeps bore and shank diameters consistent: D ±0.05 mm, d ±0.05 mm, L ±1 mm, and d1 = h8. This ensures repeatable results and easy interchangeability across jobs.

• 5% taper with tight tolerances: D ±0.05 mm, d ±0.05 mm, L ±1 mm, and d1 = h8 — delivers consistent bore size and interchangeability for repeatable results across batches.
• Straight flute design with right-hand cutting: Provides stable cutting, smooth chip evacuation, and predictable reaming action for clean, precise holes.
• HSS-E (M35 cobalt) alloy for durability: Offers excellent wear resistance and long tool life in challenging materials, reducing tool changes and downtime.

This reamer helps you achieve precise, repeatable bore finishes with minimal post-processing. It integrates seamlessly into standard machining workflows, improves throughput, and delivers reliable results on every job—so you can trust your dies, fixtures, and assemblies to fit right the first time.
