Toolex Die Maker Reamer HSS-E Spiral Flute SS M35 COB 10% - 12-5mm

The Toolex Die Maker Reamer is a precision finishing tool designed for hole finishing in die-making, mold work, and general metalworking. Crafted from HSS-E with M35 cobalt, it delivers exceptional wear resistance and long tool life in tough materials, making it a reliable choice for engineers, machinists, toolmakers, and hobbyists who demand consistent bore quality.

This right-hand cutting reamer features a 10% taper and a spiral flute, delivering smooth cutting and efficient chip evacuation to help you achieve accurate hole sizes with minimal chatter.

• HSS-E with M35 cobalt alloy: Delivers superior hardness and wear resistance for longer tool life and consistent results when working with hardened steels and challenging alloys.
• 10% tapered spiral geometry: Provides controlled material removal and precise bore dimensions (D ±0.05 mm, d ±0.05 mm), reducing over- and under-size holes for reliable fits.
• Spiral flute with right-hand cut: Encourages efficient chip evacuation and a smooth bore finish, enabling predictable cutting performance across a range of materials.

By using this reamer, you achieve faster setup-to-finish cycles, fewer reworks, and reliable hole quality that supports precise assembly and longer-lasting tooling. The defined tolerances (D = ±0.05 mm, d = ±0.05 mm, L = ±1 mm, d1 = h8) ensure you meet tight specifications consistently, making it a dependable choice for professional shops and serious hobbyists alike.
