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

Toolex Die Maker Reamer is a precision HSS-E reamer designed for die and mold work. Crafted from cobalt-enriched HSS (M35), it delivers enhanced wear resistance for demanding reaming tasks. The spiral flute and 10% taper provide controlled material removal and a smoother entry, while the right-hand cutting direction ensures predictable performance in standard die-making operations.

Designed for reliability in production settings, this reamer helps you achieve consistently sized holes with tight tolerances, reducing rework and improving die alignment. It’s a durable, ready-to-use tool that performs under the stresses of repetitive machining.

• 10% taper with spiral flute: Provides controlled material removal and a smoother entry, helping achieve accurate hole sizes and clean finishes in each reaming pass.
• HSS‑E with M35 cobalt composition: Delivers enhanced hardness and wear resistance for longer tool life, especially when reaming tougher metals and hardened dies.
• Exact tolerances: D ±0.05 mm, d ±0.05 mm, L ±1 mm, with d1 = h8 for repeatable hole size and reliable fits across production runs.

With this reamer, you’ll achieve precise hole diameters in dies, improving alignment and reducing rework, while the robust HSS-E material provides dependable performance and longer tool life under continuous use.
