Toolex Die Maker Reamer HSS-E Straight Flute SS M35 COB 10% - 8-3mm

Toolex Die Maker Reamer is a straight-flute HSS-E reamer (M35 COB) designed for die-making and precision hole finishing. It features a 10% taper and right-hand cut, delivering stable, accurate holes in demanding materials for consistent production outcomes.

Engineers, machinists, toolmakers, and serious hobbyists rely on this reamer for precise sizing and reliable, repeatable performance in production environments.

• Durable HSS‑E M35 COB construction: Built from cobalt-enhanced high-speed steel for extended tool life and reliable cutting in tough materials, reducing tool changes.
• 10% taper with straight flute: Promotes smooth entry, reduces rubbing, and yields clean, accurate holes with straightforward chip evacuation.
• Precise tolerances for repeatable results: D = ±0.05 mm, d = ±0.05 mm, L = ±1 mm, d1 = h8 ensure consistent hole size and interchangeability in die making and precision machining.

This reamer helps you achieve precise, repeatable hole sizes with smooth finishes, boosting assembly fit and overall machining accuracy. The hard-wearing HSS‑E steel stands up to demanding materials, while tight tolerances minimize rework and reduce downtime across production runs. With a 10% taper, straight flute, and right-hand cutting, you get reliable performance from the first hole to the last, streamlining setup and delivering consistent results.
