Machine reamer DIN 8093 H7, Form B, Ø 9 mm – solid carbide (TECWERK) The Machine reamer DIN 8093 H7, Form B, Ø 9 mm – solid carbide (TECWERK) provides precision reaming for small-diameter holes where tight tolerances and consistent surface quality are required across steel, GGG and non‑ferrous materials DIN 8093 H7 tolerance for tight fits Solid carbide for high rigidity Left-hand helix with spiral flutes Cylindrical shank tolerance h9 Precision finishing for reliable fits Designed to meet DIN 8093 with an H7 tolerance, this precision reamer guarantees repeatable hole sizes at Ø 9 mm, making it suitable where tight fits and dimensional reliability are essential. The H7 tolerance is a standard industrial fit class that offers predictable clearances for assembly; choosing a tool manufactured to this standard reduces rework and downstream alignment issues. The specification-driven design supports process planning and quality control efforts, helping maintain consistent part acceptance rates in production environments. Robust solid carbide construction for consistent performance Built from solid carbide, the reamer delivers high rigidity and wear resistance, which translates into stable cutting behaviour and extended tool life when used under appropriate conditions. A cylindrical shank with tolerance h9 ensures accurate seating in collets or chucks, improving concentricity and reducing runout. These attributes combine to lower scrap rates and reduce machine downtime, representing an economically sound choice for workshops and small-series production where tool reliability and consistent finishing quality are priorities. Optimised geometry for chip control and surface quality The cutting geometry combines right-cutting edges with a left-hand helix and spiral flutes to promote effective chip evacuation while preserving the reamed surface. This arrangement aids in directing swarf away from the cutting zone, which reduces risk of surface damage and supports a fine internal finish. The tool’s Form B profile is geared towards finishing operations where dimensional stability and surface integrity are both required; the spiral fluting provides a balance between gentle cutting action and efficient material removal. Applications and handling that support production needs Suitable for machining steel, spheroidal graphite cast iron (GGG) and non-ferrous metals up to Ø 9.0 mm, the reamer is well matched to common workshop tasks such as final-size holes for dowels, pins and precision fasteners. For best results, secure workholding and correct alignment are essential; the shank tolerance promotes reliable clamping, while appropriate cutting fluid and machine rigidity will extend tool life. The combination of standard compliance and robust materials makes this reamer a practical choice for industrial and toolroom applications requiring predictable finishes.

Take advantage of HSS‑Co construction and tolerance H7 to secure consistent fitment and minimal rework. The combination of spiral fluting and unequal pitch reduces chatter while the cylindrical shank ensures stable clamping in precision holders; order the reamer directly via Metav Werkzeuge or consult our specialists for process integration. NC machine reamer DIN 212-3 H7, Ø 9 mm – HSS‑Co (TECWERK) A NC machine reamer DIN 212-3 H7 Form B Ø 9 mm (HSS‑Co) by TECWERK for finishing base and through holes in steel, spheroidal graphite cast iron (GGG) and non‑ferrous metals. HSS‑Co for high wear resistance Tolerance H7 for repeatable fits Spiral flutes with left‑hand helix Cylindrical shank for secure clamping Achieve precise, repeatable fits for assemblies The reamer is built from HSS‑Co, a high‑cobalt high‑speed steel alloy that maintains cutting edge stability under heat, which directly reduces the need for rework and extends tool life. Its H7 tolerance is engineered for precision fit‑up, delivering consistent clearance and allowing predictable assembly of shafts and housings. For production environments this translates into fewer rejected parts and tighter process control, supporting throughput and quality targets. Stable cutting and reduced chatter for smoother finishes A combination of spiral flutes and unequal pitch actively reduces harmonic vibration during reaming, improving surface finish and dimensional stability. The left‑hand helix together with a right‑hand cutting geometry promotes effective chip formation and evacuation in through‑hole operations. As a result, the tool produces smoother bore surfaces and lowers the risk of built‑up edge, which is especially beneficial when machining mixed batches of steels and non‑ferrous alloys. Designed for demanding materials and hole types Specified to DIN 212‑3 and supplied in Form B, this reamer is suitable for both base (blind) and through holes in common engineering materials such as steel, GGG (spheroidal graphite cast iron) and non‑ferrous metals. The material compatibility and robust geometry enable its use in series production and toolrooms where component integrity matters. Where intermittent hard spots occur, the cobalt alloy helps maintain cutting performance over longer runs. Integration into precision processes for increased process security A cylindrical shank allows secure clamping in standard NC toolholders, and the tool is expressly suitable for use with hydro expansion, high‑precision collets or shrink‑fit holders to achieve superior run‑out accuracy. This compatibility is key for applications that demand tight concentricity and repeatability. Incorporating this reamer into a controlled tooling system reduces downtime, simplifies tool change routines and supports traceable manufacturing results.
