Maschinenreibahle DIN 208 H7 Form B D.25mm HSS-Co MK3 TECWERK — machine reamer for precision hole finishing A Maschinenreibahle designed to deliver high-precision holes in both blind and through applications, suitable for steel, non‑ferrous metals and plastics and finished to DIN 208 standards. HSS‑Co construction for wear resistance Tolerance H7 for consistent hole quality Morse taper shank MK3 for secure fitting Predictable, measurable hole accuracy that reduces rework The tool is engineered to produce precision holes to H7 tolerance, making it ideal where tight fits and assembly reliability matter. The 25 mm nominal diameter is reamed to the final size with predictable runout, so mating parts slide or press-fit as intended. Conformity with DIN 208 ensures compatibility with established quality criteria in industrial production. By choosing a reamer with defined geometric and tolerance characteristics the result is a measurable reduction in scrap and secondary operations, supporting faster throughput and more consistent end products. Robust alloy and mounting for uninterrupted workshop use Manufactured from HSS‑Co, the reamer offers elevated wear resistance and retained hardness under heat, which extends tool life in serial production and shop-floor environments. A Morse taper MK3 shank secures the tool in the spindle for stable, concentric running and straightforward tool changes on compatible machines. These material and mounting features together mean fewer tool swaps, less downtime and a lower cost per finished hole — advantages that translate directly into operational efficiency for machining centres and conventional lathes alike. Controlled chip removal and versatile material capability The fluting is executed as helical flutes with a left-hand helix geometry to assist chip evacuation and surface finish when reaming steel, non‑ferrous metals and plastics. For users less familiar with the terminology: the helical flute guides chips away from the cutting face and helps maintain a steady cut, while the left-hand helix optimises the direction of chip flow relative to spindle rotation. This combination reduces clogging in blind holes and improves surface quality in through holes, enabling the tool to be used across a range of common workshop materials without unpredictable variation in results. Practical setup advice for reliable results on the shop floor For consistent outcomes, the reamer should be run after accurate pre‑drilling to the recommended pilot size and kept aligned with the workpiece to avoid tool deflection. Light finishing feeds and steady spindle speeds preserve the HSS‑Co edge and protect the Form B geometry during each pass. The reamer’s design supports both hand-fed and machine applications; correct clamping with the Morse taper MK3 and adequate lubrication where appropriate will extend service life and maintain the H7 tolerance across production batches. The net benefit is fewer corrective operations and better predictability in assembly processes.

Take advantage of a tool designed for high‑precision finishing: the combination of H7 tolerance and a solid carbide cutting head delivers consistent bore accuracy and long tool life, while the Morse taper MT3 shank ensures secure seating in standard machine tool holders; order directly via Metav Werkzeuge or consult our specialists for compatibility checks. Machine reamer DIN 8094 H7 Form B, 30 mm, solid carbide, MT3 – TECWERK The machine reamer DIN 8094 H7 Form B (30 mm) is a workshop‑grade finishing tool for producing tight‑tolerance bores in a range of metals, equipped with a Morse taper MT3 shank for stable mounting Solid carbide cutting head Tolerance H7 for precision fits Morse taper MT3 shank Left‑hand helix with fluted design High‑precision finish for assembly‑ready bores The tool is engineered to achieve a H7 dimensional accuracy, which translates into reliably repeatable fits for press‑fits and bearing seats. Using a solid carbide body increases resistance to wear and thermal deformation compared with high‑speed steel alternatives, so fewer tool changes are required in continuous production. Conformity with DIN 8094 and Form B means the geometry is standardised for consistent results across batches; this standardisation reduces inspection time and supports predictable assembly tolerances. The 30 mm nominal diameter is finished to the stated tolerance by the reamer’s cutting geometry rather than by additional grinding operations, improving throughput for part runs where precision and speed are both required. Robust cutting geometry that improves process reliability A combination of right‑hand cutting with a left‑hand helix and longitudinal flutes promotes controlled chip formation and evacuation, lowering the risk of surface damage and clogging when machining ductile chips. The helical flute profile reduces vibration and distributes cutting forces more evenly, which benefits surface integrity and roundness. For workshops working with mixed batches, the reamer’s compatibility with steel, ductile iron (GGG) and non‑ferrous metals allows one tool to cover several common applications, reducing inventory complexity and downtime for tool changes. The hardy design extends tool life under typical cutting parameters while maintaining the required surface finish for final assembly. Fitment and machine compatibility for seamless integration The provision of a Morse taper MT3 shank enables stable, repeatable seating in conventional spindles and tailstocks, allowing the reamer to be used on both conventional and CNC machines without special adaptors. Because the seating is standardised, runout is minimised and concentricity is improved, which in turn preserves the tolerance across the length of the bore. The tool’s construction and form factor are suitable for routine workshop toolholders and reaming sleeves that accept MT3 mounting; this makes tool changeover straightforward and helps maintain machine uptime. Where higher rigidity is required, the solid‑carbide body contributes to stiffness and consistent cutting behaviour. Practical advantages for procurement and workshop planning Specifying a standardised reamer compliant with DIN 8094 simplifies quality documentation and supplier audits, since geometry and tolerance expectations are clear. The use of a solid carbide cutting head reduces the frequency of reconditioning cycles and lowers long‑term tooling expenditure through extended life and predictable wear patterns. The flute and helix design reduce manual deburring and rework, supporting higher first‑pass yields. For operations transitioning from HSS to carbide reamers, attention to cutting parameters and lubrication will unlock the potential for faster cycle times and improved surface quality without sacrificing dimensional accuracy.
