30mm Machine Reamer H7 Form B Right-Hand Spiral Coolant Slot Morse Taper Shank - TECWERK

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.
