Maschinenreibahle DIN 8093 H7 Form B D.8mm VHM TECWERK — Machine reamer, 8 mm, solid carbide, H7 tolerance

The Maschinenreibahle DIN 8093 H7 Form B D.8mm VHM TECWERK is a precision machine reamer designed for finishing bores to tight H7 tolerances in a production environment, suitable for use on steels, ductile iron and non‑ferrous metals.

• Solid‑carbide construction for high stiffness
• DIN 8093 standard, Form B, H7 tolerance
• Left‑hand helix for improved chip flow
• Cylindrical shank with h9 tolerance

Consistent interchangeability through precise H7 finishing

The primary advantage of this reamer is its adherence to DIN 8093 with H7 tolerance, delivering repeatable bore sizes that match standard fits. The standardised tolerance reduces downstream adjustments and minimises part rejection during assembly. Manufactured from solid carbide (VHM), the tool maintains cutting geometry under load, preserving bore geometry over longer production runs. This results in measurable savings through fewer rejects and less finishing time, a clear rational benefit for quality‑driven workshops.

Engineered cutting geometry for stable machining and chip control

A combination of right‑hand cutting with a left‑hand helix and helical flutes provides balanced cutting action and efficient chip evacuation in short‑run and serial applications. The left‑hand helix reduces vibration tendencies and helps break chips when machining materials such as steel, GGG (ductile iron) and non‑ferrous metals. The fluted design supports consistent surface finish and reduces burr formation, improving first‑pass yield — a direct performance improvement for CNC and machine tool operations.

Secure mounting and accurate tool positioning for repeat jobs

The reamer’s cylindrical shank is manufactured to a h9 shank tolerance up to 9 mm, ensuring reliable clamping in standard toolholders and collets. Stable mounting translates to improved concentricity and reduced run‑out, which is essential when aiming for tight bore tolerances. This mechanical stability is particularly relevant for shops that require consistent results across batches and want less downtime for retesting or adjustment.

Versatile application and production efficiency

Rated for use up to Ø 9.0 mm on common engineering materials, the tool is suitable for precision finishing in industries ranging from general engineering to hydraulics and small components manufacturing. The solid‑carbide design combines wear resistance with thermal stability, allowing sustained cutting performance under elevated spindle speeds and feeds. For production planners, this means fewer tool changes, extended tool life and improved overall equipment efficiency.

FAQ

What materials can be machined with this reamer?
The Maschinenreibahle DIN 8093 H7 Form B D.8mm VHM TECWERK is specified for steel, GGG (ductile iron) and non‑ferrous metals up to 9.0 mm diameter.

How does the H7 tolerance affect assembly fit?
H7 tolerance ensures consistent bore diameters that match common fit standards, so parts finished with this reamer achieve reliable interchangeability in assemblies.

Why choose solid carbide (VHM) for this reamer?
Solid‑carbide construction offers superior stiffness and wear resistance; the TECWERK VHM design maintains cutting geometry under load, extending tool life in production use.

What is the significance of the left‑hand helix?
The left‑hand helix combined with right‑hand cutting improves chip breaking and evacuation, reducing vibration and enhancing surface finish in many materials.

How should the shank be clamped for best results?
Use a collet or holder compatible with a cylindrical shank to benefit from the h9 shank tolerance and achieve low run‑out for precise bores.
