Machine reamer DIN 8093 H7 Form B, 6 mm (solid carbide) – TECWERK

The Machine reamer DIN 8093 H7 Form B, 6 mm is a precision finishing tool for producing accurate, H7‑class holes in steel, spheroidal graphite cast iron and non‑ferrous metals up to 9.0 mm.

• DIN 8093, Form B with H7 tolerance
• Solid carbide (VHM) for high rigidity
• Spiral flutes with left‑hand helix
• Cylindrical shank h9 up to Ø9 mm

Accurate hole tolerance for repeatable assembly fits

The reamer delivers an optimised fit class by machining to H7 tolerance, ensuring repeatable clearances for bearings, dowels and press fits. The adherence to DIN 8093 provides a standardised basis for interchangeability, reducing the need for trial adjustments. With a nominal diameter of 6 mm, the tool is intended for finishing pre‑drilled bores to the required tolerance grade; this controlled material removal improves concentricity and surface integrity compared with rough drilling alone.

Robust solid‑carbide construction for stability and tool life

Constructed from solid carbide (VHM), the tool combines stiffness and wear resistance for extended tool life under continuous use. Carbide substrate offers thermal stability at elevated cutting speeds and maintains cutting geometry over many cycles, which lowers replacement frequency and contributes to predictable process costs. The solid‑carbide design also minimises deflection, delivering a stable cutting action that translates into fewer rejects and less rework.

Spiral flutes and left‑hand helix for improved chip control

The helical flute geometry with a left‑hand helix optimises chip formation and evacuation during finishing passes. In combination with a right‑hand cutting direction, this helix orientation helps lift chips away from the bore while preserving surface finish, particularly in ductile materials. The spiral flutes promote continuous chip flow, reducing the risk of clogging and heat buildup; as a result, the finished holes show improved micro‑finish and dimensional consistency.

Precise shank tolerance and easy integration into toolholders

A cylindrical shank with tolerance h9 up to Ø9 mm provides accurate seating in collets and holders, reducing runout and ensuring the reamer runs true. The Form B specification and the shank tolerance support straightforward integration into standard machine setups, enabling short changeover times and consistent alignment. Compatibility with common holders simplifies tooling logistics and helps maintain machining throughput in production environments.

FAQ

What materials can this reamer machine for?
The TECWERK machine reamer is suitable for finishing in steel, spheroidal graphite cast iron (GGG) and non‑ferrous metals up to Ø 9.0 mm.

Does the tool meet a specific standard for tolerance?
Yes, the tool is manufactured to achieve H7 tolerance in accordance with DIN 8093, ensuring standardised hole fits.

What is the shank tolerance and why does it matter?
Shank tolerance is h9 up to Ø9 mm; this accuracy ensures reliable seating in collets and reduces runout during machining.

How does the left‑hand helix affect performance?
The left‑hand helix combined with right‑hand cutting improves chip evacuation and helps maintain surface finish during through‑hole reaming.

Is the cutting material suitable for high‑speed finishing?
The solid‑carbide (VHM) construction provides thermal and geometric stability that supports higher cutting speeds and extended tool life.
