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.

FAQ

What tolerance class does this reamer achieve?
The TECWERK machine reamer is manufactured to DIN 8093 and achieves an H7 tolerance class for Ø 9 mm holes, suitable for standard precision fits.

Which materials can be machined with this tool?
The reamer is intended for steel, spheroidal graphite cast iron (GGG) and non‑ferrous metals up to Ø 9.0 mm, as specified for the solid carbide design.

How does the left‑hand helix affect cutting?
The left‑hand helix combined with right‑cutting edges and spiral flutes promotes chip evacuation and supports a smooth internal surface, reducing the likelihood of rework.

Is the shank compatible with common collets and chucks?
Yes; the cylindrical shank is produced to h9 tolerance to ensure accurate seating in standard collets and chucks for improved concentricity.

What benefits does solid carbide provide for reaming?
Solid carbide offers high rigidity and wear resistance, which helps maintain dimensional accuracy and extend service life under consistent operating conditions.
