Machine reamer DIN 8093 H7, Form B, 14 mm — TECWERK

A Machine Reamer DIN 8093 H7, Form B, 14 mm designed for high‑precision finishing of bores in steel, spheroidal graphite cast iron and non‑ferrous metals using carbide cutting inserts.

• DIN 8093 tolerance H7
• Carbide cutting inserts
• Spiral-fluted with left-hand helix
• Cylindrical shank, shank tolerance h6

Consistent hole accuracy for series production

The reamer is engineered to meet DIN 8093 requirements and to achieve H7 tolerance, which ensures repeatable hole diameters within tight limits. Such accuracy reduces subsequent machining or inspection effort, improving throughput in batch production. The combination of carbide cutting inserts with a stable cutting geometry delivers longer tool life and predictable wear behaviour, making the tool suitable where dimensional conformity is essential.

Reliable chip control and cutting behaviour

The spiral‑fluted design with a left‑hand helix promotes controlled chip evacuation and reduces surface damage during reaming. Despite the left‑hand helix, the tool is right‑hand cutting, which preserves conventional spindle direction in most machines while benefitting from improved chip flow. This geometry helps maintain bore roundness and surface finish, especially important when working with mixed material batches or longer bore depths.

Robust interface and secure clamping

A cylindrical shank with h6 tolerance from 10 mm provides a precise, vibration‑resistant connection to the machine tool holder. The stated shank specification contributes to concentric clamping and minimises run‑out, which in turn supports the achievement of the specified H7 tolerance at the finished bore. The tool is intended for use from Ø 10.0 mm (compatible with shank tolerance) and is ready to integrate into standard production setups.

Material suitability and application range

The geometry and insert grade make the tool appropriate for steel, GGG (spheroidal graphite cast iron) and non‑ferrous metals, covering common workshop and industrial applications. Carbide inserts maintain cutting performance across those materials and offer an economical alternative to full‑body carbide where indexable cutting edges are preferred. The Form B specification denotes the tool’s design under DIN and supports straightforward part replacement and tool management in a production environment.

FAQ

Which materials can be machined with this reamer?
The TECWERK machine reamer is specified for steel, GGG (spheroidal graphite cast iron) and non‑ferrous metals, making it suitable for mixed‑material production where consistent finish is required.

What does H7 tolerance mean for bore quality?
H7 denotes a standard hole tolerance band under DIN/ISO; in practice the H7 tolerance of this tool ensures reproducible hole diameters with a snug fit for many engineering applications.

Is the shank compatible with standard collets?
Yes — the tool features a cylindrical shank with h6 tolerance from 10 mm, designed to fit standard holders and minimise run‑out for accurate finishing.

Are the cutting inserts replaceable?
The design uses carbide cutting inserts, which are replaceable; this enables economical maintenance and consistent cutting performance without replacing the entire tool body.

What design aspects improve chip evacuation?
The spiral‑fluted profile combined with a left‑hand helix promotes effective chip flow and reduces the risk of surface marking in the bore.
