Machine reamer DIN 8093, H7, Form B, 4.5 mm — solid carbide (VHM) | TECWERK

Machine reamer DIN 8093, H7, Form B, 4.5 mm designed for precision finishing and sizing of holes in steel, ductile cast components and non‑ferrous metals with production reliability

• DIN 8093 H7 tolerance for accurate fits
• Solid carbide body for high wear resistance
• Helical flute geometry for reliable chip evacuation
• Cylindrical shank h9 for secure clamping

Accurate fits that reduce rework in production

The combination of DIN 8093 specification and H7 tolerance guarantees repeatable hole diameters and tight fits, which reduces scrap and downstream adjustment. The reamer’s 4.5 mm nominal size and standardised tolerance make it suitable for assembly tasks where predictable interference or clearance fits are required. This precision leads to fewer process retries and a steadier production flow for short runs and serial manufacturing alike.

Industrial‑grade solid carbide for sustained performance

Manufactured from VHM (solid carbide), the tool delivers high rigidity and wear resistance under regular workshop loads. Carbide construction maintains cutting geometry longer than high‑speed steels, which translates into extended tool life and stable surface finishes across multiple reaming operations. The presence of a shank tolerance h9 up to Ø 9 mm ensures reliable clamping accuracy in collets and holders, reducing run‑out and vibration during machining.

Optimised flute geometry for cleaner chips and better surfaces

The reamer is helical fluted with a left‑hand helix combined with right‑hand cutting action; this geometry promotes controlled chip evacuation and reduces heat build‑up at the cutting edge. Improved chip flow lowers the risk of built‑up edge and helps achieve a finer bore surface finish, meaning fewer manual finishing steps. The Form B profile supports consistent material removal for both finishing and sizing operations.

Practical applications and workflow advantages

Suited for machining steel, ductile iron (GGG) and a range of non‑ferrous metals up to Ø 9.0 mm, the tool is appropriate for both workshop tooling and light industrial production. Using a single, durable reamer that matches DIN standards simplifies quality assurance and reduces supplier complexity. For specialised applications, technical data and material guidance are available to ensure the correct process parameters and holder selection are applied for optimal results.

FAQ

What tolerance class does this reamer achieve?
The reamer meets H7 tolerance in accordance with DIN 8093, delivering precise hole sizing for assembly fits.

Is the tool suitable for stainless or hardened steels?
The TECWERK reamer is designed primarily for steel, ductile iron and non‑ferrous metals; suitability for stainless or hardened steels depends on specific grades and machining parameters.

Which material is the reamer made from?
The cutting tool is made from VHM (solid carbide), offering high rigidity and wear resistance for extended service life.

How does the flute design affect machining?
The helical fluted geometry with a left‑hand helix assists chip evacuation and supports improved surface finish compared with straight‑flute designs.

What clamping accuracy is recommended?
A cylindrical shank with h9 tolerance to Ø 9 mm provides secure clamping in collets and holders, helping to minimise run‑out.
