Machine reamer DIN 208 H7 Form B 28 mm — TECWERK (HSS‑Co, MK3 shank)

Machine reamer DIN 208 H7 Form B 28 mm — TECWERK is a purpose‑built reaming tool for accurate finishing of blind and through holes in steel, non‑ferrous metals and plastics, intended for use in machine spindles with an MK3 Morse taper.

• DIN 208 standard, H7 tolerance
• Cobalt HSS for increased wear resistance
• Morse taper MK3 shank for secure mounting
• Helical flutes with left‑hand helix

Consistent hole quality with tight tolerances

The reamer follows DIN 208 and is ground to an H7 tolerance, delivering predictable diameters and repeatable fits. Thanks to the HSS‑Co composition, the tool sustains cutting edge integrity under demanding conditions, which reduces rework and scrap rates. This results in measurable quality gains in batch production and supports efficient assembly processes where hole accuracy is critical.

Reliable cutting in a range of materials

Designed for both blind and through holes, the reamer works effectively in steel, non‑ferrous metals and plastics. The combination of right‑hand cutting geometry and helical flutes with a left‑hand helix enhances chip formation and evacuation, improving surface finish and reducing clogging in interrupted cuts. Such characteristics make the tool suitable for mixed‑material workshops and machining centres where versatile performance is required.

Stable mounting and productive machining cycles

The Morse taper (MK3) shank offers secure seating in standard machine spindle adaptors, lowering radial runout and improving concentricity during reaming operations. The tool’s Form B configuration supports machine mounting and straightforward changeovers, shortening set‑up times and increasing spindle utilisation. For production environments seeking consistent throughput, the combination of stable clamping and wear‑resistant material contributes to longer service intervals and predictable tool life.
