TECWERK Machine reamer DIN 208 H7 Form B, 22 mm — HSS‑Co, Morse taper MK2

The TECWERK machine reamer DIN 208 H7 Form B is a high-precision tool for finishing blind and through holes in metals and plastics, designed for machine mounting with a Morse taper shank

• HSS‑Co for extended tool life
• Tolerance H7 for precision holes
• Spiral flutes for reliable chip evacuation
• Morse taper MK2 for secure machine mounting

Achieve repeatable, tight bore tolerances for production parts

The combination of DIN 208 geometry and H7 tolerance delivers repeatable hole sizes that reduce downstream rework and ensure interchangeability of mating components. The tool is built for precision, limiting bore deviation and aiding quality control processes where tolerances matter. Using a dedicated reamer for final sizing removes the variability of multi‑step drilling sequences and supports consistent assembly performance in batch production.

Robust material and coating for longer tool life under load

Manufactured from HSS‑Co (cobalt‑enriched high‑speed steel), the cutter resists softening at elevated cutting temperatures, providing superior wear resistance compared with standard high‑speed grades. This material choice extends service intervals and keeps dimensional stability over longer runs. In practice, the cobalt content increases red hardness, which is especially beneficial when reaming harder steels or when intermittent heavy cuts are required.

Spiral flutes designed for efficient chip control and surface finish

The spiral flutes guide chips away from the cutting edges, reducing clogging in blind holes and supporting a stable cutting action that improves surface finish. The combination of right‑hand cutting geometry with spiral fluting balances cutting forces and helps avoid chatter on rigid machine setups. As a result, the final bore often requires little or no deburring, accelerating downstream operations and improving overall process efficiency.

Machine compatibility and application versatility for workshop use

Equipped with a Morse taper (MK2) shank, the reamer seats securely in standard machine spindles for repeatable concentricity and quick tool changes. Suitable materials include steel, non‑ferrous metals and plastics, making the tool versatile across maintenance, prototyping and small‑series production. The Form B configuration supports both through and blind hole finishing, giving flexibility for diverse machining tasks without compromising accuracy.
