TECWERK NC machine reamer DIN 212-3 · H7 · 16 mm · HSS-Co

The TECWERK NC machine reamer designed for precision finishing of blind and through holes in steels, ductile cast iron and non‑ferrous metals.

• Cobalt high-speed steel (HSS-Co) construction
• Tolerance H7 for precision fits
• DIN 212-3, Form B geometry
• Cylindrical shank with helical flutes

Consistent precision for reproducible fits

The reamer is engineered to deliver consistent tolerances thanks to its H7 specification and DIN 212-3 geometry. The combination of Form B cutting geometry and HSS‑Co material reduces thermal distortion during operation, which supports stable dimensional results across production runs. For users requiring predictable clearances and repeatable assemblies, this finishing tool reduces the need for secondary sizing operations by producing accurate bores ready for immediate use.

Designed for NC machining and high process reliability

Optimised for numerical control machines, the tool features a cylindrical shank and an arrangement of helical flutes with unequal spacing to smooth chip flow and minimise vibration. The reamer’s right‑hand cutting with a left‑hand helix promotes controlled cutting forces and helps to preserve surface quality. When combined with hydraulic expanding chucks, high‑precision collets or shrink‑fit holders, the tool contributes to exceptionally low runout and enhanced process reliability, making it a practical choice for demanding production environments.

Broad material compatibility and operational benefits

Suitable for finishing both blind and through holes in steel, GGG (ductile cast iron) and non‑ferrous metals, the reamer offers versatility across common workshop and industrial tasks. The cobalt alloy base provides improved hot‑hardness and wear resistance compared with standard high‑speed steels, extending tool life under elevated cutting temperatures. The unequal flute spacing reduces harmonics, improving surface finish and reducing the frequency of tool changes — a tangible efficiency gain in medium to high volume production.

Practical handling and integration in production

The tool’s specifications, including its 16 mm nominal diameter and cylindrical shank, allow straightforward integration into standard NC toolholders and automated tool changers. Unequal flute spacing and the specific Form B geometry support reliable chip evacuation and better surface integrity, which lowers the incidence of rework. For workshops consolidating tooling supplies, the reamer complements existing setups where precision finishing and repeatable fits are required.
