Machine reamer DIN 8094 H7 Form B, 20 mm — solid carbide, MK2 (TECWERK)

The Machine reamer DIN 8094 H7 Form B, 20 mm is a carbide machine reamer engineered for precision finishing of holes in a range of metals, combining standard-compliant tolerances with a Morse taper shank for reliable mounting.

• Solid carbide, DIN 8094 H7
• Form B geometry for stable finishing
• MK2 Morse taper shank for secure mounting
• Helical flutes with left-hand helix
• Suitable for steel, ductile iron and non‑ferrous metals

Accurate hole finishing for reliable assembly performance

The reamer adheres to DIN 8094 and delivers H7 tolerance results for repeatable hole diameters, making it suitable where consistent fits are essential. The 20 mm nominal size provides a predictable finished bore, reducing the need for secondary sizing operations and lowering rejection rates. By relying on a standardised tolerance class, process planners and quality engineers gain clarity on achievable fits and can integrate the tool within established SPC workflows to preserve assembly tolerances and minimise stoppages.

Carbide grade and flute design that stabilise cutting and chip evacuation

Constructed from solid carbide, the tool offers high edge stability and wear resistance for extended service life on production runs. The Form B geometry supports controlled allowances and a smooth surface finish, while the helical flutes with a left-hand helix are matched with right-hand cutting to optimise chip flow away from the cutting zone. This combination reduces the risk of clogging and helps to mitigate vibration in machine-mounted reaming, delivering a cleaner bore and prolonging cutter life with fewer interruptions for cleaning or inspection.

Secure mounting and broad material compatibility for shop-floor flexibility

The Morse taper MK2 shank enables a solid machine mounting that resists axial pull and runout when seated correctly, improving concentricity and surface quality during reaming. The tool is specified for common engineering substrates — steel, ductile iron and non‑ferrous metals — allowing a single cutter to service multiple production tasks without frequent tool changes. Its specification supports use in machine-tools equipped for precision reaming, and its robustness makes it suitable for both short batch and continuous production contexts where consistent hole quality is required.
