TECWERK NC machine reamer DIN 212-3 H7, Form B, 10 mm, HSS‑Co

The TECWERK NC machine reamer DIN 212-3 H7 Form B 10 mm HSS‑Co is a precision machine reamer for finishing blind and through holes in steel, ductile cast iron and non‑ferrous metals.

• HSS‑Co for extended tool life
• DIN 212‑3 tolerance H7
• Left‑hand helical flutes, unequal spacing
• Cylindrical shank for secure clamping

Consistent tolerance and superior surface finish

The reamer provides repeatable bore dimension control through its DIN 212‑3 specification and H7 tolerance, ensuring interchangeability of mating parts. Manufactured from HSS‑Co, the tool sustains cutting edges at elevated temperatures and offers improved wear resistance compared with standard HSS. This results in a stable surface finish and consistent diameter retention over production runs, reducing rework and scrappage rates. Where high accuracy is required, the geometry is optimised to deliver predictable material removal and final size.

Adaptable to common engineering materials

Engineered for versatility, the tool is suitable for steel, ductile cast iron and a range of non‑ferrous metals, covering the typical spectrum of workshop and production requirements. The left‑hand helical flute design with unequal flute spacing reduces vibration and promotes chip control during finishing passes, which is particularly helpful when reaming blind holes. The combination of material compatibility and flute geometry makes the tool appropriate for small‑batch prototyping as well as medium‑volume series production.

Geometry and clamping for process reliability

A cylindrical shank and right‑hand cutting direction provide straightforward integration with standard machining spindles and fixtures. For optimal runout accuracy and maximum process security, pairing the reamer with hydro expansion fittings, high‑precision collets or shrink holders is recommended; this minimises radial runout and ensures the required bore quality. The result is stable, repeatable performance and lower setup times, supporting efficient workflow in CNC machining environments.
