Machine reamer DIN 208, Form B — 26 mm, HSS‑Co (MT3) — TECWERK

The machine reamer DIN 208, Form B, 26 mm is a precision finishing tool designed for H7 holes in steel, non‑ferrous metals and plastics, supplied with a Morse taper MT3 shank for direct machine mounting

• HSS‑Co for enhanced wear resistance
• DIN 208 Form B with H7 tolerance
• Morse taper MT3 shank for secure mounting
• Helical flutes for improved chip evacuation

Precise finishing for consistent hole quality

This reamer delivers a repeatable H7 tolerance, making it suitable where hole accuracy and surface finish are critical. The combination of DIN 208 geometry and a Form B profile ensures that final diameters meet tight specifications while limiting run‑out and taper. For operations requiring predictable assembly fit or accurate bearing seats, the tool provides the dimensional reliability expected in production environments.

Durable cutting performance in mixed materials

Manufactured from HSS‑Co, the tool offers improved hot‑hardness and wear resistance compared with standard high‑speed steels, which extends tool life in continuous use. The alloyed composition is beneficial when machining steel, non‑ferrous metals and plastics, where edge retention and thermal stability reduce the frequency of tool changes and support consistent cycle times.

Efficient chip control and secure machine connection

The reamer’s helical flutes enhance chip evacuation and reduce chatter, contributing to a superior surface finish on through and blind holes. The integrated Morse taper MT3 shank facilitates secure mounting in machines with a matching taper, providing straightforward changeover and stable drive transmission for higher feed rates and longer uninterrupted runs.

Application guidance and production benefits

Drill‑prepared holes finished with this tool achieve the intended tolerance and surface quality without extensive downstream rework. The tool is suitable for finishing both through and blind holes in workshop and light industrial settings, where the combination of robust material and standardised geometry reduces inspection time and supports leaner workflows.

FAQ

What materials can be machined with this reamer?
The TECWERK machine reamer in HSS‑Co is intended for steel, non‑ferrous metals and plastics, as specified for finishing both through and blind holes.

What does H7 tolerance mean for hole quality?
H7 denotes a standardised tolerance class that the reamer is designed to achieve, ensuring consistent nominal diameter and fit suitable for press‑fits or bearing seats when the mating component follows the relevant tolerance class.

How is the tool mounted in a machine?
The tool is supplied with a Morse taper MT3 shank for direct mounting in compatible spindles or adapters, providing a secure connection for reliable machining.

Is this reamer suitable for production runs?
With HSS‑Co construction and helical flutes for improved chip control, the reamer is appropriate for small to medium production batches where consistent hole finish and dimensional repeatability are required.

Which standard does the reamer conform to?
The geometry follows DIN 208, Form B, which defines the reaming profile and contributes to standardised finishing results.
