TECWERK Machine Reamer DIN 208 H7 — 30 mm, HSS‑Co, Morse Taper 3

The TECWERK Machine Reamer DIN 208 H7 is a precision finishing tool for blind and through holes in steel, non‑ferrous metals and plastics.

• HSS‑Co construction for improved wear resistance
• DIN 208 H7 tolerance for precision finishes
• Left‑hand helix with helical flutes for smooth cutting
• Morse taper 3 shank for secure machine mounting

Reduce rework with consistently tight tolerances

The tool delivers repeatable hole dimensions thanks to the H7 tolerance specified in DIN 208. This level of control reduces the need for secondary operations and minimises scrap by producing holes that meet fit and clearance requirements on the first pass. The combination of cobalt‑alloyed high‑speed steel (HSS‑Co) and the specified tolerance supports predictable outcomes in batch production, which in turn improves process efficiency and throughput.

Longer tool life through robust geometry and material

Constructed from HSS‑Co, this reamer resists wear under continuous operation. The helical flutes and left‑hand helix geometry promote reliable chip formation and evacuation, preventing clogging in blind holes and enhancing surface finish. These design choices translate into a longer service interval and steadier dimensional stability, meaning fewer tool changes and less downtime on the shop floor.

Versatile across common workshop materials

Designed for both blind and through holes, the cutter is suitable for steel, non‑ferrous metals and plastics, providing flexibility for mixed production runs. The right‑cutting design combined with the helical flute pattern ensures that cutting forces remain controlled across these materials, producing a clean bore without excessive material pulling or tensile damage to softer substrates.

Easy integration into machine setups

The Morse taper 3 shank simplifies mounting and ensures axial alignment in machines equipped for MT3 tools. This secure fitting reduces runout and helps preserve the precision of the finished hole. Where process validation is required, the DIN 208 specification and the robust shank interface make the tool straightforward to document and repeat within machine programmes and quality records.
