Adjustablereamer 37,5-45 mm NRZe for finishing cylindrical holes in steel, cast iron and non-ferrous alloys provides precise diameter and geometry control, designed for reaming H7 holes.
The 37.5-45 mm adjustment range is realized by segmented cutting strips made entirely of high-grade HSS; micrometric radial adjustment with screw locking allows setting the dimension with allowance for cutting clearance. A 45-degree insertion chamfer stabilizes entry and reduces burrs, a 6-8-degree back relief reduces friction, and a recommended allowance of 0.20-0.35 mm promotes a uniform surface texture. The NRZe's tempered alloy steel body and fine-pitch expansion screws ensure repeatable setting, and symmetrical segment spreading promotes uniform loading and wear compensation over the series.
- Dimensional stability - uniform force distribution and multi-tool geometry improve cylindricity and diameter repeatability.
- Quick calibration - micrometer set screw allows corrections within hundredths of a millimeter without additional passes.
- Wide range - the 37.5-45 reamer covers several diameters in a single setting, reducing changeovers and calibration time.
- Surface quality - 45-degree chamfer and controlled relief support reaming of H7 holes with predictable roughness.
Dimensional conformance referenced to ISO 286-2 (H7/H8), and shape and position tolerances are defined by EN ISO 1101; proper selection of allowance and coolant determines diameter stability in the finishing pass.
The 37.5-45 mm NRZe adjustable reamer ensures that the dimension is maintained within the tolerance field, stable cylindricity and the ability to compensate for wear over the full 37.5-45 mm range.
