Adjustable reamer 34-38,75 NRZe designed for finishing cylindrical holes in steels, cast irons and non-ferrous alloys provides stable diameter countersink in reaming of H7 holes.
The 34-38.75 mm adjustment range is realized by segmented cutting strips made entirely of high-grade HSS; micrometer radial adjustment with screw locking allows the dimension to be set with allowance for cutting clearance. A 45-degree insertion chamfer stabilizes entry and reduces burrs, a 6-8-degree back relief reduces friction, and the recommended allowance for finishing passes is 0.20-0.35 mm. The NRZe's tempered alloy steel body uses fine-pitch expansion screws for repeatable setting; the multi-blade geometry distributes forces evenly, making it easier to maintain cylindricity and uniform texture in precision reaming.
- Setting accuracy - Adjustment stroke within hundredths of a millimeter enables IT7-IT8 to be achieved without additional transitions.
- Stable operation - symmetrical segment spread and 45-degree chamfer reduce vibration and radial runout, improving dimensional repeatability.
- Flexible range - the 34-38.75 reamer covers several diameters in one set, reducing changeovers and calibration time.
- HSS durability - resistance to tempering promotes longer sharpening intervals with proper cooling.
Dimensional conformity referenced to ISO 286-2 (H7), and shape and position requirements are defined by EN ISO 1101; control of radial runout of strips recommended ≤ 0.02 mm in the working section.
The 34-38.75 NRZe adjustable reamer provides predictable doming, stable cylindricity and wear compensation capability over the full 34-38.75 mm adjustment range.
