The extra-long finishing machine reamers, with diameters ranging from 2 mm to 20 mm and H7 tolerance, manufactured according to DIN 212 standards, are precision tools ideal for mechanical processing. These reamers, featuring a cylindrical shank with h8 tolerance, are made of HSS-E steel and equipped with left-hand helix cutting edges at 42°.

Designed and produced by UTENSILERIA OSSOLANA, these tools are optimal for achieving precise holes in a wide range of materials, including those used in automatic machines, such as leaded or sulfurized steels and light alloys.

The extra-long reamers can also be used for working on more challenging materials and in small production batches, ensuring excellent results and consistent, reliable quality even in limited production runs.

The cylindrical shank with h8 tolerance ensures a secure and stable grip in machine tools, reducing vibrations and increasing precision. This is particularly useful in applications where perfect concentricity and high power transmission are required.

Using HSS-E reamers with these features allows for tight tolerances, especially with an H7 tolerance class, ideal for applications where hole diameter accuracy is crucial. The combination of HSS-E steel's robustness and the precision of the cylindrical shank makes these reamers an excellent choice for producing high-quality mechanical components.
