BORLETTI micrometer set 0-200 mm

Painted frame with hard metal contacts. Easy reading thanks to careful character execution, incision depth. Particularly accurate spindle screw-rod machining, obtained in an environment kept at 20°C. Screw fully hardened and stabilized; after roughing the thread, it is subjected to a special ageing treatment before finishing, to avoid variations due to residual internal stresses. Contact surfaces are extremely finely finished to Ra 0,025 µm.

Clamping device easily accessible. Thermal insulation plates applied to the frame. Steel lamina friction that, by size and position on the drum, meets the dual requirement of accessibility both on the support (see item SUM) and in the more frequent use with the workpiece and tool held in hand. They feature a vernier reading system that makes them extremely easy to use, even for non-expert personnel. Frame with thermal insulation. Hard metal contacts.
