Used in combination with indexable insert I.S.O. ­boring bars, these units can ­produce bores down to 5.5mm ­diameter and up to 34mm diameter. These MICRO heads fit the standard Pinzbohr arbors with ­connection ­diameters (‘SD’) of 27, 32 or 42mm. Graduated precision dial readout to 0.01mm.

Note: If ground inserts used, please specify left hand for boring. Bores as small as 5.5mm diameter can be ­produced by using stepped bars.
