Straight-form wheel · Central bore · Drawing-based quotation
Product Overview
These unmounted vitrified-bond CBN wheels use a central bore for installation on a compatible arbor or holder. They are intended for precision internal features in hardened ferrous components, including bores, raceways, grooves and application-specific profiles. The wheel geometry, abrasive specification and operating limits must be confirmed from the final application data and approved drawing.
