As a solution optimised for good machining results in light to heavy interrupted cuts of case hardened steel, new grade CB7025 broadens the application of Sandvik Coromant cutting tools towards a stronger hard part turning offer.
The key to elevated performance lies in the fine grain CBN, which develops wear in a controlled way and mechanically interlocked insert corners that offer strength and security superior to standard insert edge designs.
These unique properties combine to give a unique and reliable machining experience by allowing high speeds and ability for finishing components in one pass while still retaining surface quality.
Available in a wide range of positive inserts, CB7025 also comes in two patented-radius wiper geometries which allow significant performance improvements -WH geometry for high surface quality with reduced cutting forces and -WG geometry, focussed on providing the best preparation for a finishing cut while running at high feed rates.
Improved performance in toughness demanding operations makes grade CB7025 the first choice for turning case hardened steels, 58-65 HRc.
