As an example, he pointed to Iscars The Gold standard for Finefit product, which is adjustable steel turning applications both radially and axially.Another adjustable offering from Iscar is its Bayo T-Ream high-speed reaming system. He explained that Bayo T-Ream features three adjust-ment screws that can be tightened Reamers offer much higher penetration rates than single-point boring bars.Tigertec Gold can handle almost any challenge involved insteel turning.
