BIG KAISER Precision Tooling hopes to release products equipped with this technology later in the year.Custom OptionsIn addition to standard finish bor-ing tools, shops can opt for custom fine boring tools like those available from Hollfelder-Ghring GmbH in Nuremberg, Germany. (Guhring Inc. is in Brookfield, Wisconsin.) One of the main differences between custom tools offered by this com-pany and competitive offerings is that Hollfelder-Ghring does not use typical ISO inserts, said Henry Hack, production and technology manager.A typical insert is held in place by a screw.If the insert moves in the pocket seat, the customer loses part preci-sion, Hack said. But if you have a tight fit of your insert in the pocket seat, there is no movement.Hollfelder-Ghringsfinebor-contributorsBIG KAISER Precision Tooling Inc.888-866-5776 www.bigkaiser.comGuhring Inc.800-776-6170 www.guhring.comKennametal Inc.800-446-7738www.kennametal.comctemag.com/cteguide.com35Boring.indd 35 6/18/21 2:47 PM'
