TungDrillTwisted – Bracket – AH7020
IMPROVED TOOL LIFE AND HOLE DIAMATER ACCURACY
Thanks to the superior wear resistance of the new grade AH7020, tool life has improved by 1.2 times compared to the conventional grade.
Additionally, while the conventional grade occasionally exceeded hole diameter tolerances, the AH7020, which has achieved higher precision through advancements in manufacturing technology, is now capable of meeting the required precision.
