NSBH-ATH is the latest drill bit for hardening materials. It is designed to contain a special sharp tip with internal oil hole, which is important for releasing or pushing scraps from the bottom of the hole into the rake angle by using the pressure of coolant until the scraps are finally released without the need of drill lift, providing the drilling to be in higher condition with no need to worry about tremble or heat accumulation in scraps inside the hole while drilling. Also, Coating ATH is the exclusive copyright of MOLDINO, which can prevent the cutting angle effectively. Its special characteristics are heat resistant, oxidation reduction, and prolong the lifetime of tool.
Therefore, NSBH-ATH is a high effective tool and perfectly suitable for drilling work pieces or materials with the hardness value of up to 60HRC that is difficult for machine.
