Titanium has excellent characteristics such as being lightweight and strong, but it is also a metal that is difficult to drill. The reasons for this include its high tensile strength, which causes tools to wear easily, and its low thermal conductivity, which leads to heat buildup between the tool and the material. Additionally, while titanium materials and products do not ignite, titanium shavings can react with oxygen or nitrogen in the air and pose a fire hazard. Therefore, it is important to exercise extreme caution in the working environment and when handling shavings. To achieve high-quality drilling of titanium, it is essential to slow down the drill's rotation speed and use cutting oil.
