Material:
-The drill bits are made from M35 high-speed steel, which contains 5% cobalt, resulting in higher hardness, making them highly effective for machining high-hardness materials and metals., making it suitable for drilling various hard metals, including stainless steel, iron, copper, aluminum alloys, and cast iron.

Surface Treatment：
-Nitriding Black, while its surface treatment provides enhanced oxidation and corrosion protection, extending drill bits' service life and making them suitable for drilling hard metals and other materials.

TIP:
-When using a large drill bit, it's best to start by drilling smaller holes. This makes it easier to create larger holes accurately.
-When ues reduced shank drill bit, it's important to maintain a 90-degree vertical angle to ensure precision and accuracy.
-For power drills, it's recommended to use a model with a power rating of 750W or higher.
-Use water or coolant to lower the temperature and prevent the drill bit from overheating, especially when drilling hard metal like stainless steel materials.
