Cobalt H.S.S. Drill Bits Granded 3.5 x 70mm

Cobalt H.S.S drill bits are high-speed steel drill bits that are made from a blend of cobalt, molybdenum, and tungsten. These materials give the drill bits increased strength and durability, making them ideal for drilling into harder materials such as stainless steel and cast iron. The bits are ground, meaning they have been honed to a precise shape and size, ensuring a smooth, accurate hole every time.

The cobalt H.S.S drill bits come in a range of sizes, from 1.0mm to 16.0mm, making them suitable for a variety of drilling tasks. The small 1.0mm size is perfect for making precise holes in thin materials, while the larger 16.0mm size can handle more heavy-duty jobs. The range of sizes available ensures that you will be able to find the right drill bit for your needs, regardless of the material you are working with.

These drill bits are designed to be used in high-speed drilling applications, as the name suggests. This means that they are capable of cutting through materials quickly and efficiently, making your drilling tasks faster and more convenient. The cobalt material used in these drill bits also gives them excellent heat resistance, ensuring that they will not become damaged or lose their shape when used at high speeds.
