Cobalt Drill Bits

Cobalt Drill Bits

Cobalt drills from Atlas Cutting Tools are made from a high-speed steel alloy that contains cobalt, which makes them very tough and resistant to heat. This makes them ideal for drilling through tough and hard materials such as stainless steel, titanium, and cast iron, where the high heat generated during drilling can cause carbide drills to wear down quickly. Cobalt jobber drills are also more affordable than carbide drills, making them a good option for general-purpose drilling applications where high precision and speed are not required.
 

Cobalt jobbers and aircraft extension drills share many features, including:

  • High-speed drilling: Cobalt jobbers and aircraft extension drills are designed to drill at high speeds, which makes them ideal for use in manufacturing and production settings where speed and efficiency are important.

  • Heat resistance: Cobalt jobbers and aircraft extension drills are designed to withstand high temperatures generated during drilling, which helps to prevent the drill from overheating and wearing down prematurely.

  • Hardness and durability: Cobalt jobbers and aircraft extension drills are made from a hard and durable material that is resistant to wear and tear, making them ideal for heavy-duty drilling applications.

  • Versatile: Cobalt jobbers and aircraft extension drills can be used to drill through a wide range of materials, including metals, plastics, and composites. This makes them a versatile tool for a variety of drilling applications.

Cobalt jobbers and aircraft extension drills are commonly used in a wide range of applications, including:

  • Metalworking: Cobalt jobbers and aircraft extension drills are ideal for drilling through tough materials such as stainless steel, cast iron, and titanium. They are commonly used in metalworking applications such as machining, drilling, and tapping.

  • Aerospace and aviation: Aircraft extension drills are commonly used in the aerospace and aviation industries to drill through tough materials such as titanium and other aerospace alloys. Their long length and flexibility make them ideal for drilling in hard-to-reach areas.

  • Plumbing and HVAC: Cobalt jobbers and aircraft extension drills are commonly used in plumbing and HVAC applications to drill through pipes, ductwork, and other materials.

  • Woodworking: Cobalt jobbers and aircraft extension drills can be used to drill through wood, MDF, and other wood-based materials. They are commonly used in woodworking applications such as cabinetry, furniture making, and carpentry.
