What are carbide drill bits made of?

Also known as screw-machine and stub-length bits, these provide maximum rigidity for drilling straighter holes than jobbers’-length drill bits. Made of solid carbide for the highest accuracy and longest tool life, they are harder, stronger, and more wear resistant than high-speed steel, cobalt steel, and carbide-tipped bits. They retain a sharp, hard edge at high temperatures for the best performance on hard and abrasive material. These bits require rigid toolholding to prevent breakage and should not be used in hand-held drilling applications. They have either a four-facet or split point to keep the bit centered without a pilot hole.

What are jobber bits made of?

These jobbers’ -length bits have the rigidity and length required for most applications. Made of solid carbide for the highest accuracy and longest tool life, they are harder, stronger, and more wear resistant than high-speed steel, cobalt steel, and carbide-tipped bits. They retain a sharp, hard edge at high temperatures for the best performance on hard and abrasive material. The four-facet point keeps the bit centered without a pilot hole. These bits require rigid toolholding to prevent breakage and should not be used in hand-held drilling applications.

What is a screw machine bit?

Also known as screw-machine and stub-length bits, these provide maximum rigidity for drilling straighter holes than jobbers’ -length drill bits. Made of cobalt steel, which has better heat and wear resistance than high-speed steel, they can run up to 25% faster and have a longer tool life.
