Goebel Fasteners, Inc. high speed steel (HSS) cobalt drill bits are made from premium cobalt steel to provide superior hardness and are very resistant to abrasion. Goebel premium high speed steel (HSS) cobalt drills give you longer tool life than ordinary cobalt drills reducing the cost per hole drilled. These cobalt drill bits are designed for the drilling of tough and abrasive materials, high temperature alloys and stainless and heat treated high strength steels. With an extended tool life, Goebel cobalt drill bits will give you the lowest cost per hole drilled.

Goebel premium high speed steel (HSS) cobalt drill bit design gives you the best point for optimum penetration and flute geometry assuring constant chip ejection. The short flute and length keep these bits straight for accurate placement when starting holes that will be drilled deeper with a longer bit; also known as spotting drill bits. High speed steel (HSS) cobalt steel bits are heat resistant and maintain their sharp edges when drilling hard material. They are for use in both hand-held drilling and machine-tool applications.

High speed steel (HSS) cobalt steel bits have better heat and wear resistance, so they can run up to 25% faster and have a longer tool life. Goebel premium cobalt drill bits are particularly successful in cutting through hard metals such as stainless steel and cast iron, although they can be used for softer materials, too.

A number of factors determine which drill bit will be best for an application, including the type of material to be drilled, drilling speed, and desired number of holes per bit. Select a drill bit with the combination of material, finish, length, and style that will be best-suited for your job. Cobalt drill bits are often more expensive than other standard drill bits, but if you regularly drill through metal, they are a good investment since they tend to last longer.
