Made of heat resistant cobalt and ground to a heavy duty 135° split point. Common flute and overall length for minimal adjustment during tool changes. Precision ground for high degree of concentricity between shank and body diameter. Ideal for drilling in tough, high tensile strength materials. Expands the size range capacity of a portable drill chuck. Common flute and overall length for minimal adjustment during tool changes. Precision ground for high degree of concentricity between shank and body diameter. Ideal for drilling in low and medium tensile strength materials.
Black and gold oxide finish,for smoother drilling and is more durable and corrosion resistant.135-degree penetrates hard material and produces small chips to reduce clogging.The split point tip can increase the wear resistance,increases cutting speed with self-centering,clears chips and particles faster.
Reduced Shank:Reduced Shank Drills expand the size range capacity of a portable drill chuck. Common flute and overall length for minimal adjustment during tool changes.
Advantages
Cobalt steel tools are similar to high-speed steel, but with more cobalt for improved performance when cutting harder metals such as stainless steel or nickel alloys.
Gold oxide is a thinner oxide surface treatment than black oxide typically used to identify cobalt steel tools; performance is similar to uncoated tools.
Round shanks allow use with a wide variety of tool holding systems.
When run in a counterclockwise direction (right-hand cut) spiral fluted tools evacuate chips up and out of the cut to reduce clogging.
For 14 years, Jiacheng Tools has been committed to providing high-performance tools that exceed customer expectations. Through our unremitting efforts, we have established great reputation in the industry and gained the trust of our clients.
