Drill America DWDCO54P12 #54 Cobalt Drill Bits (12-Pack), DWDCO Series

The Drill America DWDCO series Qualtech economy cobalt steel reduced shank drill bit is made of heat-resistant cobalt steel and ground to a heavy-duty 135-degree split point. The drill bit features a common flute and overall length for minimal adjustment during tool changes. It is precision-ground for a high degree of concentricity between the shank and body diameter, making it ideal for drilling in tough, high-tensile-strength materials.

Cobalt steel tools are similar to high-speed steel, but they contain more cobalt, which improves their performance when cutting harder metals such as stainless steel or nickel alloys. The gold oxide surface treatment used on these tools is thinner than the typical black oxide, making it easier to identify the cobalt steel.

The round shanks of these drill bits allow them to be used with a wide variety of toolholding systems. When run in a counterclockwise direction (right-hand cut), the spiral fluted tools evacuate chips up and out of the cut, reducing the risk of clogging.

These drill bits are designed to be ideal for drilling in tough, high-tensile-strength materials, making them a versatile choice for a variety of applications. The precision grinding and cobalt steel composition ensure a high level of performance and durability, even when working with challenging workpiece materials.

Overall, the Drill America DWDCO series Qualtech economy cobalt steel reduced shank drill bits offer a combination of features that make them well-suited for a range of drilling tasks, particularly in demanding high-strength materials. The use of cobalt steel and the thoughtful design of the flutes and shanks contribute to their effectiveness and efficiency in the workshop or production environment.
