Drill America D Cobalt Drill Bit (Pack of 12), DWDCO Series

The Cobalt Drill Bits: Engineered for Exceptional Performance

Manufactured to the National Aerospace Standard 907, these cobalt drill bits are designed to offer exceptional performance in a wide range of applications. Crafted from heat-resistant cobalt, they display a higher red hardness, enabling them to operate at speeds up to 30% greater than high-speed steel drills.

These cobalt steel tools are similar in composition to high-speed steel, but with an increased cobalt content for improved performance when cutting harder metals, such as stainless steel or nickel alloys. The cobalt-rich formulation makes them especially effective in drilling tough, high-tensile-strength materials, including PH stainless steel, Inconel, and titanium.

The drill bit's surface treatment is a thinner oxide coating, known as gold oxide, which helps to differentiate cobalt steel tools from their uncoated counterparts. The performance of these coated tools is comparable to that of uncoated tools, providing a practical and cost-effective solution.

The drill bits feature round shanks, allowing for versatile use with a wide variety of toolholding systems. This design flexibility ensures compatibility with various machinery and equipment, making them a valuable asset in diverse manufacturing environments.

When operated in a counterclockwise direction (right-hand cut), the spiral-fluted design of these drill bits efficiently evacuates chips up and out of the cut. This feature helps to reduce clogging, enhancing the tool's performance and longevity.

Manufactured to the stringent National Aerospace Standard 907, these cobalt drill bits are engineered to deliver exceptional results. Their combination of superior material composition, specialized surface treatment, and innovative design features make them a reliable choice for tackling challenging drilling tasks in a wide range of industries.
