Drill America DWDCO Series 3/8 Cobalt Drill Bit Pack of 6

Manufactured to National Aerospace standard 907, these drill bits are designed to deliver exceptional performance. Featuring a heat-resistant cobalt composition, they exhibit higher red hardness, enabling speeds up to 30 percent greater than High-Speed Steel drills. This makes them particularly effective in drilling tough, high tensile strength materials such as PH stainless steel, inconel, and titanium.

Cobalt steel tools are similar to high-speed steel, but with a higher cobalt content for improved performance when cutting harder metals, including stainless steel and nickel alloys. The gold oxide surface treatment is a thinner oxide layer compared to the typical black oxide, and it serves to identify the cobalt steel composition. The performance of these coated tools is on par with their uncoated counterparts.

The round shanks on these drill bits allow for use with a wide variety of toolholding systems, offering versatility and flexibility in various applications. When run in a counterclockwise direction (right-hand cut), the spiral fluted design effectively evacuates chips up and out of the cut, reducing the risk of clogging.

This drill America jobber length drill bit, manufactured to the rigorous National Aerospace standard 907, is a testament to the quality and precision engineering required for mission-critical aerospace and industrial applications. Its advanced features and materials make it a reliable and efficient choice for drilling into tough, high-strength materials, ensuring optimal performance and productivity.
