Drill America 29 Piece Cobalt Drill Bit Set

The Drill America 29-piece 135-degree split-point heavy-duty drill bit set, manufactured to the National Aerospace standard 907, is designed to deliver exceptional performance. These drill bits exhibit high red hardness, allowing for speeds up to 30% greater than those achievable with conventional M2 High-Speed Steel, making them especially effective in drilling tough, high-tensile-strength materials such as stainless steel, inconel, and titanium.

The 135-degree split point is self-centering and reduces thrust, providing a more efficient drilling process. Cobalt steel tools, similar to high-speed steel but with increased cobalt content, offer improved performance when cutting harder metals like stainless steel or nickel alloys.

Gold oxide, a thinner oxide surface treatment compared to the typically used black oxide, is applied to these cobalt steel tools. This surface treatment provides similar performance to uncoated tools, making them a versatile choice for a wide range of drilling applications.

The round shanks on these drill bits allow for use with a variety of toolholding systems, ensuring compatibility with different equipment and setups. When operated in a counterclockwise direction (right-hand cut), the spiral-fluted design of the tools effectively evacuates chips up and out of the cut, reducing the risk of clogging and improving the overall drilling experience.

Packaged in a durable metal case, the Drill America 29-piece set includes fractional sizes ranging from 1/16" to 1/2" in 1/64" increments, providing a comprehensive solution for a diverse range of drilling needs.

In summary, the Drill America 29-piece 135-degree split-point heavy-duty drill bit set, with its advanced features and performance capabilities, is a reliable choice for professionals and hobbyists alike, tackling a wide variety of materials with efficiency and precision.
