The 13-piece cobalt drill bit set includes drill bits in the following sizes: 1/16, 5/64, 3/32, 7/64, 1/8, 9/64, 5/32, 11/64, 3/16, 13/64, 7/32, 15/64, and 1/4 inch. These bits are suitable for use with most electric drills currently on the market.

[High Quality Material] These industry-grade M35 drill bits contain 5% cobalt and have undergone complete grinding to achieve precise drilling diameters. This process enhances the wear resistance and durability of the bits, making them significantly harder than high-speed steel drill bits from similar sets.

[135° Split Point] The 135-degree quick-cut split point and straight shank design of these drill bits is self-centering, allowing them to penetrate metal quickly with less pressure and preventing bit walking. This feature enables faster drilling performance without the need for a center punch.

[Multiple Applications] These versatile drill bits are ideal for cutting through a variety of materials, including hard metals such as stainless steel, steel, sheet metal, and cast iron, as well as plastics, aluminum alloys, wood, and other softer metals. Users should exercise caution with speed, pressure, and heat control when drilling.

[Professional After-Sales Service] The drill bits come housed in a metal storage case for easy organization and protection. If you are not completely satisfied with the product for any reason, please contact the manufacturer, and they will provide a sincere and helpful response.
