The M35 cobalt step drill bit set is an essential tool for anyone looking to achieve precision in their drilling tasks. This set includes three high-quality drill bits, ranging from 1/8ft to 7/8ft, designed specifically for various materials including metal, carbon steel, stainless steel, wood, and plastic.
One of the standout features of this set is the four flute step drill bit design. Unlike ordinary step drills that often suffer from deflection during cutting, our four flute design provides enhanced stability. This means you can enjoy improved accuracy and cutting speed, making it ideal for stainless steel drilling. Additionally, these bits offer several times the service life compared to standard step drills.
Constructed from M35 cobalt HSS, these drill bits are engineered for hard materials. With a high hardness rating of HRC 64-66, they exhibit excellent red hardness and wear resistance, making them perfect for the toughest jobs. The proper heat treatment applied to these bits ensures higher toughness and bending strength than typical high-speed steel options.
Another impressive feature is the TiAlN coating on each bit. This cutting-edge material is not only extremely hard but also capable of withstanding high oxidation temperatures. The exceptional thermal hardness, strong adhesion, and low friction coefficient of the TiAlN coating make these drill bits an ideal choice for demanding applications.
The design of the drill bits includes a larger cutting angle of 135 degrees. This angle is crucial when drilling hard materials as it reduces self-wear and provides a larger stress area. As a result, users can expect cleaner and more efficient drilling, which is essential for achieving professional results.
To ensure the longevity of your drill bits, we recommend following a few simple tips. Using cutting oil or spraying water during continuous use can help keep the drill cool. Additionally, be aware that the start-up speed may be slower due to the larger cutting angle, but this is a small trade-off for the enhanced performance.
We stand behind our products and offer a 100-day warranty for your peace of mind. If you encounter any quality issues, please feel free to contact us. The M35 cobalt step drill bit set is a reliable choice for both professionals and DIY enthusiasts, ensuring you have the right tools for any drilling task.
