• Specifications : MDBTTOOLS Annular Tool features premium carbide cutting edges for excellent durability, ideal for drilling harder materials like stainless steel. Universal Shank Compatible with 3/4" Weldon Shark and Other Standard Tool Holder
• Higher Cutting Speed: TCT Annular Tool features a harder, sharper carbide tip. Compared to High Speed Steel (HSS) tools, our TCT tools cut 3-5 times faster. With a three-edge cutting design, each edge shares one-third of the workload, improving cutting efficiency, accuracy, and finish. For harder metal materials like carbon steel, stainless steel, cast iron, cast copper, alloy steel, and high manganese steel, our Annular Drill Bits offer superior cutting performance
• Better Heat Resistance: MDBTTOOLS The magnetic drill bit uses a carbide tip, which has excellent heat resistance and higher hardness, and is suitable for high-temperature processing environments. Heat resistance maintains the hardness and sharpness of the cutting edge, enabling high-speed feed and metal cutting in a short time, thereby improving efficiency. In addition, it can also reduce tool wear or deformation due to overheating, thereby saving costs.
• Clean and sharp cutting: TCT magnetic drill bits have sharper cutting edges and require less cutting force when cutting hard materials, making the cutting process smoother. Less friction and roughness, providing cleaner and more precise cutting results for high-precision processing scenarios. In addition, they generate less heat, reducing the risk of material deformation or grinding.
• Instructions for use: Make sure the flat surface of the handle is aligned with the screw when installing to achieve stable cutting. Second, use the recommended cutting fluid (over 1000 cuts) instead of water (only for 3-5 cuts). Choosing the right cutting fluid is essential to extend tool life. Third, the correct rotation speed and feed rate can help you double your efficiency.
