KEENTECH Carbide-Tipped Annular Cutter, 5/8" Diameter x 1-3/8" Depth, 3/4" Weldon Shank (2 Flat), High Speed Cutting TCT Mag Drill Bit with Pilot Pin for Harder Material, Stainless Steel, Cast Iron

Features

• 【Specifications】 - KEENTECH Annular Cutter features a premium carbide cutting edge for outstanding durability, making it ideal for drilling harder materials like stainless steel. It offers a 5/8" cutting diameter and a 1-3/8" cutting depth, and comes with a free pilot pin. The 3/4" weldon shank design is compatible with various magnetic drills, including but not limited to Alfra, Evolution, Dewalt, and Hougen.
• 【Higher Speed Cutting】 - The KEENTECH TCT Annular Cutter features a carbide-tipped head that is harder and sharper. Compared to high-speed steel (HSS) cutters, our TCT cutter offers cutting speeds that are 3-5 times faster. With a three-edge cutting design, each edge shares one-third of the workload, improving cutting efficiency, precision, and finish. For harder metal materials such as carbon steel, stainless steel, cast iron, cast copper, alloy steel, and high manganese steel, our annular drills bits deliver superior cutting performance.
• 【Better Heat Resistance】- KEENTECH mag drills bits feature carbide tips, providing superior heat resistance and higher hardness, suitable for high-temperature machining environments. The heat resistance maintains the cutting edge's hardness and sharpness, enabling high-speed feed and metal cutting within a short period, thus improving efficiency. Additionally, it reduces tool wear or deformation due to overheating, resulting in cost savings.
• 【Clean & Crisp Cutting】 - TCT magnetic drills bits with sharper cutting edges, requires less cutting force when cutting hard materials, resulting in a smoother cutting process. Less friction and roughness, it delivers cleaner and more precise cut finish for high-precision machining scenarios. Plus, they generate less heat, reducing the risk of material deformation or burnishing.
• 【Usage Instructions】 - First, ensure that the two flats of the Weldon shank are aligned with the screws during installation for stable cutting. Second, use the recommended cutting fluid (over 1000 cuts), rather than water(only for 3-5 cuts), choosing the right cutting fluid is crucial for extending the tool's life. Third, the right RPM and feed rate can help you double your efficiency.
