INDEPENDENT HELICAL STEP DRILLS FOR SCREW HOLES

Step drill bits with independent flutes are designed to perform precise holes intended for screw seats in metallic materials. The specific stepped configuration allows the creation of holes with different diameters in a single operation, optimising the process and ensuring an accurate finish. The independent flutes facilitate chip evacuation, improving cutting efficiency and reducing the risk of overheating. These drill bits are suitable for applications requiring precision and reliability in the hole for fastening elements insertion. Their construction is designed to withstand the stresses typical of metalworking, ensuring durability and consistent performance.
