The DWTET Series extension tap is specifically designed for tapping the hubs of pulleys, making it ideal for applications involving oil caps or set screws. Its extended shank allows access to holes that standard-length taps cannot reach, enhancing versatility. Crafted from high-speed steel, these tools excel in general-purpose tasks, providing an excellent balance of hardness and toughness for superior wear resistance. The uncoated tools consist solely of the base substrate, making them suitable for a variety of applications. They feature a round shape with a square end shank. Additionally, the right-hand cut design ensures effective cutting action when operated in a clockwise direction.
