spiral drill bit
A groove spiral step drill bit, also known as a step drill bit, is a type of drilling tool used to create holes of varying diameters in materials like metal, wood, and plastic. The bit features a conical shape with multiple steps that gradually increase in diameter from the tip to the base.The spiral grooves on the bit help to evacuate chips and debris from the hole, while the step design allows for more efficient drilling with less pressure and torque required. These bits are commonly used in metalworking and plumbing applications, and can be found in both high-speed steel and carbide materials.
