Step Drill Set

A Step Drill Set is a type of drill bit set that is used for drilling holes with different diameters. It consists of multiple drill bits in a single set, each with a different step or increment in diameter. This allows the user to drill holes of various sizes without needing to switch between different drill bits.

Step drill sets are commonly used in applications where multiple hole sizes are required, such as in metalworking, woodworking, or plumbing. They are designed to create clean and precise holes, and they often have a spiral flute design to aid in chip removal and reduce heat buildup.

These sets are typically made from high-speed steel (HSS) or cobalt steel, which are durable and can withstand high temperatures generated during drilling. Some step drill sets may also have a titanium coating or other surface treatment to further enhance their performance and longevity.

Overall, step drill sets are versatile and convenient tools for drilling holes of different sizes, making them a valuable addition to any toolbox or workshop.
