The Ultra Touch HSS Step Drill Bit Set (4–12mm, 4–20mm, 4–32mm) is a professional-grade 3-piece drilling solution designed for creating multiple hole sizes using a single tool. This set eliminates the need for frequent bit changes, improving efficiency and productivity.

Crafted from High-Speed Steel (HSS), the drill bits offer excellent durability, heat resistance, and long service life, making them ideal for demanding applications. Each bit features a Titanium Nitride coating, which reduces friction, minimizes heat buildup, and enhances cutting performance for smoother drilling.

The set includes three step drill bits covering a wide range (4mm to 32mm), enabling users to drill multiple hole sizes with precision and ease. The double-flute design ensures efficient chip removal and clean, burr-free holes, while the hex/triangular shank provides a secure grip to prevent slipping during operation.
