About this product

This 2 Inch HSS Step Drill with Spiral Flute and TiN Coating is engineered for efficient and precise hole creation across a variety of materials. Its primary function is to create clean, burr-free holes of varying diameters with a single tool, eliminating the need for multiple drill bits and reaming operations. The spiral flute design enhances chip evacuation, leading to smoother cutting and reduced heat buildup, while the Titanium Nitride (TiN) coating significantly increases hardness, wear resistance, and tool life, allowing for higher cutting speeds and improved performance. Constructed from High-Speed Steel (HSS), this drill bit offers exceptional durability and strength, suitable for demanding industrial applications. The tapered cutting edges are a key feature, enabling simultaneous deburring or chamfering of the finished bore, saving valuable time and labor. While specific size variants are not detailed, the 2-inch diameter is a standard offering for versatile hole sizes. This step drill is ideal for applications in metal fabrication, electrical installation, plumbing, and automotive repair, where precise hole sizing and finishing are critical. Target buyers include importers, wholesalers, and industrial end-users seeking high-performance cutting tools. Its robust construction and advanced coating make it a reliable choice for international trade, offering consistent quality and extended operational life for diverse global markets.
