HSS Step Drill Bit - TiN Coated, Triangular Shank

This high-speed steel (HSS) step drill bit with titanium nitride (TiN) coating delivers professional-grade performance for drilling and enlarging holes in a wide range of materials. The advanced coating provides superior hardness, heat resistance, and wear durability, ensuring the bit stays sharp and effective through extended use.

The unique triangular anti-slip shank is engineered for secure, slip-free clamping in standard 3-jaw drill chucks - eliminating bit spinning and ensuring consistent drilling accuracy. It is universally compatible with electric hand drills, cordless power drills, and bench drill presses.

The progressive stepped cone design allows you to drill and enlarge holes in a single operation, eliminating the need to swap multiple individual drill bits. Each step produces clean, burr-free holes, while the straight flute geometry ensures efficient chip removal for smoother drilling.

Clear, permanent laser-engraved diameter markings on each step allow for instant size identification and accurate depth control - reducing measurement errors and saving you time on every job.

This versatile bit is suitable for drilling sheet metal, aluminum alloy, wood, PVC, plastic, thin iron plates, and other soft to medium materials. It is ideal for electrical installation, sheet metal fabrication, auto repair, furniture assembly, and DIY projects. One tool replaces many - a cost-effective addition to any workshop or toolbox.
