Step Drill Bit Set | 5-Piece Titanium-Coated HSS | Multi-Size Metal Drilling Kit

Engineered for precision and speed, this 5-piece step drill bit set features four-spiral flute titanium-coated HSS steel for clean, burr-free holes in sheet metal up to 4mm thick. The 50 integrated step sizes from 4mm to 32mm eliminate bit changes, delivering professional results with reduced chatter and extended tool life. Features and Benefits - Titanium-Coated HSS Steel - Provides superior hardness and heat resistance for drilling through hardened steel, stainless steel, and aluminum with less friction and wear. - Four Spiral Flutes - Efficiently evacuates metal chips to prevent clogging, ensuring smoother operation, faster drilling speeds, and a cleaner finished hole. - 50 Integrated Step Sizes (4-32mm) - One bit creates multiple hole diameters, saving time and increasing workshop efficiency by eliminating the need for multiple standard drill bits. - 1/4 Inch Hex Shank - Ensures a secure, slip-free grip in all standard cordless drills, impact drivers, and drill presses for maximum power transfer and safety. - Precision Ground Tips - Start holes accurately with minimal walking or skidding on curved or flat metal surfaces, reducing material waste and rework. Applications - HVAC and Electrical Work - Quickly create clean, precise holes for conduit, piping, and wiring in electrical panels, junction boxes, and ductwork. - Automotive Fabrication and Repair - Ideal for enlarging existing holes or creating new ones in body panels, brackets, and exhaust components without deburring. - General Metalworking and DIY Projects - Perfect for installing locks, crafting brackets, or modifying metal furniture and appliances in home workshops.
