6 HSS titanium step drill bits - Center cone drill bits - Storage box - For progressive and precise drilling

A set of 6 titanium-coated HSS step drill bits, ideal for minimal wear and high durability during repeated drilling. Their graduated design, with diameters ranging from X to Y mm, allows you to drill holes of different sizes without changing tools, ensuring optimal precision. The 135° conical tip ensures self-centering and straight penetration, preventing slippage even in hard materials like stainless steel. The helical flute design reduces vibration and improves chip evacuation, enabling fast and precise cutting. Titanium-coated, these drill bits generate less heat and last up to three times longer than standard HSS drill bits. Suitable for metal, wood, plastic, aluminum, and copper, they offer unlimited versatility on a wide range of materials. Includes a rigid storage case with removable compartments, allowing for organized sorting of drill bits by size and protecting them from impacts during transport. Laser-engraved size markings on each drill bit ensure permanent readability, even after years of use. Designed for both professionals and DIY enthusiasts, these step drill bits are suitable for a wide range of applications: electrical installations, mechanical work, woodworking, and crafting. SMART STEP technology ensures rapid penetration into thin materials (up to 5 mm thick).
