About this item

• 【HSS Titanium Coating】Crafted from high-speed steel (HSS) and enhanced with a titanium coating, our drill bits deliver outstanding durability and retain sharpness, even under challenging conditions. The titanium layer boosts wear resistance, reduces friction, and ensures cooler operation.
• 【Versatile Hole Processing】Our set of five standard step drill bits covers a wide range of hole diameters, effectively replacing 50 individual bits. This design eliminates the hassle of switching between multiple bits, allowing you to drill various hole sizes to meet all your DIY needs.

The 118° split point tip enhances cutting speed and wear resistance, while the two-flute design ensures smoother cutting and efficient chip removal, making your drilling tasks easier and more precise.

The cone bits are neatly arranged in a case, making transport and storage easy while preventing them from falling out, keeping your workspace organized and clutter-free.
