About This

• HSS Titanium Coating: Made of high speed steel with titanium coating, makes the drill bit harder than a typical HSS bit. Enhance durability and perform well in heat, corrosion, and rust resistance.
• 118° Split Point Tip: The step drill bits are designed with 118° split point tip, which can improve the cutting speed while increasing the wear resistance. The two flute design provides a smoother cutting, and allows chips to be removed quickly.
• Automatic Center Punch: With the included spring-loaded automatic center punch, simply place it where you want to drill and it will create a slight indentation to hold the drill bit in place. Use it to mark the hole before drilling to prevent the drill bit from slipping.
• 50 Sizes: 50 sizes of the step drill set ranging from 1/8" to 1-3/8" can meet most engineering or DIY needs. Suitable for various hole diameters, effectively eliminating the hassle of switching between multiple bits. Perfect for drilling holes in plastic, aluminum, copper, iron, etc (Not suitable for hard and brittle materials).
• Storage Solution: The step drill comes with a specially designed storage box featuring a size index. This inclusive design ensures easy organization, prevents debris from falling, and maintains a tidy workspace.
