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.
  • 【Precision-Engineered Design】The Automatic Center Punch swiftly and precisely creates positioning indentations on surfaces, ensuring accurate drilling without misalignment. 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.
  • 【Convenient Storage Solution】This step bit set includes a specially designed holder with a size index, ensuring each bit is securely stored. 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.
  • 【Wide Range of Applications】Ideal for drilling holes in plastic, aluminum, wood, iron, and various other types of sheet metal (it is recommended to add coolant when drilling metal plates, and the speed should not be too high). Suitable for home DIY, handymen, and professionals.

Aoocoom Titanium-Coated Step Drill Bit Set for Metal, High-Speed Steel Stepped Drill Set, 50 Sizes with Automatic Center Punch, Includes Aluminum CaseWhen I need a step drill it is usually into plastic or mild steel. However, I ruined 2 step drills from another set trying to drill into what was apparently some hardened steel. These will be the replacement bits. They look to be about the same quality as my old bits so I will say these are average. They do come in a decent aluminum carry case which is nice to keep them protected. Automatic center punch worked very well on some mild steel that I tested it with.

How does a product not have a box? Also, it seems like the product arrived used. Not at all pleased.

This Titanium-Coated Step Drill Bit Set is well-made and of great quality, crafted from high-speed steel. The titanium coating enhances durability, making it ideal for drilling through various metals like steel, aluminum alloy, and copper. It can also drill through wood, though it's best to choose the appropriate bit size for that.This set is perfect for DIY enthusiasts like me, allowing the creation of small projects like metal models and wooden furniture. With five standard step drill bits covering 50 different sizes, it eliminates the hassle of switching between multiple bits and meets most drilling needs.The titanium coating increases hardness and reduces wear, enhancing both durability and drilling efficiency. I also appreciate the automatic center punch, which makes precise positioning easy and prevents hole misalignment.The aluminum case is a thoughtful addition, keeping the bits organized, well-protected, and easy to carry. I used this set to install handles on a storm door, and it drilled through medium-thickness aluminum alloy quickly, efficiently, and with smooth, neat holes.

I got this for some light metal work and they've been fine so far. Just what it says on the tin. Quality is decent and it comes in a case which is nice. So far it's been fine, so no complaints yet. It has a good assortment of sizes

I always like to have drill bits on hand for all kinds of jobs, you never know when you might just need them. I had to attach some shelves to my rolling toolbox and these bits made quick work of this task.

Tried to enlarge a hole with the large bit and it wouldn't cut through the first step. I couldn't recommend these bits.
