Special Features
Premium Quality Material: Drill bits are made of high speed steel (HSS), making them harder and more durable than typical HSS bits. High speed steel bits are coated in black for maximum durability and sharpness. They reduce friction, run cooler, and perform well in extreme temperatures, making them resistant to corrosion and rust.
Size: Our 3 multiple hole stepped up bits come in 24 different sizes, making it convenient to drill different hole sizes with just one step drill. 4-20 (4mm, 6mm, 8mm, 10mm, 12mm, 14mm, 16mm, 18mm, 20mm), 3-12 (3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, 12mm), 4-12 (4mm, 6mm, 8mm, 10mm, 12mm). Perfect for DIY projects at home, garden, workshop, and more.
Faster and Smoother Cutting: With a two-flute design, drill bits cut through materials faster and smoother than other bits on the market. Step drill bits have a small point angle of 118°, which requires less pressure when centering in the material. The point starts drilling at contact, reducing friction, pressure, and heat. This means you can drill through materials with ease.
Easy to Carry: Set includes 3 pieces of step drill bits, each with a different size range, all neatly organized in an storage box for easy storage and transport. Meticulously manufactured drills come with high-visibility digital laser measurements, making it easy to find the size you need and improve drilling accuracy.
Versatile: Used for DIY and sheet metal work, processing thin steel, aluminum, wood, resin, etc. Can be used for various purposes such as drilling, enlarging drilled holes, chamfer and burr. The hexagonal shank makes it suitable for mounting on the drill heads of impact drivers, electric drills and cordless drills. Recommended drilling speed: 300-500 rpm, it is an indispensable tool for improving work efficiency.
