HSS Titanium Coated Step Drill Bit Set 4-12mm 4-20mm 4-32mm Elevate drilling performance with three sizes in one durable titanium-coated HSS kit. It reduces friction and heat for cleaner holes through steel, brass, wood, and plastic, with faster cutting and portable storage in a cloth bag for on‑the‑go tasks.

• Q: What is the HSS Titanium Coated Step Drill Bit Set 4-12mm 4-20mm 4-32mm best for in DIY and professional drilling?
  A: This HSS Titanium Coated Step Drill Bit Set is ideal for quickly creating clean, graduated holes across metal, wood, and plastic. The titanium coating reduces heat and friction, extending life even under high-speed drilling. With 4-12mm, 4-20mm, and 4-32mm steps, you can switch between hole sizes without changing bits, saving time on metalworking, cabinetry, and electrical installations.
• Q: What sizes are included and how do they cover 4-12mm, 4-20mm, and 4-32mm holes?
  A: Included are three step sizes: 4-12mm, 4-20mm, and 4-32mm. This configuration allows you to drill first a pilot then larger diameters in a single bit, reducing wandering. The HSS Titanium Coated Step Drill Bit Set’s stepped profile provides smooth entry and consistent hole diameters in steel, brass, plastic, or wood.
• Q: What are the benefits of the titanium coating on these HSS drill bits?
  A: Titanium coating dramatically lowers friction, reduces heat buildup, and lengthens bit life. For the HSS Titanium Coated Step Drill Bit Set, this means faster material removal, less bit wear, and cleaner edges. The coating also provides corrosion resistance, helping maintain performance across multiple jobs.
• Q: Who should buy this set and can it handle metal, wood, and plastic projects?
  A: This set is perfect for both DIY enthusiasts and professionals who need versatile drilling options. The HSS Titanium Coated Step Drill Bit Set handles steel, brass, aluminum, wood, and plastic with consistent results. Its three sizes cover common projects from metal enclosures to cabinetry, making it a practical upgrade to any toolkit.
• Q: How does the three-size range improve drilling accuracy and efficiency?
  A: With three steps in one bit, you reduce the need to switch bits mid-project, minimizing misalignment. The stepped design guides the drill, improving accuracy when starting holes in metal or plastic. This also speeds up workflows, as you move from small to large diameters without repositioning the workpiece.
• Q: How is the set stored and transported?
  A: Portability is a key feature of the HSS Titanium Coated Step Drill Bit Set. It comes with a cloth bag for easy storage and transport, keeping bits organized and protected. When you’re on the job, this compact set fits into toolboxes, bags, or pockets for quick access.
• Q: How does the HSS Titanium Coated Step Drill Bit Set compare to standard bits for speed and durability?
  A: Compared with standard drill bits, the HSS Titanium Coated Step Drill Bit Set delivers faster cutting with less heat, thanks to the titanium coating. The HSS base material provides toughness, while the three-hole-size range reduces the need for bit changes, delivering longer life and more reliable holes in metal, wood, and plastics.
