Why Choose This Step Drill Set?

• Versatility at Its Best: With three different sizes (3-12mm, 4-12mm, and 4-20mm), you can effortlessly create holes in steel, brass, wood, plastic, and more. The precision of these drills ensures clean, burr-free holes every time.

• Titanium Coated for Excellence: The high-speed steel (HSS) construction is enhanced with a titanium coating, minimizing friction and heat for smoother drilling and extended tool life. Say goodbye to wear and tear and hello to consistent, quality performance.

• Designed for Precision: Each step is meticulously labeled with depth diameters, making your work precise and eliminating guesswork. The two-flute design not only speeds up drilling but also ensures cleaner cuts.

• Non-Slip Hex Shank: The unique three-sided shank design prevents the drill bit from slipping in the chuck, ensuring stability and safety during operation. It's compatible with a range of tools, including hand drills, bench drills, and even pistol drills.

• Cooling Efficiency: For optimal durability, especially during continuous use, water injection cooling is recommended. This simple step can significantly prolong the life of your drill bits, making them a reliable addition to your toolkit.

• Widely Applicable: Ideal for creating or enlarging holes in general-purpose materials, this set is not recommended for stainless steel or spring steel. It's perfect for tasks involving materials with general hardness, such as PVC plates or iron plates with a thickness within 3MM.

Practical Tips for Users:

• Maintain a consistent downward force without pressing too hard to avoid wear and potential annealing.
• Keep the drilling speed within the recommended range (260-400 for 3-12 and 4-12; 180-240 for 4-20) to achieve the best results.
• For prolonged drilling sessions, ensure adequate cooling to prevent overheating and damage to the bit.
