Product Overview:
💎 Introducing our premium HSS Step Drill Bit Set, available in three versatile sizes: 3-12mm, 4-12mm, and 4-20mm. Each bit is expertly crafted from high-quality High-Speed Steel (HSS), ensuring durability and longevity while offering exceptional performance across a range of materials.
Excellent Material Compatibility:
🪵 These step drill bits are designed to effortlessly cut through an array of materials, including steel, brass, wood, and plastic. Their titanium coating significantly reduces heat generated during drilling, making them perfect for extended use.
🛠️ Precision Engineering:
🔍 Each drill bit features a heat-treated and highly polished surface, delivering perfectly round holes with each use. The innovative two-flute design enhances cutting efficiency, allowing for faster, smoother, and cleaner results. Each step on the bit is clearly labeled with its corresponding diameter, simplifying the drilling process.
🏆 Enhanced Performance Features:
🔒 The 3-sided shank design prevents slippage in the chuck, providing a secure grip during operation. This stability is essential for achieving the best results, and it is further complemented by the drills’ ability to perform deburring, chamfering, cutting, and expanding holes.
Compatibility with Power Tools:
😎 This drill bit set is versatile and compatible with a variety of drilling tools, including pistol drills, hand drills, charging drills, and bench drills. For optimal performance, we recommend using water injection cooling while drilling, which effectively extends the service life of the bits, especially during prolonged use.
🌿 Speed Recommendations:
User Guidance:
⚡ It's important to note that as the outer diameter of each step increases, so does the cutting resistance and linear speed. Due to the short inclined edge of merely 1mm, excessive feed speed during drilling may lead to the cutting edge wearing down. We recommend applying a downward force while maintaining a controlled pressure to avoid premature edge abrasion.
Suitable Materials:
🪵 The step drill bits are ideal for workpieces with general hardness, such as wood, plastic, PVC, and iron plates with a thickness of up to 3mm. Please remember that these bits are not suitable for stainless steel or spring steel as they are not intended for use on hardened materials.
