For professionals in metalworking, construction, or manufacturing, a reliable drill bit isn’t just a tool—it’s a cornerstone of efficiency, precision, and long-term productivity. When every hole needs to be clean, every operation needs to be smooth, and every tool needs to withstand heavy use, the TiAlN Spiral Flute Step Drill Bit stands out as a game-changer. Engineered specifically for professionals, this drill bit combines premium materials, innovative design, and durable coatings to tackle even the toughest drilling tasks with ease.
At the heart of this drill bit’s performance is its high-quality construction. Crafted from high-speed steel with 5% cobalt content (HSS Co5%), it delivers exceptional hardness and superior heat resistance compared to standard drill bits. This means the TiAlN coated spiral flute step drill bit HSS Co5 can handle prolonged use at high speeds without losing sharpness or warping—critical for professionals who rely on consistent results day in and day out. Whether you’re drilling through thick metal sheets, rigid stainless steel components, or durable plastic parts, the HSS Co5% base ensures the bit maintains its integrity, reducing the need for frequent replacements and minimizing downtime.
Complementing its robust material is the TiAlN Spiral Flute Step Drill Bit’s spiral flute design—a feature engineered to enhance functionality at every step. The spiral flutes act as an efficient channel for chip removal, clearing away debris quickly and efficiently during drilling. This not only prevents clogging (which can ruin holes and damage the bit) but also reduces vibration as the bit operates. Less vibration translates to more precise holes, smoother drilling action, and less fatigue for the user—making even long drilling sessions more manageable.

To further boost durability and performance, the drill bit is coated with Titanium Aluminum Nitride (TiAlN). This advanced coating is a favorite among professionals for its exceptional wear protection and thermal stability. TiAlN forms a hard, protective barrier on the TiAlN coated spiral flute step drill bit HSS Co5’s surface, shielding it from abrasion, corrosion, and extreme heat generated during drilling. The result? A drill bit that lasts longer, maintains sharpness through repeated use, and performs reliably even in high-temperature environments—perfect for tackling tough materials like stainless steel, which tend to generate more heat during drilling.
Versatility is another key strength of the TiAlN Spiral Flute Step Drill Bit. While it excels at drilling and enlarging holes in metal and stainless steel (common tasks in automotive repair, metal fabrication, and industrial settings), it’s also highly effective for use with plastic. This multi-material capability makes it a versatile addition to any professional’s toolbox, eliminating the need to switch between different drill bits for different materials and streamlining workflow.


For professionals who refuse to compromise on quality, efficiency, or precision, the TiAlN coated spiral flute step drill bit HSS Co5 is more than just a tool—it’s an investment in better work. Its HSS Co5% construction, spiral flute design, and TiAlN coating work together to deliver consistent, reliable performance, while its versatility ensures it can handle a wide range of tasks. Whether you’re a seasoned metalworker, a construction professional, or a manufacturing technician, this drill bit is designed to meet your needs and exceed your expectations.
Don’t settle for subpar drill bits that slow you down or fail when you need them most. Upgrade to the TiAlN Spiral Flute Step Drill Bit and experience the difference that professional-grade engineering can make in your work.
