In the world of drilling and machining, achieving clean, professional results is non-negotiable. Whether you’re a seasoned professional or a passionate DIYer, the right tool can turn a tedious task into a smooth, efficient process. The TiCN Coated HSS 90° Countersink Drill Bit with 3-Flute Round Shank is engineered to do exactly that, combining innovative design with advanced materials to redefine precision in countersinking, chamfering, and deburring.


At the heart of this drill bit’s performance is its triple-flute design. This clever feature ensures smooth, efficient chip removal, preventing clogs that can slow down work or leave rough, uneven finishes. Whether you’re working with metal, wood, or plastic, the flutes clear away debris effortlessly, resulting in chatter-free cuts that look polished and professional. No more stopping to clean out chips or dealing with jagged edges—this drill bit keeps the workflow steady and the results consistent.
Durability is a standout feature, thanks to its high-speed steel (HSS) body and titanium carbonitride (TiCN) coating. HSS is renowned for its strength and ability to maintain sharpness even under high temperatures, making it ideal for tough materials like metal. The TiCN coating takes this a step further: it enhances the bit’s hardness, making it resistant to wear and tear, while reducing friction between the bit and the material. Less friction means less heat buildup, which not only protects the bit from damage but also prevents warping or discoloration in heat-sensitive materials like plastic or softwoods. The result? A tool that lasts longer and performs better, project after project.
Versatility is another key advantage. This drill bit is designed to excel at a range of tasks—from deburring rough edges to chamfering holes and countersinking screws so they sit flush with the surface. It works seamlessly across materials, including metal, wood, and plastic, making it a go-to tool for everything from furniture assembly to metal fabrication.


Compatibility is never a hassle, thanks to its standard round shank. It fits most drills and drill presses, so you won’t need to invest in specialized equipment to use it. This ease of use makes it accessible to both professionals with well-equipped workshops and hobbyists with basic tools.
For anyone seeking a tool that delivers precision, durability, and versatility, the 3-flute TiCN countersink bit is a game-changer. It doesn’t just get the job done—it elevates the quality of your work, ensuring every cut is clean, every edge is smooth, and every project meets the highest standards.
