3/16 In. Cobalt General-purpose Drill Bit

Introducing ARTU 3/16 in. Cobalt General-Purpose Drill Bit, a versatile cutter engineered to handle challenging drilling tasks with confidence. Built from a cobalt-infused alloy and paired with a tungsten carbide tip, it resists wear and stays sharp across metals, ceramics, glass, stone, and more. Its robust chrome-vanadium shank and optimized geometry support both rotary and hammer-style drilling, delivering true holes with reduced walk and effortless performance. This bit is ideal for fast, clean holes in metal, tile, concrete, glass, wood, and PVC.

Benefits and value: This bit minimizes downtime thanks to superior edge retention and heat resistance, enabling fast drilling through hardened materials without wobble or retry passes. Perfect for professional shop work, home projects, and installations that demand clean, accurate holes.

• Cobalt composition for heavy-duty metal drilling: A cobalt-infused core delivers exceptional hardness and longevity, ideal for metalworking and high-temperature applications.
• Tungsten carbide tip for wear resistance: Retains sharpness longer and endures temperatures that would dull standard bits.
• Self-centering, center-punch-free design: Reduces walking and ensures precise hole placement on tough materials.
• Negative back rake grinding for smooth entry: Optimizes cutting action to minimize chips and friction during drilling through hard composites.
• Parabolic flute, robust shank, ANSI-compliant: Fast debris removal with a reliable chrome-vanadium shaft and conforming to ANSI standards for compatibility.

Why this ARTU drill bit stands out: It combines toughness, versatility, and precision in a single tool, designed to tackle a wide range of materials from metal to masonry. With exceptional heat resistance and long life, it helps you complete professional-grade holes with fewer passes and less effort, making it a smart addition to any toolkit.
