1/2 In Cobalt General-purpose Drill Bit - Heavy-duty All-purpose Bit

Showcasing the ARTU 1/2 in Cobalt General-Purpose Drill Bit, built for demanding drilling tasks across a wide range of materials. The advanced cobalt alloy tip paired with a hard tungsten carbide edge delivers unmatched wear resistance and sustained cutting performance under heavy use. Featuring a rugged chrome-vanadium steel shank and precision-ground geometry, this bit maintains true alignment for clean, accurate holes when transitioning from metal to tile, masonry, glass, or wood. Its design emphasizes reliability, reducing wandering and chatter so you complete projects faster with less effort.

Versatile performance for every project: The cobalt composition with a precision tip minimizes wandering and ensures stable entry, enabling smooth starts on challenging substrates. It excels in metalworking, tile installation, masonry drilling, and woodwork, helping you finish tasks faster with less effort, and it remains cool under heavy use thanks to efficient heat dissipation.

• 1/2 in Shank: Standard size fits most drill chucks for quick changes and consistent grip, supporting versatile use with common equipment.
• Cobalt & Tungsten Carbide Tip: Delivers exceptional hardness and heat tolerance up to 2000°F, reducing premature wear when drilling through tough materials.
• Multi-Material Capability: Efficiently handles metal, ceramic tile, concrete, glass, wood, PVC, and more with a single, durable bit.
• Self-Centering Tip & Negative Back Grind: Keeps entry precise by preventing wandering and ensuring clean holes on slick or uneven surfaces.
• Flute Geometry & Resharpening: Flat-bottom parabolic flute promotes fast chip removal, and the bit is easy to resharpen on a silicon carbide wheel.

Why This Drill Bit Stands Out: Built to endure demanding jobs, this bit delivers reliable performance across materials while minimizing tool changes. Its robust construction, versatile capability, and long life make it an essential addition for professional shops and serious DIY projects. For upgrades to your toolbox, it provides predictable holes, reduced chatter, and increased efficiency on every project.
