1/8 In Cobalt General-purpose Drill Bit For Hard Materials

Discover the ARTU 1/8 in. cobalt general-purpose drill bit, engineered for both rotary and percussion drilling. It cuts through a broad range of materials—from metal and ceramic to masonry, glass, PVC, stone, and wood—with steady precision. A cobalt-tungsten carbide tip delivers exceptional hardness and heat resistance up to 2000°F, while a negative back grind helps prevent walking at entry. The chrome vanadium shank provides enduring strength and flexibility, and the bit meets ANSI standards for reliable performance.

Benefits: This drill bit minimizes downtime with a durable edge and the option to resharpen, extending life and reducing replacement costs. Its versatility lowers the need for multiple tools, delivering cleaner, faster holes across diverse projects.

• Cobalt-tungsten carbide tip delivers outstanding hardness and heat resistance for long-life cutting in tough materials.
• Broad material compatibility lets you work on metal, tile, concrete, glass, plastic, wood, and more without switching bits.
• Anti-walk design with a negative back grind ensures precise entry and minimizes wandering.
• Resharpenable edge allows quick restoration on a silicon carbide wheel to extend tool life.
• Rugged chrome vanadium shank delivers consistent torque transfer and durability; ANSI standard compliant.

Why This Drill Bit Stands Out: Built for professionals and hobbyists alike, it blends toughness with versatility. Expect reliable performance, cleaner holes, and longer service life across a broad spectrum of materials.
