Introducing the Stinger Black™ Turbo Core Bits
When drilling through some of the toughest surfaces in the industry, you need a tool that doesn’t just get the job done—it makes it easier, faster, and cleaner. That’s exactly what the Stinger Black™ Turbo Core Bits were engineered for.
Designed specifically for professional fabricators, these core bits combine turbo-segmented cutting edges with vacuum-brazed protection, giving you the perfect balance of speed, control, and durability. Every hole is drilled with precision, reducing blowout on the surface and minimizing chipping, even on fragile edges.
Whether you’re working in granite, engineered stone, quartz, or other dense materials, the Stinger Black™ Turbo Core Bits are built to deliver consistent performance job after job.
Key Advantages
-
Turbo Speed Meets Clean Cutting
The turbo-segmented rim ensures rapid drilling while maintaining sharp, clean edges that require little to no finishing. -
Durability That Lasts
With a vacuum-brazed protective layer, these bits resist premature wear, extending tool life even in high-demand shop environments. -
Wet or Dry Flexibility
Equally effective in wet or dry drilling applications, giving fabricators more control and flexibility on the job site. -
Universal Fit
Standard 5/8″-11 arbor fits most angle grinders, making it easy to integrate into your existing setup without special adapters. -
Comprehensive Size Range
Available in diameters from 1″ to 4″, including specialty increments, so you have the perfect bit for sink cutouts, faucet holes, and utility openings.
Performance You Can Trust
Every Stinger Black™ Turbo Core Bit is tested to meet the demands of high-volume fabrication shops. By combining cutting speed with edge protection, these core bits not only save you time but also reduce costly mistakes caused by chipped or cracked stone. That means smoother workflows, faster installations, and happier customers.
The result? Professional-grade holes drilled with confidence—every single time.
