Predator Cobalt Stubby Drill Bits – Built for Tough Metal.
Predator Cobalt Stubby Drill Bits—also known as screw machine length—are built for precision drilling in the hardest metals out there. Shorter length, more control, and serious bite.
Manufactured to NAS 907J aerospace specs, every bit is fully ground and gold-finished for strength, accuracy, and long life. The stubby profile adds rigidity, so you get less flex, less breakage, and more control, especially in tight spaces or under heavy feed pressure.
The 135° split point drills fast, stays on center, and eliminates the need for a pilot hole. Cleaner holes. Less walking. Less wasted time.
If you’re working in metal fab, aerospace, automotive, or heavy industry Predator Stubby Cobalt Bits are the upgrade your shop needs. They don’t back down when the heat’s on.
