- The 8% cobalt content maintains a sharp cutting angle and gives 4x longer service life compared to DEWALT's black oxide blades.
- Optimized tip and spiral geometry gives 2x faster penetration compared to DEWALT black oxide bits and removes drilling waste faster and reduces heat generation
- The stronger center provides 2x better break resistance compared to DEWALT's black oxide blades
- The non-wandering tip enables easier penetration of all surfaces
