- Made from premium high-speed steel for increased durability
- 135-degree split-point tip starts drilling immediately with less force and eliminates "walking" across the work surface
- Rubber over-molded case has automatic indexing for easy bit access and identification. Removable cartridges are easy to carry to and from worksite
