Details
- Jobber length drill bit has a midrange drilling depth for general-purpose applications

- Self-centering 135-degree split point penetrates hard material without a pilot hole and produces small chips to reduce clogging
- Extra thick web provides increased strength and rigidity compared to standard drill bits
- Made in the USA
