🔧 What Is a Stub Drill?

A stub drill, also known as a short series drill, is shorter in length compared to standard jobber drills. This reduced length offers higher rigidity and less deflection, making it ideal for precise operations or when drilling thinner materials. It’s also preferred in CNC setups for its minimal runout and reduced vibration.
