Fully Ground Spiral Groove
Clears particles quickly, decreases friction and heat for a faster and cooler drilling performance.

Anti-Slip Triangular Handle
The anti-slip triangular handle design makes the electric drill clamp more tight and the drilling will not slip.

135° Split Point
Best for portable drills. Reduce drill walking, require less force than 118° point.
Self-centering split point allows you to drill directly to the size needed without any pre-drilling.
