Description

Product Description

The candle-shaped carbide tip and thinner edge allow for sharper drilling and improved drilling speed. The center point of the carbide tip provides excellent positioning performance, and allows for drilling close to a true circle. The center point prevents wick from shaking during perforation, reducing vibration burden during work.
