FEATURES: 
1. Faster drilling with the double-pointed segments provide incredibly fast drilling speeds
2. Fast seating and reduced vibration, the double-pointed tips penetrate quickly, and hold a straight drilling path to reduce side drag
3. Reduced vibration improves drilling efficiency and bit life
4. Improved cooling and slurry removal the double pointed segments increases water flow to reduce heat and removed slurry more efficiently
