1 The drill guide is good.
2 Paul diameter spiral arc cutter wing.
3 Stability and strong ability to drill cutting
1. Ports on bit are also optimally designed to prevent erosion of water courses inside the bit
2.Hydraulic system of the bit is optimized using dynamic flow pattern simulation technology to enhance cleaning and cooling effects of the bit to effectively prevent bit from balling.
3.Cutting structure is force balanced, bit blade is asymmetrically designed, and spiral blade and spiral gage are also designed so that the load on bit is balanced which resulting better stability of the bit.
