Super Strong Hard Rock PDC Anchor Drill Bit
High Impact Resistance
Spherical PDC Cutters
Small Diameter 25-42mm
Product Overview
The Super Strong Hard Rock PDC Anchor Drill Bit features a two-wing full-face design, specifically developed for high-hardness, fractured, and complex rock formations. It is ideal for small-diameter rock drilling applications such as coal mine support and tunnel engineering.
Designed for formations with Protodyakonov coefficient 8＜F＜12, this bit utilizes premium spherical polycrystalline diamond compact (PDC) cutters to enhance impact resistance and wear resistance, ensuring stable drilling performance under complex working conditions.
Note: F is the Protodyakonov coefficient, a key indicator of rock hardness in the mining industry.
