Acker - Model DCDMA -M -Diamond Coring Bit

The DCDMA "M" Design core barrels and bits are used when coring soft, friable or broken formations. They are available with conventional waterways or bottom discharge design. Bottom discharge bits have internal water ports that permit the water to bypass the core and prevent erosion of soft materials. Grit facing strips are available for coring in very abrasive formations and to avoid excess wear on the bit body.
