LOSS OF DRILLING ABILITY

Causes:
• Incorrect choice of diamond segments;
• insufficient power of the drive;
• overheating of segments during brazing.
PARTIAL OR TOTAL BREAKAWAY OF SEGMENTS

Causes:
• The drive stand base is not anchored;
• the reinforcement armature is loose during cutting.
FACE RUN-OUT

Causes:
• Wear-off of the spindle’s bearings;
• backlash of support stand base;
• deformation of the core body or extension piece.
JAMMING OF THE DRILL BIT DURING DRILLING

Causes:
• The drive stand base is not anchored;
• the reinforcement is not fixed during drilling, not enough water supply.
BENDING OF THE SEGMENT TO THE CORE BODY (INSIDE, OUT)

Causes:
• Excess feed force; the reinforcement armature is loose during cutting;
• not enough water supply.
FAST WEAR OF THE SEGMENTS

Causes:
• Incorrect choice of diamond segments;
• not enough water supply;
• excess feed force;
• overheating of segments during brazing.
BREAKAWAY OF SEGMENTS

Causes:
• Wear of the core;
• jamming during drilling;
• unfixed reinforcement;
• overheating.
JAMMING OF THE CORE SAMPLE

Causes:
• Breakdown of the core sample during the drilling process; not enough water supply;
• lack of inner overhang of the diamond segments on the core body;
• unfixed reinforcement in the drilling zone.
