?Here we explain how to solve the most common problems that can occur when drilling with a diamond core drill bit.
| WHAT WE SEE ON THE DIAMOND DRILL BIT | POSSIBLE CAUSE | SOLUTION |
|---|---|---|
RELEASE OF SEGMENT | – Lack of cooling, decrease thickness – Excessive heat – Drill Jam – Loose rods | – Increase cooling – Check that the anchorage of the drill bit is correctly placed and without damage |
SEGMENT WITH DARK COLOR | – Lack of cooling – Excessive heat – Excessive speed | – Increase cooling – Slow down rotation speed – Switch to a mode of cyclic drilling |
SEGMENT INCLINATION (OUTSIDE / INSIDE) | – Abrupt start – Work at high power with the polished segment – Choose a segment too hard | – Drill softly – If possible, move the opening part. – If the movement is not possible, set the speed lower rotation – Put the drill bit as slow and smooth as possible |
CRACKS IN THE STEEL BODY | – Unequal wear out of the body of the nucleus as a result of core runout, lateral loads, impact – Overload during drilling – Drill Jam | – Change to a mode of smoother drilling or cyclic – Stop the drill and unblock the drill bit |
SEGMENT TOTAL OR PARTIALLY BROKEN | – Wrong fixation of the stand – Loose rods | – Set the stand |
FRICTION AT THE TUBE | – Thickness loss – Loose rod | – Set the stand – Cut |
LOW CUTTING SPEED | – Satin Segment | – Lower peripheral speed |
EXCESSIVE WEAR | – Lack of cooling – Low peripheral speed | – Increase cooling – Upload peripheral speed |
