As there are more variables in core drilling than in any other type of cutting. Being competent in core drilling is the foundation of a good cutter.
-
Speed (RPM)
If the speed is too high the bit will polish. If the speed is too low
the job will take too long.
-
Power
Is necessary to maintain the proper cutting speed. Efficient cutting means
keeping the bit at the right speed.
-
Water
Not too little and not too much the right amount
removes slurry and keeps the cut clean.
-
Aggregate
You can't see it until you're done, but a good driller can
feel the right speed and pressure to cut varying types.
-
Steel
Slows the cutting process. Maintaining drill motor speed is important.
DON'T PUSH THE BIT TOO HARD !- MAINTAIN SPEED !
-
Bond Specs
Too hard and it takes too long. Too soft and it costs too much.
-
Proper Alignment
Is necessary for good bit life. This means the rig must
be properly anchored. A rig can be anchored with concrete anchors,
vacuum or a post jack. STANDING ON THE RIG IS DANGEROUS AND NOT ACCEPTABLE !
-
Core Rig Maintenance
Performance, speed and bit life will mean little if
your rig has bad shims, bearings and hold down devices.
