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.
