Troubleshooting

Cause
Hard bonded segment!
Segment too big surface
Too fast RPM!
Drilling in steel!
Drill bit worn out!
Diamont grains pressed into the binding!
Segment surface is daubed with material
sludge
Segment surface is daubed with steel chips
No free cut because of side wards wear-out of
segments!
Soft bonded segments!
Segments to narrow!
Too low RPM!
Drill bit is deformed!
Drill bit out of true!
Abrasive material!
Poor water flow!
Loose material (cut steel or aggregate is
blocking the drill bit or between drill hole and
drill bit!
Drill rig was displaced during drilling (loose
fastening)!
Misaligned drill hole guidance of drill rig has
too much clearance!

Blunt drill bit
Use segments one class softer bonded
Attach a drill bit with less segments or reduce the
rpm an increase the feed compression.
Use lower gear.
Use lower gear and reduce feed and increase
water flow.
Replace with a new one.
Sharpen drill bit in sharpening plate, work with low
feed.
Increase the water flow, resharp the segments
Reduce the speed, increase the water flow,
resharp the segments
Replace the drill bit and have the drill motor
spindle checked.
Excessive wear of segments
Use segments one class harder bonded or
increase rpm and reduce the feed compression
Use drill bit with wider segments or reduce feed.
Shift the higher gear.
Change drill bit for a new one and bring worn drill
bit for rebalancing. Check drill stem and adjust or
replace it. Do not use deformed drill bits - it is also
wearing out the drill motor.
Change drill bit and bring worn drill bit for re-
balancing.
Use segments one class harder bonded. Increase
the water flow and the speed.
Increase the water flow in order to remove
abrasive slurry around segments.
Drill bit is stuck
Apply wrench and rotate drill bit in both directions
while drill bit is under tension. Disconnect drill bit
from the drill motor and drill over with a larger
sized drill bit.
Disconnect drill bit and remove. Break and pull the
core. Start again with improved fastening of the
drill rig. If drill hole is misaligned, drill over with a
larger sized drill bit.
Disconnect the drill rig, adjust guidance. Start with
a new hole or wash over. Do not enter the old drill
hole.
