Troubleshooting Drilling in Masonry
Problem Solution
Core bit does not cut.
Material too hard for core bit.
• Choose a more appropriate core bit
(with softer segments).
Segments look glazed and polished • Drill in abrasive material to
re-expose diamond segments.
Dust accumulating in core bit.
Accumulating dust slows down the
drilling speed.
• Disengage drill bit regularly to
evacuate cuttings. Check filter on
dust extraction. Clean or replace
as required.
Rotating speed may not be
appropriate.
• Refer to the Maximum
Recommended Capacities for
proper speed ratings.
Segments wear too fast. • Choose a more appropriate core bit
(with harder segments).
• Reduce the pressure applied on
the core bit.
