Surface-Set Diamond Core Drill Bit Hmlc For Concrete / Granite /
Stone
Specifications
1. Good quality and long working life
2. High Quality Natural Diamond
3. Reasonable price
Notice :
To select the right bit for the job, assess the speed and power of
your drill for the size and depths of the holes to be drilled and
assess ground conditions such as rock type/formation and down-hole
conditions.
Size:
SINOCOREDRILL bits are available in all standard drilling sizes .
Also, non-standard sized bits can be produced according to
requirements from clients.
Crown Height:
SINOCOREDRILL offers crown impreg depths of 9mm, 12mm, and 16mm
.The taller crown heights provide improved bit stability and
reduced vibrations, enhancing bit life and performance.
Waterways:
Various waterways are available for diamond impregnated bits.
Differing waterways allow for better flushing in various ground
conditions and drilling systems.

reaming shells, casing bit, casing shoe bit, corelifter, corelifter
case, core barrel assembly, inner tube head assembly, over shot,
hoist plugs, drill rod, casing pipe etc.
Advantages :
Surface-Set diamond bits are primarily recommended for use in
drilling relatively soft, abrasive, unconsolidated formations that
are not effectively drilled by impregnated diamond bits.
They are also recommended for use in drilling harder formations
where the available rotational speeds and bit loads are
insufficient to use impregnated diamond bits due to drilling
equipment limitations.
