Precision BQ NQ HQ PQ Rod Shoe Bit Diamond Core Drill Bits For
Available Size: HQ
Brand Name: yaheng
feature: High drill speed
1. 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.
2. Size: bits are available in all standard drilling sizes . Also,
non-standard sized bits can be produced according to requirements
3. Crown Height: 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.
4. Waterways: Various waterways are available for diamond
impregnated bits. Differing waterways allow for better flushing in
various ground conditions and drilling systems.
5. Matrix:impregnated bits matrices can be selected by our engineer
according to ground conditions at client's work site.
standard Q threads as well as thread types required by clients are
The BQ / NQ / HQ / PQ rod shoes bits are designed to drill in
casings or rods in difficult over burden material to position the
rods or casing in the drilling hole. The interior is smooth and
sufficiently large enough to allow free passage of coring equipment
such as bits, reaming shells core barrels and drill rods. They are
manufactured to withstand difficult drilling conditions: for
example, unconsolidated overburdened or broken abrasive materials.
Reaming Shells are used together with Core Bits, maintaining the
hole size and improving drilling stability.
1. High Penetration Rate
2. High Rotation Speed
3. High Performance
4. Long life drilling
5. High strong resistance to abrasion
