75mm 3-Blade Concave Non-Core PDC Bit
Tailored for lightweight construction scenarios such as small and medium-sized stone quarries, refined marble and granite cutting, and shallow horizontal drilling, our factory launches the professional
75mm 3-blade concave non-core PDC bit
. Different from dense 4-blade, 5-blade and cross-structure drill bits, this bit adopts a
streamlined 3-blade concave design
with larger blade spacing and lower drilling resistance. It is a high-efficiency special drilling tool for 75mm horizontal transverse drilling, widely used in mine cross-hole drilling, stone cutting and small tunnel drilling, solving the industry difficulty of slow penetration and high resistance in small-diameter horizontal drilling.
The symmetrical 3-blade concave structure features a lightweight design and larger hollow working space, which effectively reduces the load of horizontal drilling rigs and realizes quick startup and smooth drilling without stalling. The optimized multi-channel
balanced water outlet system
provides uniform cooling for all PDC cutters, quickly dissipates high drilling temperature, prevents tooth burning and premature wear, and greatly extends the service life of the drill bit. With wider and fully unobstructed concave slag discharge grooves, this bit achieves zero residue accumulation, efficiently discharging marble and granite rock powder and debris. It completely avoids hole blocking and bit jamming caused by reverse slag accumulation in horizontal drilling, maintaining stable and fast penetration speed for refined stone quarrying operations.
This 75mm 3-blade concave PDC bit supports
custom internal and external threads
, perfectly matching standard 73mm drill rods and compatible with all mainstream domestic and imported horizontal drilling rigs. As a professional direct manufacturer of mining drill bits, we provide customized processing, bulk production and fast delivery services. We offer low-energy consumption, high-efficiency horizontal drilling solutions for small and medium-sized stone mines and mining projects worldwide, helping customers reduce equipment load and construction costs.
