80mm 5-Blade Concave Non-Core PDC Bit
Optimized for high-frequency horizontal drilling, stone cutting and mining operations in marble and granite quarries, our factory launches the upgraded
80mm 5-blade concave non-core PDC bit
. Different from traditional 4-blade and cross-structure drill bits, this bit adopts a unique
5-blade concave arc structure
, specially designed for horizontal rig transverse drilling working conditions. It effectively solves common problems of traditional bits such as poor slag discharge, uneven water output, slow penetration in hard rock and unstable drilling, ideal for large-scale drilling operations in hard stone mines.
The symmetrical 5-blade concave design disperses drilling pressure evenly and enhances the bearing capacity of the bit. It is resistant to tooth breakage and wear when drilling high-density granite and hard dense marble, delivering far better stability than conventional drill bits. The optimized concave groove and multi-channel water outlet structure realize
all-round balanced water circulation
, which cools the cutting surface evenly and rapidly, avoiding high-temperature ablation and aging of PDC cutters and greatly extending the bit service life. The widened concave slag discharge grooves quickly discharge stone debris and rock powder without residue accumulation or hole blockage, eliminating jamming and drilling stagnation in horizontal drilling and maintaining fast and stable penetration speed.
