15 000 bits yr-1,Technical edge: vacuum-melt 4330V cones → five-axis machining → 285 BHN bulk + 58 HRC tooth tips;metal-face seal lab-rated 180 °C, 250 h.https://kbjzbitpdc.com
AISI 4145H or 4330V forgings are austenitized, quenched and double-tempered in vacuum furnaces to 285–321 BHN, giving 25 % higher yield strength than API minimums and preventing cone cracking under high WOB.https://kbjzdrillrig.com
TCI inserts are 16–19 % cobalt, 0.8–1.2 µm WC grain; hot-isostatic pressing (HIP) eliminates micro-porosity, raising transverse-rupture strength to >3 200 MPa for hard-rock formations.https://kbjzbit.com
Diamond-enhanced cutting structure,Select gauge rows are overlaid with 1.2 mm synthetic-diamond compacts, reducing gauge wear rate by 40 % and keeping bit diameter 97 % of nominal after 120 rotating hours.https://kbjzpdc.com
Metal-faced seal systems,Two-piece “cone-seal + throat-seal” geometry uses tungsten-carbide-coated mating faces and HNBR elastomers rated 180 °C; lab tests show 30 % lower friction torque than conventional elastomer seals.https://kbjzpdcdrillbit.com
