High Durabilit PDC Bit for Marble
Marble and granite are high-hardness natural stones that cause rapid wear and tooth breakage of ordinary drill bits, greatly increasing the consumption cost of mine construction. Our
78mm 4-blade non-core PDC bits
are specially developed for high-hardness stone quarry working conditions, serving as durable essential tools for stone mining, horizontal cutting and cross drilling.
High Durabilit PDC Bit for Marble
Adopting
42CrMo alloy tempering process and integral casting technology
, the bit body greatly improves wear resistance, impact resistance and fracture resistance, maintaining stable working performance in hard granite and dense marble formation. The optimized spiral body reduces abrasive wear from stone debris and extends bit service life. The 4-blade balanced force structure ensures stable horizontal drilling and high hole forming quality. All sizes (75mm, 78mm, 80mm) fit 73mm drill rods with customizable male and female threads. As a direct manufacturer, we provide high-quality and cost-effective PDC bits, perfect for stone quarry enterprises to replace imported drilling tools and reduce operating costs.
