28mm 30mm Anchor PDC Bit
Symmetric Two‑Wing Cutting Structure
Symmetric double‑wing design ensures balanced force distribution, keeps borehole straight and avoids hole deviation. It greatly reduces bit sticking risk. Large‑size junk slots improve coal dust and rock cuttings evacuation, prevent bit balling and boost continuous underground drilling efficiency.
Heavy‑Duty Wear‑Resistant PDC Cutters
Impact‑resistant PDC cutters are optimized for coal seams, mudstone, shale and weathered sandstone. Balanced penetration rate and service life lower downtime caused by frequent bit replacement.
High‑Toughness Bit Matrix
Tough alloy steel matrix resists impact and extrusion under heavy vibration from underground bolting rigs. Anti‑crack and anti‑deformation performance fits both pneumatic and hydraulic roof bolter working conditions.
Complete Size Range & Custom Solution
Ready‑made diameters: 26mm, 27mm, 28mm, 29mm, 30mm, 32mm, 40mm, 42mm, 50mm to match various anchor bolt and anchor cable hole diameters. Custom PDC layout, matrix hardness and connection thread specifications are available based on your rock conditions.
Direct Factory Supply for Bulk Orders & Export
Strict production quality control from original manufacturer. Large‑volume export orders are supported. Relevant product inspection documents can be provided for mining project procurement and cross‑border wholesale.
