Medium compres-sive strengths up to 30,000 psi (207 mpa). These include shale, mudstone, sandstone, limestone and some siliceous conglomer-ates.9 7/8" (251 mm) HDX30FEATURES / BENEFITSPatented Charger® HDX® Technology Dual Seal Bearing SystemKevlar® coated excluder seal technology protects the primary seal assuring long bearing life. The weight and rotation speed capacities are dramatically increased through the use of Pfi nodal® bearing sleeves.Trucut Gage InsertsEffi ciently cuts the gage to minimize fatigue and heat checking induced breakage. Patented gage system uses Semi Round Top inserts on gage, alternating with either HDX sculptured or HDX off gage inserts.W FeatureA patented process applies proprietary hard material to areas of the cone that are prone to erosion to prevent insert loss.HDX Gage InsertsCrest geometry and TCI (Tungesten Carbide Insert) grades help improve gage wear rates in abrasive conditions. HDX Vector InsertsUnique sculptured shape and TCI reduce potential breakage through side loading.Maximum Leg and Shirttail ProtectionSemi Round Top inserts to protect the leg and shirttail in dirty hole conditions and long service hour environments.PRODUCT SPECIFICATIONSSize 9 7/8" (251 mm)Nominal Diameter 10.140" (257.6 mm)Type HDX30 (IADC 547)DESIGN SPECSBearing Type Sealed FrictionInner/Gage/Trucut Rows 7/3/3Inner/Gage/Trucut Inserts 82/46/46Pin/Bit Connection Types 6 5/8" API OPERATING PARAMETERSWeight on BitLb - Min. to Max.
