DTH Hammer and Bit Carbide Button Inserts for Drilling Hard Rock

Feature: 1:Tungsten carbide tips, inserts, buttons, wear parts for mining, rock drilling, oil exploration, geological prospecting, road digging, snow plowing and construction engineering. 2:Our durable carbide with excellent fracture resistance dramatically improve tool life with high penetration rates. The consistent performance and tolerance are mainly attributed to our pure raw materials and strict ISO quality control. 3:All of our carbide mining tips and inserts are made from virgin raw materials and HIP sintered for the top good quality and high performance. 4:Various sizes and styles are available here and we can also make the tips in any new design and sizes to meet our customers'requirement. Tungsten carbide buttons application The carbide button is sintered by coarse grained cemented carbide, with proerties of high hardness and good transverse-rupture strength, as well as corrosion resistance, resistance to acid and alkali, long service life. They are mainly classified as follows: the cutting tips used by cold pavement milling-planing machine, the cutting tips used by rotary digging machinery, the cutting tips used by coal digging machine, the cutting tips used by roadway and tunnel boring machine, the cutting tips used by trench excavator etc. They are widely used for crushing or milling rocks. Cutting tips are tools for rock digging widely used in mining and geotechnical engineering. Grade recommend Grade Density (g/cm3) Hardness (HRA) T.R.S (MPa) Application recommended YG6 14.95 90.5 1900 For coring crowns,electric coal drill bits,coal cutting picks,oil cone bits and scraping knife bits,used in geological prospecting,coal mining and oil well boring.

YG8C 14.8 89.8 2800 Mainly used for small and medium-sized drill bit tooth, and as a rotating exploration drill bush. YG11C 14.4 86.5 2700 Most used in the drill bit and rock bit used for cutting high hardness materials ball tooth. YG13C 14.2 86 2900 mainly used for rotary drill bit used for cutting high hardness materials in ball mill. YG15C 14 85 3000 Used in oil cone bit and soft in the hard rock digging cutting tools. YK05 14.9 90.5 2600 Mostly used as the buttons of small and mediumsized bits to cut soft and medium hard formations YK15 14.6 88 2750 Suitable to strips,conical buttons for rotary percussion-resistant geological prospecting buttons,cut soft and medium hard formations. YK20 14.5 87.5 2800 Primarily for the buttons and inserts of rotary percussion bits to cut medium-hard and very hard formations, YK25 14.4 87.2 2550 Primarily for the buttons and inserts of rotary percussion bits to cut medium-hard,hard,and very hard formations Application Tungsten carbide buttons types Button bits for coal mining These tungsten carbide button bits are mainly used for coal mining, coal cutting picks, electric coal drill bits, coal mining cutter picks, roadway excavation, rotary drilling for pile hole, pavement milling.Such as Bob's bit, Rotary bit,Digger button bit and so on. Gungnir Industry Ltd offer high performance button bit,and the quality reach the international top level. Carbide button bits for construction Such carbide button bits are mainly used for bridge pile foundation excavation, tunnel shield, urban road crossing, mining wear parts, high-speed railway, highway maintenance and the like. These products are complex in specification, with wide range of applications, stable and reliable quality. Carbide button bits for oil-field The button bits are mainly used for tri-cone drill bits for oil and gas fields excavation and large-scale open-pit mine .
