Grade MK6 Tungsten Cemented Carbide Buttons , DTH Carbide Button Bit for Mining
Advantage of tungsten carbide button
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.
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.
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 tips, inserts, buttons, wear parts for mining, rock drilling, oil exploration, geological prospecting, road digging, snow plowing and construction engineering,we all can provide.

Application of carbide button
Cemented carbide button bits is widely used in petroleum drilling, snow plow equipment, cutting tools, mining machinery, road maintenance and coal drilling tools.It is also can used as excavating tools for Tunneling, quarrying, mining and Construction. In addition, it can be applied as drill accessories for rock drilling machine and deep hole-drilling tools.
Production process of cemented carbide button
1, Soon after the order is confirmed, cemented carbide button products will start to prepare the RTP powder as per customer’s requirement with our wet-grinding machine
2, Before mass production, we need to do a trial pressing and sintering using every mould, and we check the appearances and the sizes of the samples with micrometer, projectors etc. to ensure that the requirements of the drawings can be met before batch production
3, Bulk production ,press the raw materials to shape blanks,and all cemented carbide button blanks must be passed by semi finished inspection,
4, Then sinter blanks to finish (HIP) and finished products inspection, we have 10 sets of vacuum sintering furnace and 2 sets of HIP in the factory ensure the best quality and production capacity.
5, 1). cleaning/tumbling is to make the cemented carbide button look more beautiful.
2).The cemented carbide button can be ground according to customers’ order to a tolerance of +/-0.05
