Litong manufactures high quality PDC bits which have been specially designed to withstand higher impact and abrasion. Our PDC bits are of premium quality being used extensively in water bore drilling, oil and gas exploration.

1. Dia.65mm 75mm 89mm 94mm, 110mm, 112mm 127mm

2. super hard material combined with diamond and hard alloy under high temperature

3. Polycrystalline diamond compacts

PDC drill bit is super hard material combined with diamond and hard alloy under high temperature. It not only has the advantages of hard and durable from diamond, but also has the advantages of high impact resistance and big blade from hard alloy. I t greatly improve the drilling efficiency and is the ideal drill bit for the drill operation of medium &hard as well as super hard rock.

The carrier of PDC bits is forged and pressed by first -class steel. Its mechanical capacity is strengthen by fully automatic vacuum heat treatment equipment.

The ordinary type adopts Chinese PDC as its blade, while the super-strong type adopts American blade by GE. Choosing proper type makes high ratio of performance and price.

Our PDC drill bits are widely used in all industries, such as coal mining, oil exploration, geological exploration, water and hydroelectric, railway and road, tunneling construction and so on.
