NQ2 High Quality Synthetic Wireline Impregnated diamond core bit

Country/Region	china
City & Province	changsha hunan

Product Details

The impregnated diamond bits are the most commonly useful bits in the mineral exploration industry, as they have the widest range of application. The carefully selected grades of high quality synthetic diamond are distributed in the depth of impregnated bit's matrix series. The matrix layer of the crown contains a uniform distribution of these crystals that are embedded in a powdered metal bond. The matrix of our impregnated bits is designed to expose new diamonds to the bits' cutting face as wear occurs. Fast penetration rate is maintained as a result of this action.

Features

1:the impregnated diamond core bits features drilling speed and long service life

2:the design of more cutting edges makes drilling progress smoother

3:during the manufacturing process, the diamond is free erosion and fully utilized

4:the impregnated diamond core drill bits are of various configurations and meet various needs of local conditions

5:it offers the most widely-used bit matrices as well

6:with various specifications, our series matrix range provide an easy selection and reliable foundation for your drilling needs
