Drilling bits for the mining industry

Used for rotary blast hole drilling with air flushing.

Utilized for pilot hole drilling during raise boring operations.

Utilized while blast hole drilling with downhole hammers. A splined joint of the shank improves reliability and joint strength and provides quick and easy tool change.

Applied for rotary drilling in strata with soft to soft/medium characteristics (f=1-5 in terms of professor M. M. Protodyakonov rock hardness scale) with air or air-water flushing. They are especially effective both for overburden drilling and coal exploration. VBM drag bit comprises three parts: a bit body, removable teeth and a back flow valve.

Applied for construction and mining industries and can be successfully used for exploration drilling, methane drainage borehole drilling and injection drilling. FDC bits comprises a steel body and polycrystalline diamond cutters (PDC), they are used for drilling both vertical and directional fullhole wells. Application of wear-resistant PDC cutters multiplies bit life and performance. Flushing through ports directed towards the well bottom efficiently cleans the hole and cools the bit.
