FAQ:
1.What is the general delivery time?
15 working days for DTH bits.
20-25 working days for DTH hammer
3-5 working days for ex stock items.

A: As KINGDRILLING sells directly to consumers without a distributor, they can offer the greatest price.
3. How do I choose the appropriate head face for my DTH drill bit?
Concave: Ideal for drilling deep wells in a range of formations and for maintaining hole perpendicularity.
Convex: Good drilling efficiency, moderate borehole perpendicularity, and suitable for developing strata with a moderate degree of hardness.
Flat drilling is ideal for tough strata, especially those with fractures, proper fracture spacing, and a borehole that is perpendicular.
4. Features of the product
Innovative electron-hydraulic forging hammers are employed to forge kingdrilling DTH tools, while a multipurpose furnace heat treatment regulates the harness process.
