Applications of Threaded Drill Bit

Drilling works for blasting duties in tunneling, construction, mining, quarrying, etc.

	Flat front: For drilling in medium to hard and abrasive rock
	Drop center: For drilling in medium hard, with maximum hole deviation control.
	Normal skirt: For drilling in very hard and very abrasive compact rock formations.
