Product Details

Features:

Thread drill bits are crafted using premium alloy steel bars and tungsten carbides, ensuring their exceptional quality and durability. By undergoing a meticulous heat treatment process, our drilling tools are capable of withstanding the most rigorous rock drilling requirements, while also minimizing energy loss during the drilling process. Furthermore, we offer the flexibility to create customized thread button drill bits that cater to specific drilling applications. These tailor-made drill bits are designed to efficiently drill through various types of rock, including soft, loose-medium, and hard rock formations.

Face Design	Application
	Flat face button drill bits are suitable for all rock conditions, especially for the rock with higher hardness and higher abrasiveness. Such as granite and basalt
	Convex Face button bits are designed for fast penetration rates in softer rock.
	Drop center button drill bits are mainly suitable for the rock with low hardness, low abrasiveness, and good integrity. The bits can drill straighter holes.
	Normal Skirt For drilling in very hard and abrasive rock formations.
	Retract Skirt For drilling in loose,broken or fissured rock where it is difficult to retract the drill string due to the hole collapse.

Button Shape
	R：Round Utility carbide shape. Stong configuration against carbide fracture.
	B:Ballistic Higher penetrating carbide shape than Semi ballistic shape. Recommended for soft rock.
	BB：Semi Ballistic Combined wear resistance and high penetration rate. Recommended for medium-hard rock with moderate abrasitivity.
	SA:Spike Highest penetrating carbide shape. Weak configuration against carbide fracture. Recommended for soft to medium-hard work.
