Thread Button Bits Thread Drill Bit

 

Thread Button Bits Thread Drill Bit are a type of down-the-hole hammer bit used for drilling in extremely hard rock formations. As the name suggests, they have a threaded pin connection on the rear shank that screws directly into the drill rods.

 

The bit body is made of hardened steel alloy to withstand the pounding forces from downhole hammer action drilling. Instead of traditional cone cutters, thread button bits have a series of button-shaped tungsten carbide cutters inserted directly into the face of the bit body.

 

These durable cutter buttons are angularly positioned in concentric circles and rows across the bit face. Their self-sharpening design continues to break chips of rock away even after becoming severely worn.

 

The buttress-thread shank provides a robust connection between the bit and drill steel. This transfer of rotational torque and percussive impacts allows Thread Button Bits Thread Drill Bit to deliver class-leading rates of penetration, often doubling productivity versus standard tri-cone designs.

 

Ideal for extremely abrasive formations like granite, diorite and basalt, Thread Button Bits Thread Drill Bit minimize drill stalls. Their extra-large cutter capacity penetrates through hard layers with less need for frequent bit changes that slow drilling progress.

Thread Button Bits Thread Drill Bit is a specialized type of down-the-hole hammer bit used for efficient drilling in extremely hard rock formations. They feature a high-strength alloy steel bit body with a threaded male pin shank on the rear end for direct connection to the drill steel.

 

The bit body is precisely machined on CNC lathes to withstand the punishing impacts from percussive drilling. Its internal structure is engineered to effectively transmit rotational torque as well as withstand compressive and tensile stresses. Hardened tool steel grades like D2 or M4 are commonly used.

 

Around the face of the Thread Button Bits Thread Drill Bit body are inserted rows of self-sharpening tungsten carbide cutters, also known as button cutters. These are either brazed or pressed into pre-formed pockets at optimized radial positions and angles. Their spherical geometry and ultra-hard compositions continue to bite and chip away rock even when worn down.

 

Button cutters are manufactured using powder metallurgy techniques. Tungsten carbide powder is sintered under extreme heat and pressure to form near-indestructible cylindrical blanks. These undergo precise grinding and shaping before application onto the bit face.

 

Quality control is stringent. Cutters are x-rayed for void-free structures while blanks undergo destructive testing to exceed 250 HRA hardness minimums. Fully assembled bits are also load tested to ensure cutter retention and structural integrity meet or exceed OEM specifications.
