Down the hole (DTH) Button Bits

AME DRILL DTH Bit

Down the hole (DTH) button bits are widely used for mining, quarrying, construction, civil engineering, and water well drilling. Combining premium raw materials with advanced production technologies, we manufacture various DTH button bits to match all famous brands of DTH hammers, including Epiroc, Sandvik, Halco, etc. Also, following each client’s request, we design and manufacture different types of DTH button bits for their different rock formations and applications.

Bits diameter:

76 mm to 311mm

Bits shank style:

*We can offer more shanks according to customers’ requirements

Bit’s face design:

flat face, convex face, concave face, DGR (double gauge row)

Flat face (Spherical)	Flat face (Spherical + Ballistic)	Convex face (Spherical + Ballistic)	Convex face (Ballistic)	Concave face (Spherical)
Applications: For drilling in hard and abrasive rock.	Applications: For drilling in medium-hard too hard and moderately abrasive rock.	Applications: For drilling in hard and abrasive rock.	Applications: For drilling at high penetration rates in non-abrasive rock.	Applications: For drilling in medium har, maximum hole deviation control.

Bits with carbide shape:

hemispherical (round), parabolic (semi-ballistic), ballistic (conical);

Hemispherical buttons: Universal buttons for all rock formation, best suited to the hardest and very abrasive rock formation.	Parabolic buttons (semi-ballistic): Excellent penetration rate, but only suited to medium-hard and not so very abrasive rock formation.	Ballistic buttons: Similar to parabolic buttons, used for soft to medium hard and not so abrasive rock formation, excellent in penetration rate.
