*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.
