Premium alloy steel for skirts;
Skirts are nitriding-processed, featuring better wearing quality;
Complete sizes and specifications, compatible with most mainstream-branded DTH hammers.

Applications

Mining, quarrying, water well drilling, geothermal well drilling, foundation piling, etc.

DTH Bits Shank Identification

DTH bits head design and selection

Flat front: Spherical buttons

Applications: For drilling in hard and abrasive rock

Flat front: Spherical gauge buttons, Ballistic front buttons.

Applications: For drilling in medium hard to hard and moderately abrasive rock.

Convex front: Ballistic

Applications: For drilling at high penetration rates in non abrasive rock.

Concave front: Ballistic

Applications: For drilling in medium hard, maximum hole deviation control.

Button shapes selection

Hemispherical button Universal buttons for all rock formation, best suited to hardest and very abrasive rocks formation

Parabolic button (semi-ballistic) Excellent penetration rate, but only suited to medium hard and not-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

Note:

1. Diameters above are only our standard configurations, other diameters are also available upon request.
2. The unit weight for each size is for reference only.
3. Face design, buttons shape, buttons configuration and flushing holes number must be confirmed when confirming the order.
4. Please be cautious when ordering bigger-diameter button bits since they might be oversized.
