The embedded PDC cutter configuration provides improved drilling efficiency and wear resistance, making this drill bit particularly suitable for quarrying, surface mining, and medium-diameter production drilling in abrasive rock conditions.
Product Description
The DHD340-115 DTH hammer bit features a convex face design with dome carbide buttons and DHD340 shank. Engineered for water well, mining, and construction drilling, it delivers excellent penetration rates in soft to medium-hard formations with low to medium air pressure.
Embedded PDC Cutters for Faster Penetration and Longer Bit Life
The DHD340-115 DTH drill bit is equipped with strategically embedded premium PDC cutters to improve wear resistance and maintain excellent drilling efficiency in quarrying and mining operations. Positioned around the gauge area, the PDC cutters reduce edge wear and help preserve hole diameter accuracy throughout continuous drilling.
Designed for medium-diameter blast hole applications, this bit combines durable dome carbide buttons with embedded PDC cutters to achieve faster penetration rates and more consistent drilling performance. The reinforced cutting structure minimizes premature wear, extends service life, and reduces replacement frequency, making it an efficient solution for quarrying, surface mining, and other demanding rock drilling projects.
Features
· Convex Face Design – All-around application bit face designed specifically for medium hard and homogeneous rock formations. Provides good hole deviation control and good flushing capacity.
· High Penetration Rate – Classic design for soft to medium hard rock formation which is not so abrasive. Excellent penetration rate in soft to medium-hard formations with low to medium air pressure.
· Steel Wash Resistance – Most resistant to steel wash among face designs, reducing load and wear on gauge buttons.
· Dome/Hemispherical Carbide Buttons – Universal buttons for all rock formations, best suited to hardest and very abrasive rock formations.
· YK05 Tungsten Carbide Grade – Premium YK05 carbide inserts deliver superior wear resistance and impact toughness.
· DHD340 Shank Type – Compatible with DHD340A series DTH hammers for reliable performance.
Advantages of Embedded PDC Cutters
· Embedded premium PDC cutters for enhanced gauge protection
· Fast penetration in quarrying and mining applications
· Excellent wear resistance in abrasive rock formations
