7 Blade Drill Bit Benefits

  • Higher drilling efficiency: Seven cutting blades distribute impact and rotation forces evenly, improving rock breaking speed, reducing energy loss, and maintaining consistent penetration rates.

  • Improved hole stability: The multi-blade design enhances balance during drilling, minimizes vibration and deviation, and delivers straighter, more accurate boreholes.

  • Longer service life: Wear is shared across multiple blades, lowering stress on each cutting edge, reducing damage, and extending overall bit lifespan.

  • Strong adaptability: 7 blade drill bits perform reliably in medium to hard rock formations, suitable for mining, quarrying, and foundation drilling.

7 Blade Drill Bit Applications

  • Mining drilling: Used for production and exploration drilling in medium to hard rock, providing stable penetration, efficient rock breaking, and reliable hole quality in underground and surface mining.

  • Quarrying operations: Ideal for quarry bench drilling, delivering straight holes, reduced vibration, and consistent performance when drilling limestone, granite, and other hard stone materials.

  • Construction foundation drilling: Suitable for foundation piling and anchoring projects, ensuring accurate hole diameter, stable drilling process, and dependable performance in complex ground conditions.

  • Geotechnical and exploration drilling: Applied in geological surveys and exploration work, offering controlled drilling, precise boreholes, and dependable results across varied formations.

Customize Your Desired 7 Blade Drill Bit

Blade design and geometry

We customize blade angles, profiles, and cutting edge layouts to match specific rock formations. By optimizing blade geometry, we improve penetration efficiency, reduce vibration, and enhance drilling stability while maintaining consistent hole quality during operation.

Material and heat treatment

We select suitable steel grades and carbide materials according to rock hardness and abrasiveness. Combined with optimized heat treatment processes, this ensures stronger wear resistance, improved toughness, and extended service life in demanding drilling environments.

Bit diameter and shank connection

We customize bit diameters, blade spacing, and shank types to fit different drilling rigs. Proper matching improves power transfer, reduces energy loss, and ensures secure connections for stable and efficient drilling performance.

Flushing system and debris removal

We design flushing holes and air or water channels based on drilling methods. Efficient debris removal improves drilling speed, prevents bit clogging, reduces heat buildup, and helps maintain consistent performance throughout drilling operations.
