Steel Down The Hole Hammer Bits Shank Diameter 165mm With 2 Flushing Hole

QL60 Shank Diameter 165mm DTH Hammer Flat Face Ball Drill Bit With 2 Flushing Hole

Adriller Drill Bit

Specific heat treatment standards and special "stress relief" processes ensure consistent performance.

Adriller DTH hammer bits are designed for maximum performance and hole cleaning ability and high penetration rate.

.

Description:

The characteristics of high pressure series DTH hammer:

Deliver maximum energy to drilling bit, which enables fast drilling speed and low air consumption due to the special inner structure of the DTH hammer series designed according to the newest rock drilling theory. Deliver smooth performance and long service of the DTH hammer series due to the high quality tungsten carbide steel materials and the advanced processing technology. Low problem rate and easy maintenance due to the simple, reliable and easy assemble and disassemble inner structure of hammer.

According to your request,the top sub can be made into two spanners, and put protection buttons. An air controlling hole can be drilled on the check valve to provide more efficient cuttings discharge.

Applications:

The Service Life Of Rock Drill Bit Is Determined By The Inherent Quality Of The Product Itself And The Scientific Method Of Use. The Quality Of Therock Drill Bit Itself Is Inferior. No Matter How Carefully And Scientifically Used, It Cannot Be Used At a High Level. a Good Mine Drill Bit, If It Is Inadvertently Dry, Does Not Use It In Accordance With Scientific Methods, It Will Also Be Scrapped In Advance, And It Will Not Be Able To Exert Rock Drill Bit Potential, And It Will Not Be Able To Reach a High Level.

Feature Advantage:

Tough And Wearable

1. With Excellent Rigidity And Toughness, Hardness Of The Head Portion Of The Steel Should Reach Hrc40 ~ 50, So As To Have Good Rigidity And Abrasion Resistance.
2. Have a High Yield Strength, Fatigue Strength, Impact Toughness And Fracture Toughness, Can Effectively Prevent Plastic Deformation And Brittle Fracture In The Drill Bit Body Pants, Sufficient To Ensure The Stability And Persistence Of The Drill Bit Geometry Work.
