What Is Dth Technology Dth Drill Bit Button Bits Rock Drilling
Description:
The New Carbide Button Can Work Under Great Pressure, But As The Carbide Button Wear, The Appearance Of The Plane Creates a Horizontal Or Shearing Load At The Bottom.
An Increase In The Rotational Speed Does Not Increase The Crossing Rate, But Will Increase The Wear Frequency, Especially In Abrasive Formations. Under Abrasive Conditions,
Applications:
Recommended To Control The Frequency Of Wear According To The Depth To Be Drilled In Order To Determine The Frequency Of The Necessary Regrind. Although Different Manufacturers, We Recommend That The Plane Width Of The Teeth Does Not Exceed 1/4 Of The Diameter Of The Bottom.
Feature Advantage:
The Flattening Of The Surface Carbide Button Generally Indicates That The Flow Energy Of The Hammer Is Lacking, Or That The Button Moment Is Insufficient. Inspect The Drill Bit To See If There Are Tiny Hot Streaks At The Bottom, Or Similar Snakeskin Patterns, Or Surface Cracks Due To Overheating Of The Carbide Button .
