Refers to the cemented carbide cutting tools in the drilling process is the wear and tear, and the contact area remains the same bit.self-sharpening carbide drill bits are commonly used in a small section of the acicular (phi = 2 mm h = 10 ~ 15 mm) cemented carbide cutting tools and fusible metal (Cu30 Fe70 %, %) pressure sintering block,needle cutting with the tire body wrapped up; Or with a thin sheet cutting (1 mm x 5 mm x 20 mm) in order to support to enhance the bending capacity of the steel. Along with the drilling bit of metal or supported metal prior to cutting tool wear off, the cutting small section constantly exposed to the broken rock.self-sharpening carbide drill bits are suitable for hard and abrasive is strong, fracture of Ⅵ ~ Ⅷ grade drillability of rocks. Diagram is the circumscription of acicular alloy have ll ~ 13, the needle diameter 2 mm. Panel board embedded in the bit body straight face, above 5 ~ 6 mm needle carbide drill.
 

Application recommend

 
Using range: the practice proves that the bit is suitable for carbonate rock, limestone, chalk and clay rock, siltstone, sandstone, etc in the soft and hard (hereinafter of rock drillability grade 9) formation drilling, compared with the average bit, especially 6-8 level of rock drilling, is especially significant effect;
For fast drilling rate and long service life, thus, fewer drilling, drilling cost is reduced greatly, the superior price.
