Dth hammer drill bits. Dth hammer button bits are designed to make operations easier by drilling further, whatever the conditions. Let's take a look at the types of down-the-hole drill bits and their respective characteristics.
Advantages of new diamond dive drilling
The longer life of the drill: the alloy material, with longer using life which better than the similar products;
High Drilling efficiency: the drill buttons is wear-resistant, so that the drill can always keep sharp, thus greatly improving the speed of thedrilling.
The drilling speed is stable: the bit is scraped and cut to break the rock.
Good Performance: the Dminingwell dth hammer button bit has strong wear resistance, good diameter protection and can make the cutting teethbe used efficiently.The use of a wide range: the practice proves that the bit is suitablefor carbonate rock, limestone,chalk, clay rock, siltstone, sandstone and other soft and hard (9 grade drillability of rock, hard rock drilling), compared with normal bit, especially drilling in 6-8 grade rock the efect is particularly significant.
The down-the-hole bit is mainly used in geological exploration, coal mine, water conservancy and hydropower, highway, railroad and bridge construction and building construction.
Drill Bit Characteristics
Flat Face
This flat face down-the-hole bit is suitable for drilling very hard rock formations and corrosive wall formations at high air pressures. When the bits is drilling the faster the drilling speed, the less wear of the drill body.
Concave Face
This concave face is suitable for all rock formations, especially in medium-hard and homogeneous rock formations, the effect is good. The blast hole deviation is small, and the slag discharge effect is good.
Convex Face
This Convex face is suitable for low-to medium-pressure drilling of soft-medium hard rock formations, and the drill block is not easy to corrode.The characteristics of this design are the low load of the sidebutton, the wear is not badly and the drilling speed is fast.
Double Gauge Face
This double-sided button face is suitable for drilling very hard rock formations at hiah air pressures. When the dth hammer drill bit is drilling, drilling speed is fast, the bit body wear will also be less.
Drop Center
When using low-medium pressure to drillsoft-medium hard and fractured rock formations, in order to obtain fast rock driing speed and less blasthole slope, this face shape DTH drill bit is usually used.
Summarize
Dth hammer drill bits are used with DTH hammers to drill holes in a variety of formations. DTH drill bits are available in almost every size, but we stock the most common sizes and configurations for immediate delivery.
