Features and advantages of down-the-hole drill bits
Long drill life: made of alloy and diamond, its service life is long and higher than similar products;
High drilling efficiency: The drill teeth are wear-resistant, allowing the drill bit to always remain sharp, thus greatly increasing the tooth
feeding speed;
Stable drilling speed: the drill bit breaks the rock through impact and shearing;
Good diameter-keeping effect: The new diamond drill bit has strong wear resistance and good diameter-keeping performance, allowing the cutting teeth to be
efficiently utilized;
Wide range of use: Practice has proven that this drill bit is suitable for drilling in soft and medium-hard (rock formations
with drillability below level 9) such as carbonate rock, limestone, chalk rock, clay rock, siltstone, and sandstone. , compared
with ordinary drill bits, especially when drilling into 6-8 grade rock formations, the effect is particularly significant.
