产品描述：

拖bitsalso命名叶片位，一个TC插入在叶片上。

它们areusually设计用于软地层如砂，粘土，或一些软岩的使用。

他们usesinclude钻探水井，采矿，地热，环境和explorationdrilling 。

Wheneverpossible ，它们应该被用于钻导向孔，因为他们产生cuttingsthat是最简单的登录。

通常dragbits是三翼，而有时人们需要四个翅膀五个翅膀。

其他specialdesign可根据您的要求。

PDC阻力位

特征： highwear阻力和耐冲击韧性，长钻孔使用寿命， drillingefficiency可以大幅的软介质andmedium -硬地层渗透促进，关于劳动强度可以降低。

Product Description:

Drag bitsalso named blade bits, with a TC inserts on the blades.

They areusually designed for use in soft formations such as sand, clay, or some softrock.

Their usesinclude drilling water wells, mining, geothermal, environmental and explorationdrilling.

Wheneverpossible, they should be used to drill pilot holes, for they produce cuttingsthat are easiest to log.

Usually dragbits are three wings, while sometime people need four wings or five wings.

Other specialdesign is available upon your request.

PDC drag bit

Characteristics: highwear resistance and impact-resistant toughness, long drilling life, drillingefficiency can be promoted sharply in penetration of soft medium andmedium-hard formation, laber intensity can be reduced.
