Customizable items:
Cutting diameter customization: design the cutting diameter according to the customer's demand, such as φ950, φ1050, etc., which is mostly used in conjunction with casing construction.
Cylinder height customization: design the cylinder height according to the customer's demand, such as raising the height to 1500, 2000, to increase the single drilling volume and improve the construction efficiency.
Customization of the weight structure reinforcement: according to the customer's needs to strengthen the parameters of each part, such as wall thickness, bottom plate thickening, etc.
Customized square head size: according to the customer's square head of the drill pipe, we can customize the size of the square head of the drilling tool, usually 130x130, 150x150, 200x200, etc.
Customize the number of drill teeth: according to the customer's demand for drill teeth encryption arrangement.
