"WSC" is a casing tube with excellent strength and threading. It can be safely used as an essential threaded casing for replacing perforated PVC pipes, galvanized pipes, screens, and more. The threaded joint section uses special steel, and to ensure thread strength, we custom order our original size from the pipe manufacturing company. Additionally, it undergoes heat treatment to provide appropriate hardness and ductility. 【Features】 ■ The thread shape has been revised to withstand the powerful impact energy of air hammers and pulling forces, dispersing stress. ■ The remaining thickness of the threaded joint has been considered, and the inner and outer diameters have been machined. ■ With a focus on processing precision, skilled technicians cut high-precision threads and assess them by touch. *For more details, please refer to the PDF document or feel free to contact us.

Our company offers the essential reaming bit for the double-tube method, the 'ADMS W Type'. The blade attachment has been improved from the traditional structure that relied on pin holes, eliminating the risk of pins falling out. Additionally, improvements to the pilot bit section have enhanced the upward movement of slime (cuttings) and the weight balance. 【Features】 ■ Structure that is resistant to hole bending ■ Locking mechanism to prevent diameter reduction during drilling ■ Reinforced blade increases the reaming section by 60% (compared to our conventional model), allowing for smooth bit rotation ■ Changed the structure of blade retention from pin hole type (our conventional model) to eliminate pin detachment ■ Easy disassembly, inspection, and replacement of parts *For more details, please download the PDF or feel free to contact us.
