Gravel, pebbles, and boulder layers are effective for drilling in collapsed ground!
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.
