技术指标
大直径扩孔器1.钢齿及航站
2. 6'-42的直径
3，严格的质量控制体系
在某些时候，可能有必要增加一个预钻孔的尺寸更大的直径或钻大直径孔中。 扩孔器的位专门为此目的而设计的。 位在广泛的风格定制生产，以满足现场需求。 自定义孔揭幕战是扩大孔的有效途径，故名洞开瓶器“。
该扩孔器的优势
- 直孔 - 钻一个小孔用导频比特，然后附加上述位上的开孔器的底部。 孔首战将遵循由小位钻洞的道路。
- 较大的孔与小钻机 - 通过钻级的孔，较大的孔可钻较小的钻机。 较小的孔需要更少的功耗。
- 更换刀具和降低成本 - 在大多数扩孔器的设计中，刀具可以很容易地更换。 替换的切割器的成本是成本的一小部分，以取代一个大三牙轮钻头。
- 大岩位成本 - 大口径牙轮钻头，不仅耗费了大量的，他们可能很难找到。 一个更经济的解决方案是使用使用更小的牙轮钻头段的孔揭幕战..
- 的flexability - 孔开罐器可以制造在几乎任何尺寸，并且可以被配置为钻透任何形成。

Specifications
Large Diameter Hole Opener1. Steel tooth & TCI available
2. 6'-42 in diameter
3. Strict Quality Control System
At some point it may be necessary to increase the size of a pre-drilled hole to a larger diameter or to drill large diameter holes. Hole opener bits are designed specifically for this purpose. Bits are custom manufactured in a wide range of styles to meet field requirements. A custom hole opener is an effective way of enlarging holes, hence the name Hole Opener'.
The Hole Opener Advantage
- Straighter Holes - By drilling a smaller hole with a pilot bit, then attaching that said bit onto the bottom of the the hole opener. The hole opener will follow the path of the hole drilled by the smaller bit.
- Larger Holes with Smaller Rigs - By drilling a hole in stages, larger holes can be drilled with smaller rigs. A smaller hole requires less power.
- Replacing Cutters and Cutting Cost - On most Hole Opener designs, the cutters can be easily replaced. The cost to replace a cutter is a fraction of the cost to replace a large tricone rock bit.
- Cost of Large Rock Bits - Larger diameter rock bits not only cost a lot, they can be difficult to find. A more economic solution is to use a hole opener that uses smaller tricone rock bit segments..
- Flexability - Hole Openers can be fabricated in just about any size, and can be configured to drill through any formation.
