3. Drill rods are made from quality heat treated materials which ensure superior strength, wear resistance and toughness in the most demanding applications
4. Rods and casing are manufactured under stringent industry standards, and are field tested under a variety of conditions.
5. All rods are designed to be compatible with other rods manufactured to the standard DCDMA
W casings are made in DCDMA standards ,the most popular sizesand are AW, BW, NW, NWA, HW, and PW standards applied in geotechnial drilling.
Raw materials:
We choose the best steel tubes in the market to manufacture our rods and pipes. Instant check will be conducted after the raw material is delivered to our plant so that it canmake sure the compositions and specifications meet the inspection form the suppliers.
Heat treatment control:
Heat treatment will greatly make sure the material strength and the thread wear life of the rods and casings. We conduct either tru-wall or both ends heat treatment to the tube body.
Thread opening process:
Precision of threads will impact the use effects and serve time of drill rod and casings.
CNC latches and form cutter are used in thread opening process to minimize error .
Additional thread treatment:
Surface of the threads will be cleaned to remove burr adhered after threads are opened.
At last , the tread surface will be phosphated to improve surface conditions.

Hole Openers can be quoted with new/unused surplus or used Steel Tooth or TCI Cutters Hole Openers.
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.
Operational Considerations
Drilling Weight - The choice of drilling weight is determined based on the recommendations of the bit manufacturer and the number of cutters on the hole opener.
Number of Cutters - The number of cutters placed on a hole opener is governed by the following facts:
1.Maximum number which will fit around the perimeter.
2.The greater the number of cutters, the less the weight, which therefore reduces the penetration rate.
3.In softer formations, less weight is needed to penetrate.
4.The greater the number of cutters, the smoother the tool will run.
5.The greater the number of cutters, the greater the cost.
6.The greater the number of cutters, the longer the cutters will last
Rotary Speed - Maximum speed is determined by the manufacturer's recommendation and the calculation to account for the linear distance the cutter is moving per revolution.
Hole Cleaning - A frequently over looked point of hole opener operation is hole cleaning. The volume of cuttings to remove from a hole increase by a squared factor with an increase in hole diameter.
Applications:
â?¦ PDC drill bit is mainly used to drill Oil well, gas well, water well, etc.
â?¦ We design and produce specifie PDC bit with good performance for each soft, medium and hard formation.
â?¦ Clay stone/lignite/siltstone/sands: We design 3-5 blades with low density cutter placement,large slot. Low cost,high speed .
â?¦ Mudstone: We have experience to design suitalbe blades shape and cutter direction to get high drill speed and stalbe drill.
â?¦ Gravel/limestone/shale/clay stone/tuff: Round crown and reasonable cutter direction. Drill smoothly in good speed.

In today's fiercely competitive mechanical processing field, whether deep hole processing tasks can be completed efficiently and accurately is directly related to the product quality and market competitiveness of the enterprise. I am very honored to introduce to you the high-performance deep hole drilling machine developed by our company, which can definitely become a capable assistant on your company's production line, helping you to break through the processing bottleneck and move to a higher level of development.
This deep hole drilling machine combines cutting-edge technology and exquisite craftsmanship. First of all, it is unique in drilling accuracy. We use a high-precision guide system and advanced CNC technology to ensure that the hole diameter tolerance is controlled within a very small range. The hole wall drilled by our deep hole drill is smooth and has excellent straightness, which effectively reduces the subsequent processing steps, saves you a lot of time and cost, and makes your products fit tightly during assembly with better performance.
Speaking of efficiency, it is one of its highlights. Equipped with a high-power, high-speed dedicated spindle, combined with a unique chip removal technology, the drilling speed is greatly improved. The efficient chip removal system can also ensure that the processing process is continuous and uninterrupted, avoiding problems such as tool wear and hole wall scratches caused by chip accumulation, further ensuring the stability and efficiency of processing, allowing you to complete more orders in a shorter time and quickly seize the market opportunity.
