When you are planning to buy a DTH bit for your next drilling project, you may wonder—why are the prices so different? Some bits seem cheap; others cost much more. Is it just about the brand? Not really. There are clear reasons why one bit costs more than another.
1. Bit Size Matters
The one thing that changes the price is bit size. Bigger bits use more raw materials like steel and carbide. They also take more time to produce and may need stronger machines to finish them.
If you’re drilling large blast holes or foundation piles, you’ll likely need a big DTH bit. These usually cost more, but they also save you time by making fewer passes. For smaller wells or sampling jobs, smaller bits can work and are cheaper.
So you should choose the size that fits the job—not too big, not too small. Otherwise, you spend more than needed, or the drilling goes slower.
2. Carbide Button Quality
Another important part of the DTH bit is the carbide button. These are the little tips on the face of the bit that actually hit and crush the rock. Carbide comes in different grades, and higher quality means better performance in hard rock.
High-quality carbide doesn’t chip or wear down fast. If you work with rough granite or tough conditions, you need stronger buttons. Lower-grade carbide may cost less but wears quickly, and you’ll need to change bits often.
Kaiqiu DTH Bits are made to handle strong impacts from the DTH Hammer, and the buttons are carefully selected for long-term use. That can make a difference if your project is in tough rock and deep holes.
3. Custom Design and Bit Face Shape
Some buyers ask for custom designs—for example, special flushing holes, different bit face shapes, or non-standard sizes. These features improve performance in specific drilling jobs. But custom also means more production steps, design time, and sometimes one-off tooling.
For example, a concave bit face can help center the drilling in broken rock. A flat face may be better for even surfaces. But custom means more cost, so it’s better to request them only if standard types are not enough.
If you’re not sure, you can always share your project condition with the supplier and let them guide you. Sometimes standard products do the job just fine.
4. Material and Heat Treatment
Bit body materials and how they are treated also affect the cost. At Kaiqiu, for example, the bit body is made with high-strength alloy steel, and the parts go through advanced heat treatment. This makes them stronger and helps the whole tool last longer—even under constant impact from the DTH hammer.
You might not see this from the outside, but when you use the bit, you’ll feel the difference. Cheap untreated material might work in the short term, but for deeper or hard rock drilling, it won’t survive long.
If you’re using a good DTH hammer like the ones from Kaiqiu, with a reliable piston and no inner cylinder, it makes sense to pair it with a matching quality bit. That way, both tools work together for better performance.
So next time you compare prices, look at size, carbide grade, design, and materials. Understanding these cost drivers can help you choose smarter—and drill better.
