MACH DTH Button Bits
DTH Drill Bits are produced from premium quality nickel-alloy steel for increased durability and wear characteristics. Specific heat treatment standards and special "stress relief" processes ensure consistent performance.
DTH hammer bits are designed for maximum performance and hole cleaning ability and high penetration rate.
Our bits are interchangeable with Atlas Copco's COP32 34 44 54 64 84, Ingersoll-Rand 's DHD3.5,DHD3.5HD, DHD 340A , DHD350R, DHD 360, DHD380 QL40, QL50 , QL60, QL80.NUMA100, NUMA120, MISSION60, etc.
Our DTH hammer and bits are compatible with CIR, DHD, QL, SD, Mission, etc. Series of Atlas and Sandvik etc. They are with high efficiency, low failure rate and long service life. Even for all kinds of high hardness, high abrasive rocks and other harsh conditions, our drilling tools can also realize efficient and economical drilling.
Down The Hole(DTH) Drill Button Bit for Drilling Mining Hammer.
Compared with the oversea brands, our advantages are bellowing:
1. Our products can match over 95% against the original products
2. Price are competitive against the famous brands and best quality against the small factory
3. Using higher grade carbides for longer life;
4. Minimizes hole erosion in fragile formations
5. Drills faster through soft formations with less blockages
6. Drills straighter through consolidated and unconsolidated formations

DIFFERENT FACES STYLES:
Flat face: This is an universal design, especially for hard and abrasive rock formation. So typically, flat face with hemi-spherical buttons design is the most popular choice.
Convex face: A classic design for soft to medium hard rock formation which is not so abrasive. This design have very excellent penetration rate but poor in hole deviation if rocks are hard.
Concave face: Medium hard to hard rock formations which is less abrasive and fractured. Especially for deep hole drilling, excellent control over hole deviation.
Double Gauge face: A special design for hard or very hard rock conditions, double gauge row buttons provide very excellent ware-resistance and very longer life time. It is usually used for some bigger diameter DTH bits. Besides, we are manufacturing the DTH bits with various shanks so they can be compatible with different DTH hammers
