Xi'an Heaven Abundant Mining Equipment CO.,LTD
Whether you are running a mining operation, managing a quarry, or drilling water wells, having reliable rock drilling tools is essential for maintaining productivity and controlling operational costs. At TY Drill Bits — Xi'an Heaven Abundant Mining Equipment CO.,LTD — we offer a comprehensive rock drilling tool wholesale catalog spanning thread button bits, DTH hammers and bits, taper button bits, drill rods, and related accessories. Every product is manufactured under ISO 9001 quality management, with 91%–100% of total sales going to international markets.
Thread button bits are the most widely used rock drilling tools in mining, quarrying, and tunneling. These bits feature tungsten carbide buttons press-fitted into a forged alloy steel body, with threaded connections that match standard drill rod profiles. At TY Drill Bits, we manufacture thread button bits across five major thread profiles — R25, R32, T38, T45, and T51 — covering hole diameters from 45 mm to 127 mm.
| Thread Size | Bit Diameter Range | Button Count | Best Application |
|---|---|---|---|
| R25 | 45 mm – 65 mm | 5 – 7 buttons | Small-scale mining, benching, light tunneling |
| R32 | 51 mm – 76 mm | 6 – 8 buttons | General mining, drifting, bolting |
| T38 | 64 mm – 89 mm | 7 – 9 buttons | Medium to hard rock drifting, production drilling |
| T45 | 76 mm – 102 mm | 8 – 12 buttons | Heavy-duty production, hard rock mining |
| T51 | 89 mm – 127 mm | 10 – 15 buttons | Large-diameter blast holes, quarry bench drilling |
We offer both standard face and retrac (retractable) designs. Retrac button bits feature a reverse taper skirt that assists in pulling the bit back through fractured or caving ground, reducing the risk of stuck drill strings. Our ｄｒｏｐ center face design improves flushing efficiency and bit stability in demanding conditions.
Down-the-Hole (DTH) drilling tools deliver consistent penetration rates regardless of hole depth because the hammer sits directly behind the bit at the bottom of the hole. This eliminates the energy loss that occurs through threaded rod joints in top hammer systems. TY Drill Bits supplies a complete DTH product line covering hammer compatibility with DHD, Mission, QL, SD, COP, and NUMA series.
| Hammer Model | Bit Diameter Range | Air Pressure | Best Application |
|---|---|---|---|
| DHD3.5 / Cir90 | 90 mm – 130 mm | 10 – 25 bar | Mining blast holes, borewell drilling |
| DHD340 / Cir110 | 110 mm – 140 mm | 10 – 25 bar | Water well drilling, quarry production |
| QL50 | 152 mm – 165 mm | 10 – 24 bar | Large-diameter boreholes, piling |
| BR2 | 75 mm – 90 mm | 8 – 18 bar | Small to medium mining and construction |
| Cir70 | 70 mm – 76 mm | Low pressure | Shallow water well, small-diameter applications |
Our DTH bits use cold-press interference fit technology to secure tungsten carbide buttons into precision-machined pockets. This manufacturing process achieves exceptional button retention — a critical factor for reducing downtime and maintaining cost efficiency in deep-hole drilling. We also supply DTH drill rods with API 2-3/8 Reg connections and friction-welded joints for maximum fatigue life.
Taper button bits are an economical choice for small-scale mining, construction anchoring, and benching operations. These bits connect to tapered drill rods via a conical friction fit — no threads required — making bit changes fast and simple. The standard taper angle is 7° or 11°, with bit diameters ranging from 32 mm to 45 mm.
| Taper Angle | Bit Diameter | Button Count | Typical Use |
|---|---|---|---|
| 7° | 32 mm – 38 mm | 5 – 7 buttons | Bolt anchoring, small benching |
| 11° | 36 mm – 45 mm | 7 – 9 buttons | General rock drilling, light mining |
| 12° | 34 mm – 40 mm | 7 buttons | Hand-held rock drill applications |
We also manufacture tapered drill rods in H22 and 7-degree hex configurations to match our taper button bits, ensuring a complete tooling system for pneumatic hand-held rock drills and jack hammers.
A drill bit is only as effective as the rod string that drives it. TY Drill Bits supplies extension drill rods, shank adapters, and coupling sleeves across the full R25 to T51 range, ensuring compatibility with major global drilling rig brands including Sandvik, Atlas Copco, and Furukawa.
Selecting the right rock drilling tools depends on five key factors: rock hardness, hole depth, hole diameter, drilling method, and available rig capacity. Making the correct choice at the procurement stage directly impacts your cost per drilled meter and overall project profitability.
| Rock Type | UCS (MPa) | Recommended Bit | Button Profile |
|---|---|---|---|
| Soft (limestone, shale) | < 80 | Top hammer or rotary | Ballistic / flat face |
| Medium (marble, dolomite) | 80 – 150 | Top hammer or DTH | Semi-ballistic mix |
| Hard (granite, basalt) | 150 – 250 | DTH preferred | Spherical buttons |
| Very Hard (quartzite) | > 250 | DTH essential | Spherical with heavy carbide |
| Factor | Top Hammer | DTH |
|---|---|---|
| Optimal hole depth | Up to 20 – 25 m | Unlimited (no energy loss with depth) |
| Hole diameter range | 32 – 127 mm | 90 – 1,000 mm |
| Hole straightness | Decreases with depth | Excellent at all depths |
| Capital cost | Lower (smaller compressor) | Higher (larger compressor required) |
| Best rock type | Medium to hard | Hard to very hard |
Rule of thumb: If your hole depth exceeds 15–20 meters or your hole diameter exceeds 115 mm, DTH drilling will almost always deliver a lower cost per drilled meter than top hammer in rock formations above 100 MPa UCS.
