What Is a DHD3.5 DTH Hammer?
A DHD3.5 DTH Hammer is a down-the-hole percussion drilling tool used together with compatible DHD3.5/IR3.5 DTH bits. During drilling, compressed air drives the piston inside the hammer, and the impact energy is transferred directly to the drill bit at the bottom of the hole. This makes the hammer suitable for drilling through rock formations where stable impact, hole cleaning, and drilling efficiency are important.
Compared with only discussing the price of a hammer, professional buyers usually need to check whether the hammer, bit shank, hole diameter, air compressor capacity, drilling rig, and rock formation are properly matched. A correctly matched 3.5 inch DTH hammer and bits system can help reduce abnormal wear, unstable impact, poor flushing, and unnecessary downtime on site.
Who Is This DHD3.5/IR3.5 DTH Hammer For?
This product is suitable for drilling teams and distributors who need a compact DTH hammer for small-to-medium diameter rock drilling. It is commonly considered by:
- Water well drilling contractors working with 90–110mm hole sizes
- Geotechnical and construction drilling companies
- Quarry and mining contractors drilling in hard or medium-hard formations
- Drilling tool distributors looking for a stable IR3.5 DTH hammer supplier
- Importers who need factory-direct supply with technical matching support
Where Can the DHD3.5 DTH Hammer Be Used?
The DHD3.5/IR3.5 hammer is suitable for projects where drilling diameter, machine capacity, air pressure, and formation hardness match the 3.5 inch hammer range. Typical application scenarios include:
- Water well drilling: for small-diameter rock drilling where stable air flushing and reliable impact are required.
- Construction drilling: for foundation-related drilling, anchoring support, and site investigation work.
- Quarry drilling: for rock drilling operations where tool life and drilling consistency affect daily productivity.
- Geotechnical drilling: for drilling projects that require reliable penetration in mixed or hard ground conditions.

Why Buyers Choose LEANOMS DHD3.5/IR3.5 DTH Hammer and Bits
For B2B buyers, a DTH hammer is not only a single tool purchase. It affects drilling speed, bit consumption, compressor use, site downtime, and replacement cost. LEANOMS focuses on practical tool matching and stable export supply, helping buyers reduce the risk of buying a hammer that does not fit their actual drilling conditions.
Reliable Structure for Hard Rock Drilling
The DHD3.5/IR3.5 DTH hammer is designed for impact drilling in rock formations. The hammer body, piston, internal air path, top sub, and bit shank matching all affect drilling stability. LEANOMS pays attention to material selection, machining accuracy, and assembly control to help maintain consistent performance during normal drilling operations.
Practical Hole Range: 90–110mm
This hammer is recommended for 90–110mm hole drilling. Before ordering, buyers should check whether the planned hole diameter, casing requirement, bit size, rig capacity, and compressor output are suitable. Oversized or mismatched bit selection may reduce drilling efficiency and increase wear risk.
API 2 3/8" Reg Connection
The API 2 3/8" Reg connection makes the hammer suitable for many drilling rod configurations used in small DTH drilling systems. However, thread compatibility should always be checked before shipment, especially when the buyer is replacing tools from another brand or mixing existing drill rods with new hammers.
Stable Air Consumption Reference
According to the technical parameters of this model, the air consumption is approximately 6.5 m³/min at 14 bar and 13.7 m³/min at 24 bar. Buyers should compare these values with their compressor capacity before purchase. If the compressor output is insufficient, the hammer may not work efficiently even if the size appears correct.
Compatible DTH Bits Available
LEANOMS can supply matching DHD3.5/IR3.5 DTH bits according to the required diameter and drilling formation. Common options can include different face designs, button shapes, carbide configurations, and flushing hole arrangements. For abrasive, fractured, or very hard formations, it is better to confirm rock conditions before finalizing the bit design.
Key Technical and Commercial Advantages
- Factory-direct supply: fewer middle layers help buyers control procurement cost.
- Matched hammer and bit solution: buyers can purchase compatible hammers and bits together to reduce mismatch risk.
- Project-based recommendation: tool selection can be discussed based on hole diameter, rock formation, air pressure, and compressor capacity.
- Export packing support: reinforced packing can be arranged to reduce damage risk during long-distance transportation.
- OEM and wholesale support: suitable for drilling contractors, distributors, and bulk order buyers.
Common Buyer Concerns Before Ordering
1. Will the hammer match my existing drill rods?
Please check the connection thread. This model uses API 2 3/8" Reg. If your existing drill rods use another thread type, an adapter or a different configuration may be required.
2. Is my compressor powerful enough?
The working pressure range is 7–25 bar. Air consumption is approximately 6.5 m³/min at 14 bar and 13.7 m³/min at 24 bar. Compressor pressure and air volume should both be checked before confirming the order.
3. What bit diameter should I choose?
The recommended hole range is 90–110mm. The final bit diameter should depend on the required hole size, casing plan, drilling depth, and rock formation.
4. Can I use this hammer in very abrasive rock?
It can be used in suitable hard rock conditions, but bit design becomes more important in abrasive formations. Buyers should provide rock information or old bit photos so that the button shape, face design, and carbide layout can be selected more accurately.
5. How can I reduce shipping and replacement risk?
For export orders, LEANOMS can arrange reinforced packing, product photos or videos before shipment, and clearer model marking to help buyers reduce wrong-delivery, damage, and receiving-check risks.
How to Evaluate Before Ordering
To select the right DHD3.5 hammer for water well drilling or other rock drilling projects, buyers are advised to confirm the following information before quotation:
- Required hole diameter
- Drilling depth and project type
- Rock formation, such as limestone, granite, basalt, sandstone, or mixed ground
- Current hammer model or old tool photos
- Air compressor pressure and air volume
- Drill rod thread type
- Expected order quantity and delivery schedule
This information helps avoid incorrect matching and allows us to recommend a more practical hammer and bit combination for your job site.
