3115306510 , 3115 3065 10 DRILL COLLAR ATLAS COPCO

(OEM-standard dust/impact collar for Atlas Copco rock drills — supplied worldwide by 3GEN Export in 5 working days)

---

Overview

The 3115306510, 3115 3065 10 DRILL COLLAR ATLAS COPCO is the protective interface that seals the front of the drifter, keeps abrasive cuttings out of the rotation assembly, and cushions the oscillation that occurs around the shank area during percussion. Purpose-built from a high-resilience elastomer compound, this drill collar maintains its geometry under repeated compression, providing a consistent barrier against dust, water, and back-splash while the bit and rod are rotating at speed.

Supplied by 3GEN Export, the part is engineered to OEM dimensional tolerances so it slides onto your guide/bushing seat and mates perfectly with the chuck and front head. The result is a stable, self-centering seal that improves drilling efficiency, extends service intervals, and protects expensive components in the harshest mining and tunneling environments.

Why the drill collar matters

During each blow of the drifter piston, the shank adapter and rod move axially while the rotation system drives torque into the bit. That combined motion generates a turbulent flow of fines and water at the front head. If those abrasives work their way into the guide and rotation chuck, they act like grinding paste—accelerating wear, overheating bearings, and deforming sealing lands.

The ATLAS COPCO 3115306510 solves that problem in three ways:

1. Sealing – its lip and bell profile form a dynamic dust/water barrier around the rod, preventing ingress into the front bushing and chuck.

2. Damping – the compound absorbs lateral vibration and micro-impacts around the shank area, reducing noise and protecting mating surfaces.

3. Centering – the collar’s tapered inner throat keeps the rod aligned in the housing, helping the bit start straight and minimizing hole deviation.

Those three functions combine to keep your drifter clean, cool, and efficient—especially when drilling in abrasive formations or when flushing water carries large volumes of fines.

3115306510 Materials & construction

• High-resilience elastomer compound
  A premium rubber formulation engineered for rock-drill duty: high tear strength, outstanding rebound, and excellent resistance to cut growth. The compound remains flexible in cold temperatures yet resists softening at elevated temperatures created by friction and poor flushing.

• Reinforced lip geometry
  The sealing lip is radiused to prevent nicks during rod changes. The shoulder transitions into a thicker energy-absorbing “bell” that dampens oscillations from the rod.

• Molded accuracy
  Each collar is precision-molded with controlled wall thickness to maintain clamping pressure and shape over thousands of cycles. The inner throat is finished to a smooth surface to avoid rod scoring.

• Hydrocarbon & water resistance
  Compatible with drilling water, foams, and misting oils commonly used in Atlas Copco rigs. The compound resists swelling in contact with lubricants and maintains sealing pressure across long shifts.

---

Performance characteristics

• Reliable dust/water exclusion – protects the front guide, rotation chuck, and seal packs from abrasive ingress.

• Impact and vibration damping – reduces peak stresses transmitted to the front head, slowing wear on housings and fasteners.

• Thermal stability – retains stiffness and lip force in temperature swings from cold starts to sustained heavy drilling.

• Shape memory – the bell profile springs back after compression, maintaining a constant seal despite axial rod motion.

• Quick replacement – flexible enough to install without special tools; tough enough to survive repeated rod changes.

3115306510 Compatibility

The collar geometry and throat size match the Atlas Copco COP-series drifters most commonly used on Boomer, Simba, and ROC/FlexiROC rigs. Typical fitment includes (non-exhaustive):

• COP 1238 / 1638 / 1838 / 1840 / 1850

• COP 2238 / 2240 / 2560 / 3060

• ROC D7 / D9 / L6 / L8 surface drill rigs

• Boomer underground jumbos (HD variants)

• Simba long-hole rigs where the front head share the same collar seat

If you’re cross-referencing from site stock lists, the molded profile in the photos and the nominal throat/OD dimensions match the 3115-3065-10 seat. For other Atlas Copco seat sizes, 3GEN Export supplies the full collar range.

Installation guide (best practice)

1. Clean the seat
   Remove the old collar, wipe the front guide and shoulder with a lint-free rag, and flush away fines. Any grit trapped under the seal will abrade the seat.

2. Inspect the rod & guide
   Check the rod for burrs and the guide lip for sharp edges. Stone any high spots lightly; nicks cut seals.

3. Lubricate lightly
   Apply a thin film of water-based assembly lube (or clean drilling water) to the inner throat—just enough to slide; excessive oil can attract dust.

4. Seat squarely
   Slide the collar squarely over the rod and press home against the guide shoulder. Ensure the bell sits flat with no waviness.

5. Run-in check
   After a few holes, stop and verify that the collar remains seated and the lip is not folded. Re-seat if necessary.

Service tip: Many operators replace the drill collar at every major front-end service (along with front bushing/guide and shank adapter). The small cost of a fresh collar protects the expensive parts behind it.

Maintenance & service intervals

• Daily: Wipe the collar lip clean during rod changes; check for cuts or chunks missing.

• Weekly: Inspect seating shoulder for dust packing; remove packed fines that can create a leak path.

• Replace if:

  • the lip has deep nicks or flattened areas,

  • the bell has permanent set (does not spring back), or

  • dust is visible past the seal into the guide area.

Regular attention to the drill collar prevents contamination of bearings and seal lands—extending the life of the rotation group and reducing oil consumption due to abrasive wear.

---

Field-proven benefits

• Cleaner front head — less abrasive slurry gets into the chuck and guide, keeping torque stable and bearings cool.

• Longer component life — rotation bushings, front seals, and shank adapters last longer due to reduced grit load.

• Better hole quality — the centering effect keeps the rod running true, reducing hole wandering and bit chatter.

• Fewer stoppages — fast, tool-less replacement; operators can swap a collar during normal rod handling.

• Lower total cost — a low-cost consumable that protects the most expensive parts of the drifter.

3115306510 Applications

• Hard-rock mining & tunneling: high dust loads, continuous percussion cycles, and abrasive formations.

• Quarrying: dry drilling and intermittent flushing where dust sealing is critical.

• Construction & ground support: bolt holes, fore-poling, and production drilling in mixed ground.

Wherever an Atlas Copco COP drifter works, the 3115306510 DRILL COLLAR 3115 3065 10  maintains front-end cleanliness and stability.

Frequently asked technical questions

Q: Can the 3115306510 collar be used in both water-flush and air-mist drilling?
A: Yes. The compound is compatible with water, foams, and typical misting oils. It maintains sealing force across a wide temperature range.

Q: How often should the collar be replaced?
A: Many sites change collars every front-end service or when visual damage appears. In dusty, dry drilling the interval is shorter; in well-flushed conditions it may last considerably longer.

Q: Will a harder compound last longer?
A: Not always. Excessive hardness reduces lip compliance and sealing effectiveness, allowing dust ingress that accelerates wear behind the collar. The supplied hardness balances life and sealing.

Q: Is there a left-/right-hand version?
A: No. The collar is symmetrical and can be installed in either orientation as long as it sits squarely on the shoulder.
