Highlights
Key Advantages
- Drops straight into COP1838 and multiple Atlas Copco drifters without modifications.
- Tough alloy steel that handles shock loads without cracking – less unplanned downtime underground.
- Replaces 3115 2950 00, works with 3115194500 setups. We ship from stock so you’re not waiting weeks.
- Surface-hardened contact faces resist mushrooming, which means fewer teardowns over the rig’s shift life.
- If your old front head is galling threads or leaking flush air, this one solves it on the next PM cycle.
Use Cases
Applications
- Underground production drilling with COP 1838 drifters on jumbos.
- Open-pit blast hole rigs where dust and moisture eat cheap heads fast.
- Tunnel face drilling and rock bolting – keeps cycle times tight.
- Dimension stone quarries that need straight holes, not bent steel.
- Large-scale mine development, from declines to ore passes.

FAQ
FAQ
Will this front head work on my COP1838+ or COP1840?
It fits the standard COP1838. The + model uses 3115545800; HD versions like the 1840 need 3115504200. Physically different mounting flange and porting. Send us a photo of your data plate and we’ll confirm the right one in minutes.
How do I know if this is the correct replacement before ordering?
Look at the part number stamped on your old head, or check the rig’s maintenance log. Still not sure? Tell us your drill model and serial – we match it to factory records, not guesswork.
What’s your actual lead time? Can you expedite?
We keep physical stock. Typical dispatch is 2–5 working days. For breakdowns, we tag orders “rush” and ship same day if booked before 11am (CST). Real-time stock – just ask.
Are these genuine Atlas Copco parts or aftermarket?
We supply both OEM-sourced units and premium aftermarket equivalents. Each comes with full batch traceability, QA reports, and a standard warranty. We’ll tell you the source before you pay.
Installation – any special tools or torque specs?
Standard drifter service tools will do it. Head bolts need accurate torque and a clean mating surface – skip that and you’ll crack the flange. We include the torque pattern and specs with every order. Have your drill tech handle it.
