We've been running these hammers across a few different sites now, and they handle the high-presure side better than most—usually around 8-25 bar, but you'll want to match the model to your compressor output for best results. The BR2 and BR3 are pretty much the go-to for most medium-depth work, while the WD30R is a bit more niche for harder rock.
The valveless air distribution is a nice touch because of that it basically cuts down on moving parts that can fail, and the hardening on teh alloy steel means they don't wear as fast as some cheaper options out there. You're looking at about 30-60 r/min for rotary speed, but the impact rate varies by model so check the spec sheet for your specific bit series—it's compatiible with COP, DHD, SD, QL, and MISSION, so you won't need to swap everything out.
For mining and tunnel boring, these hold up well, though I'd say for very abrasive conditions you might want to swap in a harder grade of steel or just plan for more frequent inspection. A concrete detail: threads on the API/REG connection are cut tighter than some competitors, which helps avoid that annoying cross-threading under load.
3 months warranty is standerd for us, and we usually have stock on the common sizes (give or take a week for custom runs), but confirm lead time if you're ordering more than 50 units or so. The CE and ISO certifications are in place, so compliance shouldn't be an issue—just make sure your air supply stays below 25 bar to avoid over-stressing the piston.
The main differences are in impact rate and size—each model is designed for specific drill rig compatibility. BR2 and BR3 are standard series, while WD30R is a heavy-duty variant for tougher rock formations. Check your rig's specs to pick the right model.
Yes, we can include a mill test certificate for the alloy steel and a CE or ISO9001:2000 compliance certificate upon request. Just let your sales rep know when placing the order.
Our MOQ is typically 10 pieces per model variant, but we can sometimes do smaller trial orders for first-time buyers. Contact us to discuss your specific needs.
Keep them in a dry, clean area with stable temperature, ideally off the ground on pallets. Apply a light rust-preventive oil if storing for more than a few weeks—this is standard for hardened alloy steel bits.
Yes, our bits are designed to fit COP, DHD, SD, QL, and MISSION series hammers. As long as your hammer uses API/REG threads and the working pressure is within 8-25 bar, you're good to go.
