When you're driving roadway tunnels in medium-hard rock and every meter of advance feels like a battle, the usual struggle is keeping the drill going without constant jams or slowdowns — that's where this pneumatic rock drill fits in, basically built for crews who need consistent penetration through granite or limestone without babysitting the tool.
It weighs 27kg and runs at about 0.63 MPa working air presure, delivering 75.5 joules of impact energy per blow at a percussive frequency of 36.7 Hz or higher, which means it chews through rock at a decent clip — borehole diameters form 34 to 45mm, max depth of 5 meters, and air consumption stays under 80 L/s, so you're not starving your compressor.
The air-water linkage is actually handy for keeping dust down and flushing cuttings out of the hole, and the quick-return air leg saves you from wrestling teh thing back out after each rod change — most buyers go with the R22×108mm bit head size, but you can run button bits within that range.
What you get when ordering is drill itself with a one-year warranty and 24/7 techncial support, plus CE and ISO 9001:2000 certifcation — lead time is usually 20 days or so, but we usually have stock, so confirm with us before assuming.
Our MOQ is 10 units for the YT27, but we can be flexible for first-time orders or trial runs—just reach out to us.
Standard lead time is 15-20 working days after order confirmation. If you need it faster, we can expedite for an additional fee.
Yes, it is CE and ISO 9001:2000 certified. We can provide the documentation upon request.
The YT27 drills up to 5 meters deep with a borehole diameter of 34-45mm. With 75.5J impact energy and rotary percussion, it works well in medium-hard rock.
Each drill is packed in a plywood case with foam padding to prevent damage. Store it in a dry, ventilated area between -20°C and 40°C to keep it in good condition.
