The YT27 Air-Leg Rock Drill stands out as a cutting-edge tool in the realm of rock drilling machinery. Tailored for demanding environments such as railway, highway, and mining operations, this drill offers unparalleled efficiency and precision.
Known for its high-speed performance and robust design, the YT27 is the preferred choice for drilling horizontal and inclined blast holes in medium-hard to hard rock (f=8-18).
In short, the YT27 is a pneumatic pusher-leg rock drill used for highly efficient blast-hole drilling in tunneling, quarrying, and underground mining.
While both are industry standards, the YT27 is often favored for projects requiring a slightly heavier (27kg) and more stable drilling platform compared to the lighter YT28. The YT27 delivers higher impact frequency at the same pressure, making it excellent for rapid penetration in homogenous hard rock.

Q: Can the YT27 be used for vertical drilling?
A: The YT27 is primarily optimized for horizontal and inclined drilling using a pusher leg. For vertical upward drilling, a stoper rock drill or dedicated vertical rig is recommended.
Troubleshooting: What if my YT27 impact energy feels low?
A: 1. Check your FY250 line oiler; inadequate lubrication is the leading cause of power loss. 2. Ensure your air compressor is maintaining a stable 0.5-0.63 MPa at the tool inlet.
