Superior Hard Rock Drilling Power as Standard YT27 Pneumatic Rock Drill
 
Our Shenli YT27 rock drill adopts an 80mm diameter piston with 60mm stroke, reaching impact frequency above 36.7Hz. This high-output design outperforms ordinary pneumatic rock drill units on granite, basalt and other dense hard rock. The built-in high-torque rotating assembly prevents bit jamming during deep blast hole drilling, making it the preferred hard rock drill for long-hour underground mining rock drill operations in metal and coal mines.

Ergonomic Portable Jackleg Drill & Low-Fatigue Operation
 
Classified as a lightweight hand held rock drill, the 27kg body reduces operator burden during all-day work. Matched FT160A air leg delivers automatic feed propulsion, removing the need for manual body pressure. Concentrated integrated control handles simplify operation flow, while the detachable silencer cover cuts operational noise and freely adjusts exhaust direction—critical improvements for tunneling rock drill and confined underground mine environments. This portable rock drill design ensures stable grip even on slippery wet rock drill working surfaces.

All-in-One Air-Water Linkage Wet Rock Drill Mechanism
 
This YT27 air leg rock drill features full air-water interlock system, strictly enforcing mandatory wet drilling to comply with global mine safety standards. Compressed air simultaneously flushes rock cuttings from boreholes while powering percussion rotation, improving blast hole cleaning efficiency and reducing bit wear. The supporting FY250 oil feeder provides continuous automatic lubrication for internal moving parts, extending the service life of the entire rock drilling machine and lowering spare part replacement costs for mine operators.

Wide Cross-Industry Compatibility as Multi-Scenario Pusher Leg Rock Drill
 
As a versatile pusher leg drill and jackleg rock drill, the Shenli YT27 jack hammer mining drill adapts to all mainstream mining and construction verticals: coal mining rock drill for underground coal roadway development, gold mining rock drill and copper mining rock drill for metal ore extraction, quarry rock drill for open-pit stone blasting, plus railway tunnel, highway, water conservancy, metallurgy and national defense rock engineering. It drills 34–45mm diameter blast holes with maximum effective drilling depth of 5 meters, fully matching standard blasting construction parameters across continents.

Forged Wear-Resistant Construction & Low Failure Rate Mining Pneumatic Rock Drill
 
All key load-bearing components of this YT27 pneumatic rock drill are hot-forged high alloy steel with anti-corrosion and wear-resistant heat treatment. Sealing assemblies adopt imported rubber materials to resist water, dust and long-term air pressure erosion. Compared with casting-type rock drill equipment, our forged YT27 air leg rock drill cuts breakdown frequency by over 40%, ideal for remote mining sites with limited on-site maintenance support. We provide full sets of interchangeable spare parts for all rock drilling machine assemblies to support rapid field repair.
