As a professional manufacturer specializing in rock drilling machinery, Shenli Pneumatic Machinery Co., Ltd. proudly presents the YT27 air leg rock drill, a versatile tool designed not only for stone carving but also for large-scale mining operations. This machine weighs 24kg with an overall length of 628mm, operating at 0.63MPa air pressure to deliver an impact energy of ≥65J and an impact frequency of ≥36Hz, enabling drilling diameters ranging from 34mm to 42mm and a maximum drilling depth of 5m . The operation of the YT27 is straightforward: paired with FY200A oiler and FT160A/B air leg, it supports wet drilling on medium to hard rocks (f=8-18); remove the air leg, and it can be mounted on a trolley for diverse working scenarios. A striking contrast exists between mines using conventional rock drills and those adopting the YT27. Traditional handheld drills require heavy manual labor, achieve slow drilling speeds, and are limited to shallow holes, while the YT27’s air-leg support reduces workers’ labor intensity significantly and boosts drilling efficiency by over 50% .
Choosing Shenli Pneumatic Machinery means opting for decades of expertise and uncompromising quality. Our factory adheres to strict production standards, with each YT27 undergoing rigorous testing to ensure durability and reliability—forged components enhance wear resistance, extending the machine’s service life by 30% compared to ordinary models . What truly sets us apart is our commitment to practical innovation: the YT27 features a flange control valve for precise air flow regulation, a powerful blowback function to clear drill holes effectively, and a high torque rotating mechanism that minimizes rock cracking . These design improvements translate to tangible efficiency gains: mines using the YT27 have reported a 55% reduction in drilling time per meter and a 40% decrease in energy consumption, as its air consumption (≤80L/s) is 15% lower than similar products on the market .
The advantages of the YT27 extend beyond efficiency. Its compact structure allows easy maneuvering in narrow mine tunnels and carving workshops, while the integrated air-water linkage system ensures clean drilling with reduced dust pollution, safeguarding workers’ health. The universality of its accessories further adds value—parts like the B22×108mm shank are readily available, lowering maintenance costs and downtime . For stone carvers, the YT27’s exceptional directional control ensures intricate drill work that preserves the integrity of precious stone materials. For miners, it delivers consistent performance even in harsh geological conditions, laying a solid foundation for safe and efficient blasting operations. Backed by our professional after-sales team providing timely technical support and spare parts supply, Shenli’s YT27 is more than a tool—it’s a long-term investment for businesses seeking to enhance productivity and competitiveness.
