Most underground mining and rock excavation projects still rely on the classic drill-and-blast workflow, a proven method valued for its stability and cost efficiency. The YT27 air-leg rock drill fits seamlessly into these conventional working routines, delivering steady, trustworthy drilling performance to keep daily construction running smoothly. As an experienced professional manufacturer specializing in rock drilling machinery, we developed the YT27 pneumatic rock drill to adapt to modern harsh mining working conditions while inheriting the stable and practical advantages of traditional drilling equipment.
Lightweight and highly efficient, the YT27 is purpose-built for wet drilling on medium-hard to hard rock with a firmness coefficient of f=8 to 18. It supports blast hole diameters ranging from 34mm to 45mm, with a maximum effective drilling depth of 5 meters, fully meeting conventional mining and tunneling drilling requirements. Matched perfectly with FY250 lubricators and FT160A / FT160B air legs, the drill can stably complete horizontal, vertical and inclined hole drilling on various construction sites. Featuring a user-friendly and simple structural design, the equipment only requires basic connection of air and water pipelines and simple adjustment of the air leg height before operation. It greatly shortens operator training cycles and effectively improves overall on-site construction efficiency.
Compared with outdated traditional rock drills that suffer from low impact power, frequent faults and excessive air consumption, the YT27 achieves comprehensive performance upgrades. Equipped with a high-performance impact structure, it delivers a stable impact energy of over 75.5 joules and an impact frequency above 36.7 Hz, boosting actual drilling speed by 30% while greatly reducing compressed air consumption and lowering operational energy costs. Old-fashioned drilling tools often fail to clean drill holes thoroughly, easily causing drill bit jamming and construction delays. In contrast, the YT27 features powerful flushing capacity that keeps drill holes clean throughout the working process, eliminating stuck tool risks and ensuring continuous and stable drilling progress.
With an integrated compact and rigid structure (overall dimension: 668×248×202mm, net weight: only 27kg), the YT27 minimizes daily wear and tear with extremely low maintenance requirements. It solves the core pain points of traditional equipment such as frequent part replacement and frequent downtime maintenance, helping users save long-term operation and maintenance costs.
Tailored for harsh underground mining environments, the YT27 maintains stable operation where ordinary drilling tools struggle. Its exclusive air-water linkage system ensures smooth startup and normal operation even in humid, dusty mine sites, avoiding common faults such as startup failure and tool jamming that plague low-end drilling equipment. The equipment outputs strong and stable torque, which not only accelerates rock breaking and drilling speed, but also maintains consistent working performance when penetrating hard rock layers like granite and quartz. It completely improves the problem of uneven drilling progress of traditional drills in complex geological conditions.
In actual on-site use, the YT27’s ergonomic structural design effectively reduces vibration and operational fatigue during long-hour continuous work, helping operators maintain stable working efficiency throughout the shift. All core components are forged from high-hardness, wear-resistant alloy materials, undergoing strict heat treatment and precision processing. The whole machine features strong impact resistance and structural stability, adapting to long-term high-vibration and high-load mining operation scenarios. Field application data verifies that the YT27 effectively reduces equipment failure frequency, extends maintenance intervals and cuts the overall total cost of ownership compared with old-generation drilling tools.
The core advantage of the YT27 lies in its perfect balance of practical innovation and mature traditional technology. It adopts optimized structural designs such as flange control valves to realize precise air pressure adjustment and stable power output. At the same time, it retains the simple and reliable mechanical structure that mining workers are familiar with, abandoning the overly complicated intelligent design that brings high failure rates and high learning costs. The equipment requires no professional technical training or expensive software maintenance, achieving stable and efficient drilling performance for a long time.
Boasting excellent compatibility and versatility, the YT27 can directly replace outdated handheld rock drills and perfectly adapt to traditional drill-and-blast mining workflows. After removing the supporting air leg, it can also be installed on drilling jumbos for large-scale centralized drilling operations, fully meeting the diverse construction needs of small manual operation and large mechanical matching operation.
For mining enterprises that insist on adopting mature and stable drill-and-blast processes, the YT27 is not merely a replacement drilling tool, but a practical and cost-effective equipment upgrade solution. It effectively improves drilling output and construction quality, reduces comprehensive operation costs, and maximizes the service life and operational efficiency of existing mining workflows. Backed by strict factory quality control standards and complete global after-sales service support, every YT27 rock drill delivers reliable quality and stable performance, providing solid equipment guarantee for the sustainable and efficient operation of global mining and tunneling projects.
