YT29S Air Leg Rock Drill: Premium Solution for Singapore Subterranean Infrastructure
As Singapore continues to pioneer deep underground space utilization and large-scale transportation infrastructure—such as the Cross Island Line (CRL), Deep Tunnel Sewerage System (DTSS Phase 2), and underground rock caverns—demand for reliable, high-impact rock drilling equipment has reached an unprecedented high. The YT29S Air Leg Rock Drill stands out as a heavy-duty, ultra-efficient pneumatic drilling machine designed specifically to tackle hard rock geology, including Singapore’s signature Bukit Timah Granite and Jurong Formation sandstones.
Manufactured under stringent ISO 9001 quality controls, the YT29S is engineered for high-speed blast-hole drilling, rock bolting, face trimming, and anchor-hole penetration in underground mining, tunneling, and civil engineering projects. Its reinforced air-leg thrust mechanism (compatible with FY200B oilers and standard air-legs) allows operators to achieve maximum linear drilling speeds with minimal vibration transfer and reduced pneumatic power loss.
Superior Hard Rock Penetration
Optimized stroke-to-impact frequency ratio delivers exceptional torque and percussive force for drilling rock hardness up to f=8–18 on the Protodyakonov scale.
Strong Water Flushing System
Features centralized water-air interaction control that suppresses hazardous dust particles, fully conforming to Singapore Workplace Safety and Health (WSH) regulations.
High Efficiency & Low Air Consumption
Engineered air valve design optimizes compressed air utilization (≤65 L/s at 0.5MPa), reducing energy costs for civil engineering contractors.
Singapore Industrial Landscape & Underground Construction Trends
Singapore’s urban density requires moving major infrastructure subterranean. This unique civil engineering landscape presents distinct challenges: strict noise emission limits set by the National Environment Agency (NEA), limited site footprints, and extremely dense rock structures beneath urban zones.
1. Underground Utilities & MRT Tunnelling
In narrow tunnel shafts where heavy automated jumbo drill rigs cannot easily maneuver, handheld air-leg rock drills like the YT29S provide indispensable operational flexibility. Contractors working on MRT station caverns, pipe-jacking launch shafts, and drainage tunnels rely on YT29S drills for precision face drilling, secondary rock splitting, and ground support bolt installation.
2. Rock Cavern Excavation & Underground Storage
Projects like the Jurong Rock Caverns demonstrate Singapore’s push toward subterranean storage for energy, water, and industrial facilities. The YT29S rock drill excels in continuous rock face excavation where durability, quick maintenance turnaround, and standardized wearing parts are vital to maintaining 24/7 excavation timelines.
3. Coastal Reclamation & Slope Stabilization
For slope anchoring along cut-and-cover highway corridors such as the North-South Corridor (NSC) and marine reclamation retaining walls, YT29S drills deliver fast horizontal and inclined drilling capabilities when attached to versatile air legs.

Frequently Asked Questions (FAQ) - Singapore Procurement
Common questions from engineering contractors and machinery distributors in Singapore regarding YT29S rock drills.
Why is the YT29S Air Leg Rock Drill preferred for underground tunnelling in Singapore?
The YT29S provides an ideal combination of strong percussive energy, high flushing efficiency, and ergonomic weight (26.5kg). In Singapore’s dense urban underground sites (such as MRT caverns and cable tunnels), space limitations prevent large rig entry. The YT29S allows operators to quickly execute blast holes and rock bolt anchor holes through tough Bukit Timah Granite while suppressing dust via its heavy-duty water flushing system.
What size air compressor is required to run the YT29S rock drill effectively?
The YT29S requires a working air pressure of 0.4 to 0.63 MPa with an air consumption of ≤65 L/s. We recommend pairing it with compressed air units such as the 3.0/5 Mining Piston Air Compressor or LUY120-14 high-pressure mobile air compressors to ensure stable pressure delivery during continuous drilling operations.
How does SHENLI handle spare parts delivery and post-sales support for Singapore clients?
We maintain full inventory of genuine wearing parts—including pistons, valve assemblies, ratchet rings, water needles, and FY200B oiler seals. Orders bound for Singapore can be shipped quickly via direct sea freight to Jurong/Tuas Port or expedited air freight, ensuring minimal downtime for active construction projects.
Do your rock drills and pneumatic picks meet Singapore health and safety standards?
Yes, all SHENLI pneumatic rock drills and air picks carry official CE compliance certification and are manufactured in ISO 9001:2015 certified facilities. Their integrated wet-flushing system effective suppresses respirable crystalline silica dust, aiding compliance with Singapore Workplace Safety and Health (WSH) guidelines.
