Engineered for Performance: Key Features
The TACTI-CHAIN™ SLC45 is designed using Husqvarna’s decades of experience in diamond tool manufacturing. Every feature is engineered for precision, productivity, and long life, even in the most demanding environments.
1. Industrial-Grade Diamond Segments
Each link of the chain is embedded with synthetic diamonds, ensuring fast and efficient cutting through dense concrete and other mineral-based materials. These segments are laser-welded for superior strength, ensuring they remain firmly attached even during continuous heavy use.
2. Optimized Segment Bond
The medium-hard bond structure offers the perfect balance between cutting speed and wear resistance, making the SLC45 ideal for general-purpose use across a variety of materials— from soft concrete to lightly reinforced structures.
3. Low-Vibration, Smooth Cutting Action
Engineered for operator comfort, the SLC45 chain delivers smooth and stable cutting with minimal vibration. This not only improves accuracy but also reduces user fatigue during extended operation.
4. Wet Cutting Compatibility
Designed for wet cutting, the chain utilizes water to cool the diamond segments and flush away slurry, preventing overheating and extending chain lifespan.
5. Precision Depth Control
Husqvarna’s advanced chain geometry ensures consistent cutting depth, which enhances precision and minimizes the risk of overcutting or kickback.
6. Long Lifespan
Thanks to its superior diamond quality and optimized bond hardness, the SLC45 lasts significantly longer than conventional abrasive or carbide chains—reducing downtime and replacement costs.
