When you need a high-performance concrete chainsaw solution, the Husqvarna K970III Chain (2-Bolt) stands out as a specialized option engineered for deep cuts, rugged durability, and precise cornering. In this guide, you’ll get complete technical data, real-world applications, installation tips, maintenance best practices, and buying advice — everything a contractor or serious user needs when evaluating this 2-bolt chain for Husqvarna K970 series power cutters.
What is the Husqvarna K970III Chain (2-Bolt)?
The Husqvarna K970III Chain (2-Bolt)—also sold as part number 967 66 05-01 in some listings—is a two-bolt diamond cutting chain designed specifically for the Husqvarna K970 series power cutters.
Key marketing descriptions highlight its ability for irregular deep cutting, making it ideal for openings, tight corners, and flush cuts in hard materials. The Husqvarna site states that with the 2-bolt K970 chain, you can cut up to 450 mm from one side and also create openings as small as 12 × 12 cm.
BladesDirect describes a maximum cutting depth of 390 mm (≈ 15.4 in) from one side and notes that the chain enables openings as small as 11 × 11 cm.
In applications, the K970III 2-bolt chain is suitable for cutting cast concrete, walls, floors, pavers, blocks, and structural adjustments where precision and depth are critical.
So in short: this is not a general-purpose wood-cutting chain, but a diamond chain engineered for aggressive concrete/stone work on the K970 cutter platform.
Technical Specifications & Performance
Here’s a breakdown of the most important specs you need to know:
| Parameter | Value / Range | Notes / References |
|---|---|---|

These features make it well suited for deep plunge cuts, corner cuts, and custom openings in concrete or masonry structures. The 2-bolt design gives mounting rigidity needed for high torque and vibration in heavy duty cutting.
Use Cases & Advantages
Why choose the K970III Chain (2-Bolt) over other diamond chains or cutting tools? Here's where it shines:
1. Irregular openings & corners
One of its standout features is the ability to make non-linear or boxed openings, such as square or rectangular cuts, without overcutting the corners. The chain’s cutting geometry and aggressive segment arrangement allow you to approach close to walls and corners. It supports openings down to ~11×11 cm (or 12×12 cm), making it useful for retrofits, plumbing or electrical penetrations, and renovation work.
2. Deep plunge cutting
With a reach up to 390 mm (and the Husqvarna site’s claim of 450 mm in some contexts), you can cut substantial depth from one side — useful for thick walls or concrete slabs.
3. Compatibility with K970 platform
Because this chain is purpose-matched to the Husqvarna K970 / K970III cutter and its 2-bolt mounting, it integrates with the cutter’s drive system, power output, and vibration/durability design. This means reduced slippage, more rigid mounting, and better reliability under high cutting loads.
4. Applications in walls, floors, pavers
This chain is useful across a broad set of jobs: cutting floors, walls, utility chases, pipe entry slots, removal of concrete segments, architectural adjustments, and block/paver cuts. It also works in wet cutting (with water supply) to cool, reduce dust, and extend chain life.
Installation & Mounting Considerations
To get optimal performance (and safety) out of the K970III Chain (2-Bolt), here are critical best practices:
1. Match to correct 2-bolt sprocket & drive layout
Ensure the cutter’s drive sprocket, shaft spline, and mounting holes match the chain’s layout. The “2-bolt” refers to how the chain interfaces with the cutter’s drive or guide interface—get proper alignment and torque spec.
2. Proper tensioning
Diamond chains require correct tension — too loose and the chain can slip or skip, too tight and segment stress or wear increases. Check tension during warm-up and operation cycles. Follow Husqvarna’s recommended adjustment intervals.
3. Use water / coolant for wet cutting
When cutting concrete or stone, always run with a wet cutting system (water feed) to:
-
Cool the cutting chain
-
Reduce dust and abrasion
-
Prolong chain and drive components life
Husqvarna’s cutter systems typically have water inlets and cooling infrastructure.
4. Segment rotation / indexing
If the diamonds or segments are directional or require indexing, ensure they are installed properly when mounting. For some chains, rotating segments or staging them can improve life and cut quality.
5. Sprocket maintenance / replacement
When installing a new chain, always check the sprocket condition. Worn sprockets reduce performance and accelerate chain wear. If the chain was changed many times without sprocket changes, consider replacing the sprocket along with the chain.
Maintenance, Safety & Performance Tips
To maximize life and performance of your K970III Chain (2-Bolt):
-
Flush out slurry: During or after use, flush the chain and cutter with clean water to remove residual slurry and abrasive particles.
-
Inspect segments regularly: Look for chipped, broken, or missing diamond segments. Replace chain if damage is present.
-
Proper storage: After use, clean and dry the chain; store with some light lubrication or rust preventative if conditions might cause corrosion.
-
Rotate chains (if possible): If you use multiple chains, rotate them to equalize wear across your fleet.
-
Use correct speed / feed rates: Pushing too slowly leads to glazing; pushing too fast overworks segments. Let the tool and chain do the work.
-
Safety gear: Always wear concrete-rated PPE: eye protection, dust masks (if dry cutting), hearing protection, gloves, protective boots, and explosion/vibration safe clothing.
FAQ
