Tip 1: Choosing the Right Chain and Chainsaw

Selecting the appropriate metal cutting chain and chainsaw is the foundation for success. Metal cutting chains are not universal; they come in various types designed for specific materials and chainsaw models.

Understanding Metal Cutting Chain Types

Diamond Chains: These chains feature diamond-impregnated segments brazed onto the chain body. They are primarily used for cutting concrete, stone, and masonry materials. They are particularly effective on materials like reinforced concrete where rebar is present. The diamond grit provides the cutting action, and these chains typically require water cooling to reduce friction and dust.
- Example: I used a diamond chain to cut through a concrete foundation wall during a building demolition. The chain sliced through the concrete and rebar with relative ease, significantly faster than using a jackhammer and concrete saw.
Carbide-Tipped Chains: These chains have tungsten carbide teeth brazed onto the chain links. They are designed for cutting abrasive materials like cast iron, ductile iron, asphalt, and even some sheet metals. Carbide is incredibly hard and resistant to wear, making these chains ideal for tough cutting tasks.
- Example: I utilized a carbide-tipped chain to cut through a large diameter ductile iron pipe during a water main repair. The chain quickly and cleanly cut through the pipe, minimizing downtime for the repair crew.
Specialized Chains: Some manufacturers offer chains designed for specific materials or applications. These might include chains for cutting tires, rubber, or even certain types of plastics.

Chainsaw Compatibility

Not all chainsaws are suitable for use with metal cutting chains. The chainsaw must have:

Sufficient Power: Metal cutting chains require more power than standard wood cutting chains. A chainsaw with a minimum engine displacement of 60cc is generally recommended for carbide-tipped chains, while diamond chains may require even larger and more powerful saws.
Proper Bar Length: The bar length must be compatible with the chain type and the material being cut. A longer bar provides more reach, but it also requires more power to drive the chain.
Adjustable Chain Oiler: Metal cutting chains require ample lubrication to reduce friction and heat. A chainsaw with an adjustable oiler allows you to increase the oil flow as needed. Diamond chains often require a dedicated water cooling system, which some chainsaws are equipped with.
Safety Features: Features like a chain brake, anti-vibration system, and throttle lock are essential for safe operation.

Practical Example: Selecting a Chainsaw and Chain for Cutting Ductile Iron

Suppose you need to cut through a 12-inch diameter ductile iron pipe. Here’s how to select the right chainsaw and chain:

Chainsaw Selection: Choose a chainsaw with at least a 60cc engine. A professional-grade saw like a Stihl MS 462 or Husqvarna 572XP would be ideal.
Chain Selection: Opt for a carbide-tipped chain specifically designed for cutting ductile iron. Ensure the chain length matches the chainsaw’s bar length.
Bar Length: Select a bar length that is long enough to cut through the pipe in a single pass. A 16-inch or 18-inch bar should be sufficient.
Oiler Adjustment: Before starting, adjust the chainsaw’s oiler to its maximum setting to provide ample lubrication to the chain.

Data and Insights

Power Requirements: Metal cutting chains typically require 20-30% more power than wood cutting chains.
Chain Speed: Optimal chain speed for metal cutting is typically lower than for wood cutting. Refer to the chain manufacturer’s recommendations.
Chain Life: The lifespan of a metal cutting chain depends on the material being cut and the operating conditions. Diamond chains can last for hundreds of cuts in concrete, while carbide-tipped chains may need to be sharpened or replaced more frequently.

Tip 2: Mastering the Cutting Technique

Cutting with a metal cutting chainsaw requires a different technique than cutting wood. The key is to let the chain do the work and avoid forcing it.

Smooth and Steady Pressure

Apply Gentle Pressure: Avoid applying excessive pressure to the chain. Let the chain’s cutting teeth or segments do the work. Forcing the chain can cause it to bind, overheat, or even break.
- Personal Experience: I once tried to rush a cut through a concrete slab and applied too much pressure to the diamond chain. The chain overheated, and some of the diamond segments delaminated from the chain body.
Maintain a Consistent Feed Rate: Keep the chain moving at a steady and controlled pace. Avoid jerky or erratic movements.
Listen to the Chainsaw: Pay attention to the sound of the chainsaw. If the engine starts to bog down, reduce the pressure and allow the chain to regain speed.

Cooling and Lubrication

Water Cooling (for Diamond Chains): Diamond chains require water cooling to prevent overheating and to flush away debris. Use a dedicated water cooling system or a garden hose with a nozzle to apply a steady stream of water to the chain.
- Example: When cutting concrete with a diamond chain, I always ensure a consistent flow of water to the cutting area. This not only cools the chain but also reduces the amount of airborne dust.
Oil Lubrication (for Carbide-Tipped Chains): Carbide-tipped chains require ample oil lubrication to reduce friction and heat. Use a high-quality bar and chain oil and adjust the chainsaw’s oiler to its maximum setting.
- Tip: I often add a small amount of extreme pressure (EP) gear oil to the bar and chain oil for added lubrication when cutting tough materials like ductile iron.

Avoiding Pinching

Use Wedges: When cutting thick materials, use wedges to prevent the cut from closing and pinching the chain.
- Scenario: Cutting a large diameter concrete pipe can cause the pipe to shift and pinch the chain. I use plastic wedges to keep the cut open and prevent the chain from binding.
Make Relief Cuts: For long cuts, make relief cuts to relieve stress in the material and prevent pinching.

Case Study: Cutting Rebar-Embedded Concrete

I was tasked with cutting several sections of rebar-embedded concrete columns during a bridge demolition. Here’s how I approached the task:

Chainsaw and Chain Selection: I used a Husqvarna K970 concrete saw with a diamond chain.
Water Cooling: I connected a garden hose to the saw’s water cooling system and adjusted the water flow to provide a steady stream to the chain.
Cutting Technique: I started by making a shallow cut around the perimeter of the column. Then, I gradually increased the depth of the cut, applying gentle pressure and maintaining a consistent feed rate.
Rebar Encounter: When the chain encountered rebar, I reduced the pressure slightly and allowed the chain to cut through the steel at its own pace.
Wedge Use: I used plastic wedges to keep the cut open and prevent the chain from pinching.
Safety Precautions: I wore a full-face shield, ear protection, and gloves to protect myself from flying debris and noise.

Data and Insights

Cutting Speed: Metal cutting chains typically cut slower than wood cutting chains. Expect to cut at a rate of 1-2 inches per minute in concrete and 2-4 inches per minute in ductile iron.
Chain Temperature: Monitor the chain temperature to prevent overheating. If the chain starts to smoke or discolor, stop cutting and allow it to cool down.
Water Consumption (Diamond Chains): Diamond chains can consume a significant amount of water. Expect to use 1-2 gallons of water per minute.

Tip 3: Prioritizing Safety Above All Else

Safety is paramount when working with any chainsaw, but metal cutting chains pose unique risks. The materials being cut can produce hazardous dust, sparks, and debris.

Personal Protective Equipment (PPE)

Eye Protection: Wear a full-face shield or safety glasses with side shields to protect your eyes from flying debris.
- Experience: I once had a piece of concrete ricochet off a rebar and strike my face shield. Without the shield, I would have suffered a serious eye injury.
Hearing Protection: Wear earplugs or earmuffs to protect your hearing from the loud noise of the chainsaw.
Respiratory Protection: Wear a respirator or dust mask to protect your lungs from hazardous dust. Concrete dust, in particular, contains silica, which can cause serious respiratory problems.
Gloves: Wear heavy-duty gloves to protect your hands from cuts, abrasions, and vibrations.
Protective Clothing: Wear long pants, a long-sleeved shirt, and steel-toed boots to protect your body from injury.
