What is a String Saw for Metal?
A string saw for metal is a compact cutting tool that uses a thin, flexible wire or cable looped between two handles. The saw cuts materials by a back-and-forth or continuous sawing motion. Unlike traditional saws with rigid blades, string saws leverage the tensioned wire’s abrasive surface—often stainless steel or diamond-coated—to slice through metal and other materials.
String saws for metal vary from emergency survival tools to advanced industrial wire saws. Their portability and ease of use make them popular in settings where power tools are impractical.
Types of String Saws for Metal
Stainless Steel Cable Saws
Commonly found on retail sites like www.amazon.ca, stainless steel cable saws are multi-stranded, flexible wires designed for cutting softer metals, wood, PVC, and bone. They typically measure around 20-24 inches and come with handles or loops for hand operation. Their affordability and portability make them ideal for camping, hiking, and survival kits.
Diamond Wire Saws
Used in industrial and precision settings, diamond wire saws feature a steel cable embedded with diamond particles. These saws, highlighted on www.diamondtoolstore.com and www.tedpella.com, deliver high cutting accuracy with minimal mechanical damage. They are employed in cutting hard metals, stone, concrete, and even delicate lab samples.
Wire String Saws for Survival
Featured on www.survival-gear.com, wire string saws are emergency tools designed to cut wood, bone, plastic, and soft metals like aircraft aluminum. Their multi-strand design allows cutting in any direction. However, users should apply steady, gentle pressure to avoid wire breakage due to overheating or excessive force.
Coping Saws with Diamond Wire
These are handheld frames fitted with diamond-coated wires, used for cutting metals and materials such as jade, marble, and glass. Popular among artisans and metalworkers (as described on quthought.com), these saws offer precision and control but require patience and skill.
Worm Drive Saws
While not traditional string saws, worm drive saws (referenced on www.skil.com) are powerful, lightweight tools with a unique gear system. Designed for heavy-duty metal and wood cutting, they are cordless and more suited for industrial or large-scale jobs rather than survival or handheld use.
How to Choose the Right String Saw for Metal
Selecting a string saw depends on your specific needs:
- For Emergency and Survival: Choose stainless steel cable saws or wire string saws for their portability and versatility.
- For Precision Metalworking: Opt for diamond wire saws or coping saws with diamond-coated wires.
- For Industrial or Large Jobs: Consider worm drive saws or professional diamond wire saw systems.
- Material Type: Evaluate if you need to cut soft metals like aluminum or harder metals such as steel.
- Portability: Smaller, hand-held options suit fieldwork; larger, powered saws are for workshops.
Applications of String Saws for Metal
Camping and Survival
String saws are essential in bug out bags, as noted on www.survival-gear.com and www.amazon.ca. Their ability to cut branches, soft metals, and plastic pipes makes them invaluable for shelter building, repairs, and emergency scenarios.
Metalworking and Crafting
Metalworkers use string saws, especially diamond wire and coping saws, to make precise cuts in sheets or small objects. According to quthought.com, these tools enhance control and reduce waste in crafting projects.
Industrial Cutting
Industries such as quarrying and demolition employ large-scale diamond wire saws (see www.diamondtoolstore.com). These saws cut through reinforced concrete, steel-encased materials, and stone with high efficiency and precision.
DIY and Home Repairs
Retailers like www.homedepot.com and www.amazon.ca offer cable saws suited for home tasks, from cutting PVC pipes to crafting wood and metal projects.
Using a String Saw for Metal: Tips and Best Practices
- Apply Steady Pressure: Avoid forcing the saw to prevent wire breakage and overheating (www.survival-gear.com).
- Keep the Wire Taut: Proper tension enhances cutting efficiency and safety.
- Lubricate When Possible: For tougher metals, use cutting oil or water to reduce friction.
- Wear Protective Gear: Gloves and eye protection are essential.
- Practice Cutting Technique: Start slow and maintain a consistent rhythm.
- Inspect Wire Before Use: Replace worn or frayed wires to avoid accidents.
Maintenance and Safety
String saws require minimal maintenance but must be kept clean and dry to prevent rust. After use, wipe the wire with an oily cloth and store in a protective case. Always inspect for kinks or broken strands. Follow safety guidelines to avoid injuries from sharp wires.
