Description
Bi-Metal hacksaw blade:
Bi-metal hacksaw blades are a superior option for cutting through metal compared to traditional carbon steel blades. Here’s a breakdown of their key characteristics:
Construction:
- Two-metal combination: They combine two metals for improved performance.
- High-Speed Steel (HSS) Teeth: The teeth are made from high-speed steel, which is very hard and wear-resistant. This allows the blade to stay sharp for longer and tackle tough metals effectively.
- Flexible Steel Back: The back of the blade is typically made from a more flexible steel. This provides several benefits:
- Shatter Resistance: The blade is less likely to snap during use due to the increased flexibility.
- Improved Control: The flexibility allows the blade to conform slightly to the material being cut, offering better control.
- Tensioning: The flexible back can be adequately tensioned in the hacksaw frame for optimal cutting performance.
Benefits:
- Longer lifespan: HSS teeth stay sharp significantly longer than carbon steel teeth, resulting in more cuts per blade.
- Faster cutting: The hardness of HSS teeth allows for faster cutting compared to carbon steel blades.
- Versatility: Bi-metal blades can handle a wider range of metals compared to carbon steel blades, including mild steel, stainless steel, and even some harder alloys.
- Smoother cuts: The combination of sharp teeth and a slight flex in the blade can result in smoother cuts compared to stiff carbon steel blades.
Applications:
Bi-metal hacksaw blades are ideal for various metal cutting tasks, including:
- Cutting pipes and conduit
- Sheet metal fabrication
- Bolts, rods, and other metal stock
- General purpose metalworking applications
Choosing a Bi-Metal Hacksaw Blade:
When selecting a bi-metal hacksaw blade, consider these factors:
- Teeth Per Inch (TPI): Higher TPI blades (18-32 TPI) provide finer cuts for smoother finishes, while lower TPI blades (10-14 TPI) cut faster but leave rougher edges. Choose the TPI based on your desired cutting style and material thickness.
- Blade Length: Standard lengths are 10 inches and 12 inches. Ensure the blade fits your hacksaw frame.
- Blade Width: Common widths are 1/2 inch and 3/4 inch. Wider blades offer more stability for thicker materials.
Bi-Metal hacksaw blade specifications:
- Quantity: Some sources mention "THT541036" as a 10-piece bi-metal hacksaw blade set.
- Size: The blades might be 12 inches long based on common hacksaw blade sizes, but confirmation is needed.
- Teeth Per Inch (TPI): Without further information, the TPI (teeth per inch) is unknown. TPI determines the cutting style (fine or fast).
