Buying Guide: How to Choose Hacksaw Blades for Metal
Selecting the right hacksaw blade for metal cutting depends on several factors including material type, thickness, desired finish, and blade compatibility. Below are crucial purchase considerations to help narrow down the best option for your needs.
1. Tooth Per Inch (TPI) – Impact on Cutting
- Low TPI (14-18): Faster cutting suited for soft metals or thick sections where speed matters more than finish.
- Medium TPI (20-24): Balanced speed and finish; ideal for commonly encountered metals like steel pipes and bars.
- High TPI (32+): Finer teeth provide smoother, accurate cuts on thin or hardened metals but cut slower.
2. Blade Length and Width
Most standard hacksaw blades are 12 inches long and 1/2 inch wide. Longer blades cover more cutting length per stroke but require more space to operate. Junior hacksaws use shorter 6 to 10-inch blades for tighter spaces.
3. Material and Construction
Bi-metal blades combine high-speed steel teeth with a flexible spring steel backing, offering excellent durability, reduced breakage, and extended blade life. Carbon steel blades may be less durable and prone to faster wear.
4. Blade Thickness
Thicker blades tend to be more rigid and resist bending, suitable for straight cuts on thicker metal. Thinner blades are more flexible, ideal for curves or working in tight spaces.
5. Tooth Set and Shape
Wavy set teeth often provide smoother cuts by reducing material binding. Other tooth designs include raker and straight sets, each suited for different cutting tasks.
6. Compatibility with Hacksaw Frame
Confirm the blade length and width correspond with your hacksaw frame specifications to ensure proper fitting and tension.
7. Quantity and Price Considerations
Bulk packs offer good value for frequent users, while smaller packs suit occasional users. Consider your project volume before purchasing.
