Hand saw blades (commonly known as hacksaw blades) are integral components of manual cutting tools. Primarily used for cutting materials such as pipes, solid stock, wood, plastics, and machinable metals, they are a staple in manual cutting operations. The various material types include bi-metal, carbide grit, high-speed steel (HSS), carbon steel, and carbide grit rod-style blades. Among these, the bi-metal and HSS types offer superior flexibility; the carbide grit types are ideal for cutting hard materials such as glass and ceramic tiles; while the carbon steel types are characterized by their low cost and versatility.

Bi-Metal Hand Saw Blades: Used for cutting pipes, solid stock, wood, plastics, and all machinable metals. They offer superior heat and wear resistance, resulting in a longer service life. Their high flexibility helps prevent breakage during the cutting process.
Carbide Grit Hand Saw Blades: Used for cutting glass, hardened steel, stranded fiber optics, and ceramic tiles. Featuring exceptional heat and wear resistance, these blades are capable of cutting materials that other types of saw blades cannot handle.
High-Speed ​​Steel (HSS) Hand Saw Blades: Used for cutting pipes, solid stock, wood, plastics, and all machinable metals. The blade’s cutting edge possesses a higher hardness level than standard HSS blades. Highly flexible, they are well-suited for use with hacksaw frames that apply lower tension. The spine (back) of the blade remains unhardened to prevent breakage during cutting.
Carbon Steel Hand Saw Blades: Used for cutting pipes, solid stock, wood, plastics, and all machinable metals. These blades are characterized by their low cost and high versatility.
Carbide Grit Rod-Style Saw Blades: This specialized blade fits into standard hacksaw frames and is designed for cutting extremely hard materials, such as glass, ceramics, and hardened steel. The carbide cutting edge offers exceptional resistance to both heat and wear.
Bi-Metal Power Saw Blades: Designed for use with high-output power hacksaws.

Hand Saw Blade Specifications

The model numbers for hand hacksaw blades indicate the number of teeth per 25mm (approximately 1 inch) of blade length, typically categorized as follows:
(1) Fine-toothed: Corresponding tooth pitches are typically 0.8mm or 1.0mm; the tooth count per 25mm length ranges from 24 to 32 teeth. (2) Medium Serration: Corresponding pitch of 1.2–1.4 mm; 18–22 teeth per 25 mm length.
(3) Coarse Serration: Corresponding pitch of 1.8 mm; 14–16 teeth per 25 mm length.
