- Hacksaw blades are designed to cut metal or plastic. Hacksaws consist of a blade held in a steel frame with relatively high tension to hold the blade rigidly straight.
- High-tension models (with tension to 50,000 p.s.i.) are also available.
- 10 Inch & 12 Inch Blades come in coarse-, medium (18 tpi), fine (24 teeth per inch and very fine-toothed (32 tpi). Regular or standard blades are used for general-purpose cutting; high-speed or bi-metal blades for cutting hard, extra-tough steel.
- Most frames can be adjusted to hold various blade lengths. Some have both horizontal and vertical positions for blades. Others provide blade storage.
- A close-quarter (or utility) hacksaw holds and positions a hacksaw blade so it can be used effectively in narrow spaces and slots.
- Replacement blades include rod saw blades capable of cutting through most hard materials—spring and stainless steel, chain, brick, glass and tile.
- When using hacksaws, make sure the blade is secured with the teeth pointing forward and that the frame is aligned properly.
- When cutting with a hacksaw, use the full length of blade in each cutting stroke.
