Blade Selection
When selecting the proper blade for the job, these important facts must be considered.
- The size of the workpiece determines which blade should be used.
- A minimum of three teeth should be engaged in the material at all times, to eliminate snagging, catching and tooth breakage.
| TEETH PER INCH | MATERIAL SIZE (THICKNESS) |
| 14 TPI |
5/8" and over |
| 18 TPI |
1/4" to 5/8" |
| 24 TPI |
1/8" to 1/4" |
| 32 TPI |
5/16" and under |
- Also, soft or gummy materials can be best cut by using a coarser tooth. This choice will prevent chips from jamming and clogging the gullets, reducing the efficiency of the blade.
Installation and Technique
- 1. Install blade with teeth pointing away from operator.
- 2. Apply sufficient tension to assure blade rigidity for straight cuts.
- 3. Pressure should be applied on the forward, or cutting stroke.
- 4. Long, steady strokes should be used, not exceeding 50 per minute.
- 5. Saw as close to the vise as possible to eliminate vibration.
- 6. Do not start cut on a corner, or sharp edge.
