Description
The cutting blade in a band saw is a continuous loop that travels through the machine on pulleys. In a vertical band saw, the blade travels vertically through a slot in a table, and workpieces are hand-fed through the blade to make a cut.
A metal-cutting band saw uses blades that resemble a hack-saw. They are different from a wood-cutting saw.

Three-Tooth Rule
There should be a minimum of THREE TEETH of the saw blade engaged in a cut. If there are too few teeth in the cut, the advancing stock can catch too much of a blade tooth and shear it off. Teeth can be ejected into the user's face. In a less severe case the blade may be stalled.

|---|---|
- Wear closed-toe shoes.
- Do not wear loose clothing or jewelry when operating the machine. Long hair must be tied back or covered.
- Do not wear gloves. Gloves can be drawn into a cut by the moving blade.
- Keep fingers away from the line of cut. Use a push-stick or fixture
- Do not remove chips from the cutting area with bare hands. Use a chip brush.
- Always keep a secure, stable stance. Avoid over-reaching. Clean up oil spills immediately and avoid slipping. Keep the work area clear of trip hazards.
Machine
- Make sure all guards and covers are in place
- Lower the blade guard to within 3/8" of the highest point on the workpiece.
