What are the parts of a saw?

Back: the edge opposite the toothed edge. Fleam: The angle of the faces of the teeth relative to a line perpendicular to the face of the saw. Gullet: The valley between the points of the teeth. Heel: The end closest to the handle.

What is the base of the circular saw called?

shoe
The base of the circular saw, called the shoe, rests on top of the material being cut. For a regular straight cut, the shoe and the blade are at a 90-degree angle.

What are the notches on a circular saw?

Every saw has notches or marks on the front of the shoe to indicate where the blade is going to cut, but they’re not very easy to follow. They get covered with sawdust or the whole shoe gets bent out of whack, which throws off the guide.

What three kinds of teeth do circular saw blades have?

Circular Blade Teeth 101
- FLAT TOP GRIND TEETH (FTG) These teeth plow through the wood.
- ALTERNATE TOP BEVEL TEETH (ATB) These Teeth cut like knives, scoring the wood to minimize tear-out.
- HIGH-ANGLE ALTERNATE TOP BEVEL (Hi-ATB)
- TRIPLE-CHIP GRIND (TCG)
How many teeth does a circular saw blade have?

Framing blades have 24 teeth and are effective for jobs like rough carpentry where speed is more important than getting a clean cut. Plywood blades have 100 or more fine teeth designed to create a finish with minimal splintering. Thin-kerf blades have a narrow profile for faster, easier cutting and less material waste.

What are the parts of a table saw called?

All table saws share the same basic anatomy: They all have a base, a table and extension wings, rails and a rip fence, a motor, trunnions, gearing to raise and tilt the blade, and an arbor and arbor assembly.
