A jigsaw is designed for intricate cutting tasks, particularly curved and detailed cuts. It is a reciprocating saw, meaning the blade moves back and forth, making it versatile in handling different materials.
Specifications:
- Blade Length: 5 inches
- Blade Width: 1/20″ to 1/4″
- Teeth Per Inch (TPI): 8-10 for wood, special blades for other materials
- Power Output: 400 to 600 watts (average for consumer models)
- Cutting Speed: Up to 3,500 strokes per minute
Applications:
- Curved and intricate cuts in wood, plywood, and MDF.
- Cutting sheet metal, plastics, and ceramic tiles with appropriate blades.
- Bevel cuts up to 45°.
| Cutting Type | Application |
|---|---|
| Curved Cuts | For cutting irregular shapes and patterns in wood, metal, and tile. |
| Straight Cuts | Uses a wider blade for accuracy in straight lines. |
| Plunge Cuts | Cutting holes or starting from the middle of materials rather than the edge. |
| Bevel Cuts | Achieving angled cuts, typically up to 45°, depending on model. |
2. Circular Saw
A circular saw uses a round blade to cut through various materials, including wood, plastic, and metals. Its ability to make straight cuts quickly makes it a staple in both professional and DIY setups.
Specifications:

- Metal Cutting: Using abrasive or diamond-tipped blades.
- Masonry Work: Cutting through concrete, stone, and tile.
| Type of Circular Saw | Application |
|---|---|
| Corded Circular Saw | Suitable for continuous heavy-duty work in construction. |
| Cordless Circular Saw | Portable but typically less powerful, ideal for light tasks. |
| Track Saw | For precision cuts using a guide track. |
| Worm Drive Circular Saw | More torque for tough materials like metals and concrete. |
3. Chainsaw
A chainsaw is typically used for cutting through wood, logs, and trees. It features a rotating chain with sharp teeth, making it ideal for heavy-duty tasks such as felling trees or chopping firewood.

- Blade Size: 10 to 12 inches
- Cutting Capacity: Up to 12 inches wide
- Power Output: 1,500 to 1,800 watts
- Bevel Range: 0° to 45° (varies by model)
Applications:
- Framing, trimming, and carpentry.
- Making precise miter cuts for woodworking and construction.
- Cutting boards for siding or molding.
| Angle Settings | Application |
|---|---|
| 0° (Straight Cut) | Standard crosscutting of boards. |
| 15°, 30°, 45° | Pre-set angles for fast and efficient cuts in frames and moldings. |
5. Compound Miter Saw

A compound miter saw allows for both miter and bevel cuts, making it more versatile than the basic miter saw. Its pivoting head allows angled cuts in both horizontal and vertical planes.
Specifications:
- Blade Size: 10 to 12 inches
- Bevel Angle: Up to 45° in both directions
- Power Output: 1,500 to 1,800 watts
Applications:
- Cutting angles and bevels in wood for furniture and trim work.
- Producing compound angles for more complex projects, like crown molding.
6. Band Saw (Stationary & Portable)
A band saw consists of a continuous loop blade, ideal for cutting irregular shapes and ripping wood. It is available in stationary and portable versions.
Specifications:
- Blade Width: 1/8 to 1 inch
- Teeth Per Inch (TPI): 6 to 14, depending on the material
- Cutting Depth: Up to 12 inches for stationary models
Applications:
- Precision cuts in woodworking, metal cutting, and meat processing.
- Resawing lumber into thinner pieces.
| Band Saw Type | Application |
|---|---|
| Stationary Band Saw | For large, precise cuts, particularly in furniture making. |
| Portable Band Saw | Lightweight and mobile, ideal for cutting metal pipes or beams. |
7. Table Saw
A table saw is perfect for making long, precise cuts in large sheets of material. The saw blade is mounted on a table for stability during continuous cuts.
Specifications:
- Blade Diameter: 10 to 12 inches
- Cutting Depth: Up to 3.5 inches at 90°
- Power Output: 1.5 to 2.5 HP
Applications:
- Cutting large sheets of wood and plywood.
