| Wood-Cutting Blade | 5–10 TPI | Softwood, hardwood, plywood, dimensional lumber | Framing, rough cuts, pruning, demolition work | Fast material removal and deep cutting capacity | Coarse teeth cut quickly but leave a rougher surface; use a longer blade when cutting large stock. |
| Wood with Nails Blade | 6–10 TPI | Wood containing nails, screws, and other embedded fasteners | Pallet dismantling, wall openings, roof and floor renovation | Greater resistance to occasional contact with metal fasteners | Use moderate pressure and allow the blade to cut rather than forcing it through hidden metal. |
| Metal-Cutting Blade | 14–24 TPI | Steel tubing, sheet metal, threaded rod, conduit, aluminum | Pipe cutting, fabrication, automotive repair, installation work | Fine teeth provide controlled cutting and a cleaner edge in thin sections | Select a higher TPI for thin material and maintain steady speed to reduce tooth stripping. |
| Thick-Metal Blade | 8–14 TPI | Thick steel plate, cast iron, heavy structural sections | Structural demolition, heavy equipment repair, steel fabrication | More robust teeth and gullets for demanding cuts | Cutting speed is usually slower than with wood blades; use suitable cutting lubricant where appropriate. |
| Bi-Metal Blade | Variable, commonly 8/12–14/18 TPI | Wood, metal, plastic, and mixed construction materials | General renovation, maintenance, demolition, multi-material cutting | Combines a flexible blade body with wear-resistant teeth | A versatile choice, but dedicated blades normally deliver better results in specialized materials. |
| Demolition Blade | 5–14 TPI | Mixed wood, nails, screws, drywall, plastic, and light metal | Building removal, renovation, pallet dismantling, emergency access | Designed for impact, variable materials, and rough cutting conditions | Prioritizes durability and speed over finish quality; inspect the work area for hidden utilities. |
| Pruning Blade | 3–8 TPI | Green wood, branches, logs, and tree limbs | Tree trimming, landscaping, storm cleanup | Large gullets clear wet chips and fibrous material efficiently | Keep the blade clear of soil and avoid forcing the cut, which can bend or damage the blade. |
| Carbide-Grit Blade | Grit-edged; no conventional TPI | Cast iron, ceramic tile, cement board, fiberglass, abrasive composites | Tile removal, plumbing renovation, cement-board cutting | Handles abrasive and brittle materials that can damage standard teeth | Produces dust and may cut more slowly; wear suitable eye, respiratory, and hearing protection. |
| Carbide-Tipped Blade | Variable, commonly 6–14 TPI | Stainless steel, hardened fasteners, cast iron, thick metal | Heavy-duty metal cutting and difficult demolition tasks | Long tooth life and improved performance on hard, abrasive metals | Typically costs more than standard blades; avoid twisting the blade during a cut. |
| Drywall and Plaster Blade | 6–10 TPI | Gypsum board, plasterboard, and light construction panels | Electrical openings, plumbing access, interior remodeling | Quick access cuts with a flexible blade profile | Use controlled strokes to limit damage behind the panel and check for wiring or pipes first. |
| Plastic and PVC Blade | 10–18 TPI | PVC pipe, ABS pipe, acrylic, and other rigid plastics | Plumbing installation, drainage repair, enclosure modification | Finer teeth help reduce chipping and tearing | Avoid excessive speed and pressure because heat can soften or melt some plastics. |
