Reciprocating Saw Blades

Reciprocating saws can cut through a wide range of materials if the right type blade is used

Reciprocating Saw Blades - Buying Guide

Reciprocating saws can churn through metal, masonry, wood, plaster, fiberglass, stucco, composites, drywall and more. But the key to a successful cut is using the right type of blade for the material you are cutting.

This buying guide highlights the teeth, dimensions, composition and uses of reciprocating saw blades.

Teeth

The number of teeth per inch (TPI), along with gullet size, width and depth of the space between the teeth determines the material the blade can cut

  • Blades with a low TPI deliver faster cuts with rougher edges and are ideal for cutting wood.
  • Blades with a high TPI deliver smooth, slow cuts and are ideal for cutting metal.
  • The number of TPI ranges from 3 – 24.
  • Try to have at least 3 teeth come in contact with the material at all times to reduce snagging.

Dimensions

There are three dimensions to keep in mind for blades: length, width and thickness

  • Reciprocating saw blades range from 3 – 12-inches long.
  • Keep in mind, the longer the blade, the deeper the cut.
  • Wider blades reduce bending and wobbling.
  • Heavy duty blades tend to be 7/8-inches wide and 0.062-inches thick.
  • Blades with 0.035-inches thick provide adequate strength for standard cuts.
  • Blades with 0.05-inches thick provide enhanced stability.
  • Short blades with tapered backs are best suited for plunge-cutting jobs.

Composition and Uses

Reciprocating saw blades are usually made of carbon steel, high-speed steel, bi-metal or carbide grit

  • Carbon steel blades are flexible to allow bending without breaking and are great for cutting wood or plastic.
  • High-speed steel blades have durable teeth, but are more prone to breakage, and last up to 5-times longer than high-carbon steel.
  • Bi-metal blades are combine high-speed steel teeth for longevity and heat resistance, with a carbon-steel body for flexibility and break-resistance, and last up to 10-times longer than high-carbon steel.
  • Carbide-grit blades are used for materials such as fiberglass, ceramic tile and cement board.
