What to Consider When Choosing the Best Reciprocating Blades

A number of technical factors impact both performance and durability when choosing any saw blade, including the blade’s material, teeth per inch, length and shape, and thickness.


  • High carbon steel (HCS) is probably the most common material for Sawzall blades. It’s relatively inexpensive, flexible, and moderately durable. These blades can cut wood, plastic, and many composites. Don’t confuse it with high speed steel (HSS), which is harder, stays sharp longer, is rather brittle, and seldom used by itself for reciprocating saw blades.
  • Bi-metal blades combine the best of HCS and HSS. Although a little more expensive, they’re very durable with improved edge retention. They cut faster for a longer time.
  • Carbide (actually tungsten carbide) is an extremely hard compound utilized to further improve cutting performance. Carbide-tipped blades, generally used to cut metal, can last 20 times longer than bi-metal blades. Carbide-grit blades have no teeth, but the blade edge is coated with coarse grit. They’re particularly good at cutting fiber cement, concrete, and fiberglass.
  • Diamond-coated reciprocating saw blades offer the best cutting edge. Similar in construction to carbide-grit blades, they can saw through extremely hard materials like cast iron with relative ease. They also are the most expensive type of reciprocating saw blade.

Teeth Per Inch (TPI) 

The number of teeth per inch (TPI) on a reciprocating saw blade says a lot about its capabilities. Low TPI generally means a coarse finish to the cut, but a high TPI means it’s smoother. However, also consider the material that’s being sawed.

For instance, green wood has a soft, fibrous structure, so if using a saw with high TPI, the teeth may jam up with pulp and won’t cut. Gaps between the teeth (called gullets) help clear the waste caused by the soft fibers. As a result, a pruning blade might have as low as 4 or 5 TPI.

On the other end of the scale, hard metals are best cut with blades with many small teeth set close together, or high TPI. Reciprocating saw blades for steel can be from 14 to 24 TPI.

The best reciprocating saws for any given task are those that combine the right blade material with the correct TPI. While the manufacturer’s guidance is usually fairly accurate, sometimes it’s a question of trial and error. For beginners, purchasing a pack of reciprocating saw blades in assorted sizes is a good idea, because it’s a low-cost way to try a variety of TPI blades.

Length and Shape

Most reciprocating saw blades are between 6 and 12 inches long. Shorter blades are convenient when working in confined spaces, while longer blades are useful when sawing wide boards or tree limbs.

When choosing blade length, also consider safety. A reciprocating saw performs a back-and-forth sawing action. If the blade is too short, it can jump out of the cut on the pull stroke and crash into the workpiece as it goes forward again. Given a reciprocating saw’s speed, this can not only break the blade but also cause a nasty operator injury. Experts generally recommend using a blade that’s 3 inches longer than the thickness of the workpiece.

Wood-cutting reciprocating saw blades are usually slender and tapered toward the tip. Blades for harder materials, on the other hand, particularly those with carbide grit or diamond coated, are deeper, with a back that runs parallel to the teeth to provide more support and reduce deflection.


Thicker blades usually have relatively high TPI. These stiffer blades are more suitable for heavy-duty work such as demolition or auto body work. Additionally, they’re often more durable and vibrate less, which can reduce hand fatigue.

However, a thick blade also means a wider “kerf,” the width of the cut, and thus how much material the blade can remove. For a fine cut, use a thinner blade.

Best Wood

Luckyway 10-Piece 6 Inch Reciprocating Saw Blades Set

See It

These Luckyway reciprocating saw blades can cut softwood, plywood, laminates, MDF, and plastic pipe. Made of high carbon steel, they’re 6 inches long with 6 TPI. While it’s not the strongest material, it’s an economical choice.

At 0.05-inch thick, the blades leave a thin kerf. They also can perform light pruning, though the length limits the branch size. A 9-inch alternative is available. If cutting hardwoods, a higher TPI blade probably would be more useful.

Best Multipurpose

Milwaukee The Ax 9-Inch Reciprocating Saw Blades

See It

These hard-wearing bi-metal blades from Milwaukee are often called demolition blades. Designed for jobs in which old nails or screws might be hidden in wood or to separate an aluminum frame and timber surround, this blade can cut through both types of materials. A standard reciprocating saw blade might break or quickly go blunt performing this kind of work.

These U.S.-made blades are 9 inches long with 5 TPI and sold in packs of five. To limit flex, they’re thicker than standard and heat treated to increase durability and stay sharp longer.

Best for Cast Iron

LENOX Tools Reciprocating Saw Blade, Diamond Grit 

See It

Cast iron is one of the most difficult materials to saw. While carbide-tipped blades can do the job, nothing competes with a diamond-coated blade, such as this 8-inch blade from Lenox, for speed and precision.

Rather than high carbon steel, Lenox uses a harder chrome-steel alloy, which allows for a thinner blade and narrower kerf without sacrificing strength. With a diamond coating, the reciprocating saw blade can cut even the hardest materials. It produces minimal vibration and leaves a smooth finish. While primarily designed for cast iron, the Lenox blade also can cut tile, brick, and even marble.

Best for Yard Work
