SELECTING GUIDE FOR RECIPROCATING SAW BLADE
                     SELECTING GUIDE FOR 
RECIPROCATING SAW BLADE
HOW TO SELECT THE RIGHT BLADE 
FOR A RECIPROCATING SAW?
Reciprocating saws are one of the foremost 
versatile tools available. A part of that versatility 
comes from the vast array of blades available for 
cutting through a good range of materials. With the 
proper blade, a saw can traverse wood, fiberglass, 
plaster, masonry, and metals, including aluminum, 
cast iron, steel, and even high-strength alloys. 
BLADE MATERIAL
• High Steel (HCS)
Carbon steel blades are the main inexpensive type and also 
the foremost common. They're the softest of the blade 
materials and tend to be more flexible to permit bending 
without breaking within the proper application. That also 
makes them the smallest amount durable. 
• High-Speed Steel (HSS)
High-speed steel blades are made with a tempering 
process that creates them more heat-resistant and sturdy 
than their steel counterparts. These blades last up to five 
times longer than steel blades. The hardness of the HSS 
blades makes them less flexible and thus more 
susceptible to breaking when bent. 
• Bi-Metal
Bi-Metal Blades include a high-carbon steel body for 
flexibility and break resistance and hot-work steel teeth for 
heat resistance, hardness, and sturdiness. Bi-metal 
blades last ten times longer than steel blades. While the 
value slightly quiets HSS or HCS blades, they provide 
flexibility and toughness for more demanding applications. 
• Carbide-Tipped
Carbide-tipped Sawzall blades also are bi-metal blades, 
but with a carbide (tungsten carbide or titanium carbide) 
tip at the top of every tooth. These carbide blades are 
tough, heat-resistant, and impact-resistant. They also 
offer 20 times the cutting life of a typical bi-metal blade.
• Carbide Grit
Carbide grit blades (typically tungsten carbide) do not have 
teeth, sort of a traditional Sawzall blade. They need an abrasive 
strip used for cutting dense materials like ceramic tile, cement, 
brick, marble, other stone, and masonry. The carbide grit's 
hardness allows it to chop these materials without damaging 
them or wearing them out prematurely.
• Diamond
Diamond blades also are abrasive but use diamonds rather than 
carbide. These are the foremost expensive saber saw blades. 
They're used to cut concrete, glass, fiberglass, and ceramic and 
cut fiber cement, cast iron, and masonry. The hardness of 
diamonds and the abrasive grit's fineness are essential to 
chopping brittle material like glass and hard and dense material 
like concrete.
