4" Reciprocating Cutting Blades 32 TPI - 1 Dozen (S533)

32 TPI blades are best for ultra-thin sheet metal, stainless steel, and precision cuts where minimal burring is critical. The very fine tooth pitch makes them ideal for delicate auto body work, intricate panel trimming, and any cut that demands a clean, smooth edge.

Yes. A higher TPI number means more teeth per inch, resulting in a finer, smoother cut. 32 TPI cuts slower than 24 TPI but produces a much cleaner edge on very thin materials. Use 32 TPI when surface finish and accuracy matter more than cutting speed.

These S533 blades use a standard reciprocating saw shank compatible with most air-powered pneumatic reciprocating saws. Confirm blade clamp compatibility with your specific model before use.

32 TPI blades perform best on metals thinner than 1/8 inch, including 18–22 gauge sheet steel, thin-wall tubing, and body panel stock. Using them on thicker material is possible but will reduce blade life and cutting efficiency.

These blades excel at auto body panel cuts, HVAC sheet metal work, precision trim cuts in tight areas, and stainless sheet fabrication. The 4-inch length gives better maneuverability in confined spaces compared to longer blades.

32 TPI is the finest option in this line, producing the smoothest edge but cutting more slowly than 24 or 18 TPI. Choose 32 TPI for ultra-thin metal and finish work, 24 TPI for general fine cutting, and 18 TPI for faster cuts on thicker stock.

Each S533 purchase includes one dozen (12) 4-inch 32 TPI cutting blades. Buying a full dozen reduces per-unit cost and keeps high-use shops continuously stocked with precision blades.
