4" Air Saw Cutting Blades | 18 TPI | 24-Tooth | 1 Dozen (12-Pack)

These are 4-inch replacement cutting blades with 18 teeth per inch (TPI) and 24 teeth total, sold in a 1-dozen (12-blade) pack under SKU S527. Designed for use with 4" air reciprocating saws, they produce smooth, fine cuts in thin sheet metal, aluminum, plastic, and thin-wall tubing for professional autobody and fabrication applications.

18 TPI blades are optimized for cutting thin materials including sheet metal panels, aluminum sheet, thin-wall tubing, fiberglass, and plastic. The fine tooth pitch reduces burring and produces smooth cut edges. They are not recommended for cutting thick steel stock or hardwood, where lower TPI blades (14 TPI or lower) would be more appropriate.

These blades are used in autobody panel replacement, HVAC ductwork cutting, aluminum sheet trimming, thin-wall tubing cuts, fiberglass body work, and light sheet metal fabrication. Their 18 TPI configuration excels where smooth, clean edges are required on thin materials, especially in automotive restoration and body shop environments.

Yes. These 4" cutting blades are designed to fit standard 4-inch air reciprocating saw models. Always verify blade mounting compatibility with your specific saw model. The S527 blades are stocked by Creative Coating Solutions as a professional replacement supply for shops using 4" air saws in production cutting operations.

Higher TPI means more teeth per inch, producing finer, smoother cuts at slower cutting speeds. 18 TPI is ideal for thin sheet metal and aluminum. 16 TPI offers a balance of speed and finish for medium-thickness materials. 14 TPI cuts faster and more aggressively, suited for thicker metals or higher-speed cutting where edge finish is less critical.

Each purchase of the 4" 18 TPI Cutting Blades (S527) includes 1 dozen, which equals 12 blades per pack. This multi-pack format provides a cost-effective supply for professional shops that consume blades regularly in production cutting operations, reducing per-blade cost compared to individual purchases.
