4" Scroll Cutting Blades 14 TPI - 1 Dozen (S539)

14 TPI scroll blades are best for curved and contoured cuts in thin sheet metal, aluminum, plastic, and composite panels. The medium-fine tooth count produces cleaner edges than 10 TPI while cutting faster than blades above 18 TPI, making it a versatile choice for auto body and decorative fabrication.

14 TPI produces a smoother, finer cut than 10 TPI on thin materials. It is slightly slower but leaves a much cleaner edge on sheet metal and aluminum. Choose 14 TPI (S539) when surface quality matters, and 10 TPI (S538) for faster, more aggressive cutting on thicker stock.

14 TPI scroll blades perform well on thin sheet metal (up to about 1/8 inch), aluminum sheeting, HDPE and other plastics, fiberglass panels, and lightweight composites. They produce clean contoured cuts with minimal burring on these materials.

Yes. S539 blades are specifically suited for curved cuts in auto body panels. The 4-inch length and 14 TPI tooth profile allow the blade to track tight arcs and circles in body steel while maintaining a clean cut edge that requires minimal finishing work.

These 4-inch scroll blades are compatible with pneumatic air-powered reciprocating saws and select scroll saw attachments that accept a standard tang shank. Verify blade clamp compatibility with your specific tool before use.

For most auto body panel work involving thin steel (16–20 gauge), 14 TPI (S539) delivers a cleaner cut edge with less cleanup needed. For thicker panels or faster production cutting, 10 TPI (S538) may be preferable. Both are available in convenient dozen packs.

One order of S539 includes a full dozen (12) 4-inch 14 TPI scroll cutting blades, offering professional shops a bulk supply for consistent scroll and contour cutting operations.
