- Optimized for fine straight cuts in hardwood, softwood, plywood, OSB, and plastics - one blade profile handles a wide range of common workshop and job-site materials, reducing the need to swap blade types mid-project.

Why This Product
- The 10 TPI fine-tooth geometry is specifically suited for users who need straight, clean cuts through hardwood, softwood, plywood, OSB, and plastics - materials that range from 1/8 to 1 1/4 inches thick - without sacrificing edge quality.
- The universal T-Shank fits all major jig saws, meaning these blades integrate directly into your existing cordless or corded jig saw without requiring an adapter or replacement tooling.
- HCS construction provides the right balance of flexibility and cutting speed for wood-based and plastic materials, reducing the risk of blade breakage during controlled, fine straight-cut operations.
- Buying in a 5-piece pack provides immediate access to spare blades, keeping projects moving when one blade reaches the end of its service life - especially useful on high-volume cutting tasks in plywood or OSB panels.
