The set includes a broad compatibility range, working with Bosch, DeWalt, Black & Decker, Makita, Ryobi, and others that use the T-shank design. These blades are suited for detailed interior patterns, letter cuts, and decorative scrollwork where clean edges are critical.
Diablo Bi-Metal Jig Saw Blades for Wood – 3-1/4″, 20 TPI
Diablo’s bi-metal blades combine durability with optimized tooth geometry for fast, smooth cuts in wood. The 3-1/4″ length and 20 TPI provide clean finishes on scroll cuts and intricate profiles. The ultra-hardened cutting edge extends blade life for repeated use in demanding woodworking tasks. These blades are particularly effective in scrollwork, inlays, and fine-edge projects where blade stiffness and tooth life translate into consistent performance.
TAROSE 30-Piece T101AO 3-1/4 Inch 20 TPI Assorted Blades
TAROSE offers a broad 30-piece assortment organized for compatibility with most common jigsaws. The set includes multiple T101AO blades with 20 TPI designed for clean wood cuts, plus several other profiles to cover straight cuts and downcut requirements.

Bosch T-Shank Jig Saw Blade Set T503
This three-piece Bosch set includes two T101BF blades optimized for clean hardwood cuts and one T101AOF blade tailored for laminate. Built with bi-metal construction, these blades emphasize durability for straight and curved cuts in hardwood and laminated flooring. The T503 assortment is particularly suitable for flooring installation projects where controlled, parallel cuts and minimal edge chipping are essential.
LENOX TOOLS 1991404 U-Shank Scroll Cutting Jigsaw Blade Trio
Lenox’s 3-pack U-shank blades are designed for smooth scroll cutting with a narrow profile that clears tight curves. The teeth are precision-ground to optimize cutting angles and reduce edge burning, making them a reliable choice for intricate patterns and flooring patterns. While compatible with U-shank tools, these blades remain a solid option for many modern jigsaws that support U- and some adapter configurations for broader compatibility.
Buying Guide: Key Purchase Considerations
- Blade compatibility: Check your jigsaw’s shank type (T-shank is most common; U-shank may require adapters). Confirm blade width and length for the intended cut radius.
- Tooth design and TPI: 20 TPI blades provide fine cuts with smoother edges and less splintering on wood. For laminate or plywood, select sharpened or specially coated blades to minimize chipping.
- Material and construction: Bi-metal blades offer longer life for tough materials, while high-carbon steel blades are often more affordable for light-duty work.
- Application: For tight curves and scrolling, prioritize blades with narrow bodies and pointed teeth. For straight cuts in hardwood, choose blades designed for durability and stability.
- Blade life and maintenance: Lubrication and proper feed speed extend blade life. Avoid twisting or bending the blade during cuts to reduce wear.
- Set contents: Consider blade assortment sets if you switch tasks frequently, as a single project may require multiple blade profiles and tooth types.
- Brand and warranty: Reputable brands often provide consistent geometry and sharper teeth, with warranties that cover manufacturing defects or early wear.
Choosing the right 20 TPI jigsaw blade depends on the material, cut type, and desired finish. For curved and decorative work, the 20 TPI blades from Bosch, Diablo, TAROSE, and Lenox offer a balance of edge quality, durability, and compatibility across popular jig saws. For laminate and hardwood, look for blades specifically optimized for straight cuts and clean finishing. A well-rounded blade set can cover most woodworking tasks—from precise scroll work to precise edge finishes—without constant blade changes.
