Set of 25 GRAPHITE jigsaw blades, model 57H770-25, equipped with a standardized T-shank and a 12 TPI (teeth per inch) tooth pitch. These blades are designed for general woodworking and DIY projects, offering a balance between cutting speed and finish quality. The T-shank ensures secure, tool-free mounting in compatible jigsaws that accept T-shank blades.
Advantages
The set provides consistent blade geometry across 25 identical pieces, reducing downtime for blade changes and ensuring repeatable results. A 12 TPI tooth pitch delivers medium-tooth performance suited to a range of wood types and composite materials, combining efficient material removal with acceptable edge finish. The T-shank design provides stable clamping in modern jigsaws, improving tracking and reducing blade wobble during cuts.
Suitable for
- Straight and curved cuts in soft and medium-density wood
- General carpentry and joinery tasks
- DIY projects and home renovation where a balance of speed and finish is required
- Cutting laminates and certain wood-based panels (with care to avoid chipping)
Key specifications
- Quantity: 25 blades per set
- Shank type: T-shank for compatible jigsaws
- Tooth pitch: 12 teeth per inch (12 TPI)
- Intended material: wood and similar wood-based materials
How to use
Install the blade into a T-shank compatible jigsaw according to the jigsaw manufacturer's instructions, ensuring the blade teeth face the material and the clamp is securely tightened. Select an appropriate cutting speed and feed rate for the material—slower feed for harder or brittle materials to reduce chipping, faster feed for softer woods to improve progress. Keep steady, even pressure and allow the blade to do the cutting without forcing it; replace blades when they show signs of wear or diminished cutting quality.
Usage recommendations
For best results, match the 12 TPI blades with medium-to-fine finishing tasks and use appropriate supports and clamping to prevent vibration. When cutting veneered or laminated panels, consider masking the cut line to reduce splintering. Wear suitable personal protective equipment, such as eye protection and dust mask, and follow safe operation guidelines for your jigsaw.
