Jigsaw Guide: Mastering Curved and Intricate Cuts

Jigsaws cut curves that straight-cutting saws can't handle. From kitchen worktop cutouts to intricate scrollwork, they're essential for many tasks.

When to Use a Jigsaw

Jigsaws excel at:

• Curved cuts
• Cutouts in panels (sinks, sockets)
• Intricate shapes
• Cutting to marked lines
• Materials too thick for multi-tools

Key Features

Features that matter in jigsaw selection:

• Orbital action: Adjustable for different materials and cut quality
• Variable speed: Essential for different materials
• Blade change: Tool-free systems save time
• Dust blower: Keeps cut line visible
• Base tilt: For bevel cuts

Blade Selection

Blades determine cut quality:

• T-shank vs U-shank: T-shank is now standard
• TPI (teeth per inch): Higher = finer cut, lower = faster cut
• Blade material: HSS for wood, bi-metal for mixed materials
• Down-cutting blades: Reduce tearout on surface

Cutting Techniques

For clean cuts:

• Mark lines clearly on the good face
• Start slowly, let blade reach full speed
• Don't force the cut - let the blade do the work
• Support the workpiece to prevent vibration
• Use orbital action for faster cuts, zero orbital for cleaner ones

Making Plunge Cuts

To cut in the middle of a panel:

1. Drill a starter hole inside your cutout area
2. Or: Tilt the jigsaw forward on the base
3. Start the blade
4. Slowly lower into the material
5. Level out and continue cutting

Reducing Tearout

Jigsaws cut on the upstroke, causing tearout on the top surface:

• Place good face down
• Use down-cutting blades
• Score the cut line with a knife
• Apply masking tape along the cut

Corded vs Cordless

Cordless jigsaws from DeWalt and Makita offer plenty of power for most tasks. The improved manoeuvrability makes them worth considering even if you have a good corded model.
