## Recommended Router Bit

Choosing the right bit matters as much as choosing the right guide.

### J601 Up-Cut Spiral Bit
A reliable, proven choice for general woodworking and everyday circular cuts. Produces clean results in solid wood, plywood, and MDF.

### J603TT Double-T Compression Bit
Recommended for furniture-grade work and other high-value or visible materials, including speaker openings, where clean edges on both faces of the cut matter. Especially useful when working with solid hardwoods, veneered panels, or finished surfaces.

## Upgrade for Furniture-Grade Results

For projects where surface quality matters — such as tabletops, decorative discs, or other visible components — a finish-focused upgrade can help preserve the surface of the cut-out piece.

### Furniture Finish Upgrade Bundle
Includes the J603TT Double-T Compression Bit and the M350 Blemish-Free Pivot Plate, packaged together for convenience.

By eliminating a traditional point-style pivot, the M350 helps prevent center-point marks on the finished disc — ideal when the cut-out itself is the final piece.

This upgrade enhances results for furniture makers and builders working with high-value materials, without changing how the guide itself is used.

M350 Blemish-Free Pivot Plate

The M350 replaces a traditional point-style pivot pin when cutting full circular discs. By eliminating a center-point pivot hole, it helps preserve the surface of finished discs such as tabletops, cutting boards, and decorative panels.

## Standard vs PRO Version

**Standard Version**  
Designed for most woodworking and speaker-building projects, offering the same accuracy Jasper is known for.

**PRO Version**  
Made from premium polycarbonate for maximum durability and long working life — ideal for frequent use, demanding shop environments, or anyone who wants a virtually unbreakable tool.

---

## Circle Capacity

Cuts small to medium circles with consistent accuracy.

For larger circles (panels, tabletops, furniture parts), a larger-capacity Jasper guide may be a better fit.
