Jasper 603TT Compression Router Bit

Exceptional Edge Quality Starts Here

Accurate diameter deserves exceptional edge quality.

The Jasper 603TT Compression Router Bit is engineered to produce exceptionally clean top and bottom edges while minimizing tear-out in plywood, veneered panels, premium hardwoods, and MDF.

Whether you're routing speaker cutouts, driver recesses, furniture components, templates, decorative circles, or inlays, the 603TT is designed to help produce finish-ready results with less sanding and cleanup.

Designed to Complete the Jasper Precision Routing System

The Jasper 603TT isn't simply another router bit.

It was selected to complement Jasper Precision Routing Systems by producing exceptionally clean edges after the circle diameter has been established by your Jasper circle guide.

The result is a routing system engineered to produce circles that require less sanding, less cleanup, and a more professional finished appearance.

Ideal For

• Speaker cutouts

• Driver recesses

• Premium hardwoods

• Plywood

• Veneered panels

Why Choose a Compression Router Bit?

Compression geometry combines an up-cut lower section with a down-cut upper section, shearing cleanly from both faces of the workpiece to help minimize tear-out on both the top and bottom edges.

AP Nano Coating

The AP Nano coating helps reduce friction and heat while extending tool life.

Laboratory testing has demonstrated tool life up to 2.5× longer than comparable uncoated bits under similar cutting conditions.
