Designed for routers and routing tables alike, this bit is built to handle template-driven work with steady control. The combination of solid carbide and a down cut spiral helps produce smooth edges and reduces tear-out along the grain, especially when working with layered materials and composites.

How It Helps Your Projects

• Precise flush trimming: achieve clean, flush surfaces on hardwoods, laminates, plywood, particle board, solid surfaces, and composites.
• Template following: ideal for duplicating shapes and following templates, especially when the template sits above the workpiece on a router table.
• Stable routing: the double bearings offer additional stability, which can reduce bearing wear and produce steadier cuts over time.

What you can expect in real use: a confident cut with crisp edges, reduced grain tear-out, and smooth finishes on varied materials. The bit’s geometry aims to balance aggressive material removal with refined, professional results—useful for trim work, inlay boundaries, and edge profiling in a home shop or small professional shop.

Whiteside’s manufacturing heritage focuses on durability, precision, and thoughtful design. This bit is crafted for reliable performance in both handheld use and router-table setups, pairing well with a range of Whiteside or compatible accessories. To maximize life, keep bearings clean and ensure proper collet tightening before each run.
