18 mm Solid Carbide Router Bit for Cleaning Bottom

This 18 mm tungsten-steel router bit is built for woodworkers who need a dedicated cleaning-bottom engraving tool. It cuts wood, plywood, density board, solid wood and particleboard with a solid-carbide milling profile. The right-angle drill format suits CNC and hand-router setups alike. Industrial-grade construction means it withstands repetitive production runs.

Shank Fit and Break-In Procedure

The bit installs directly into any compatible right-angle drill chuck or collet that accepts the shank diameter. No adapters or specialised collets are required beyond standard tool-holding hardware. First-time users should run a light test pass on scrap material to verify concentricity and avoid vibration. Over-tightening the collet or feeding too aggressively on the initial cut are the most common causes of premature edge wear.

Material Thickness and Machine Compatibility Check

Confirm your workpiece thickness allows the 18 mm cutting length to engage fully without bottoming out on the spoil board. Verify that your router or drill spindle delivers the RPM range recommended for solid-carbide tooling in the listed wood types. Ensure the machine’s Z-axis travel accommodates the overall bit length plus clearance for chip evacuation. Buyers needing longer reach or a different cutting diameter will need a separate tool.

Questions about this item

How can I verify the bit is cutting cleanly on the bottom surface after installing it?

Run the bit on a test piece of plywood or solid wood and inspect the bottom face for smooth, tear-free cuts.

What comes in the package and what extra items are required?

The package contains the solid carbide router bit only; a compatible router or CNC machine with an 8 mm collet must be supplied separately.

Which size should I choose for my project?

The bit has an 18 mm cutting diameter; select it when that width matches the groove or profile you need to mill.
