Shank Cleaning Bottom Engraving Router Bit

This solid carbide router bit is designed for woodworkers who need clean bottom surfaces on grooves and engravings. The 18 mm cutting diameter suits detailed milling in solid wood, plywood, density board and particleboard. Industrial users gain a durable tungsten steel cutter that maintains sharpness through repetitive routing tasks.

Replaces worn or undersized straight bits

Upgrade when an existing bit leaves tear-out on the groove floor or cannot reach the required 18 mm width. The right-angle drill geometry improves chip evacuation in dense materials, so the jump is worthwhile for production runs where finish quality reduces downstream sanding time.

Fits standard 6 mm collets

Installation is a simple collet change; no shank adapters are required. Common issues include excessive feed rates that overheat the carbide and insufficient clamping depth that lets the bit pull out. Keep the tool restricted to users over 18 and follow industrial cutting guidelines to avoid premature wear.

Questions about this item

What shank diameter does the 18 mm router bit need to fit my collet?

The cutter has a 6 mm shank, so it fits any standard 6 mm collet or chuck on a rotary tool or CNC spindle.

How do I install the bit without damaging the solid-carbide flutes?

Insert the shank fully into the collet, tighten evenly, and avoid side loads during the first plunge to prevent chipping the cutting edges.

When should I replace the bit after cutting abrasive materials like particleboard?

Replace it when the carbide edges show visible rounding or when cut quality degrades on plywood and density board.
