What does a cleaning bottom bit actually do?

It flattens and smooths the bottom of machined pockets, grooves, and dados. The flat-bottom, up-cut spiral design clears chips upward for a clean, level surface. Woodworkers use it for finishing inlays, mortises, and CNC pockets in cabinetry or signs.

Will this fit my router or CNC collet?

The bit has a 6mm shank, so you'll need a 6mm collet or a matching reducer. The cutting diameter is 8mm. Check your spindle's collet size before ordering so it seats properly.

What materials can it cut and how is it built?

It works on wood, MDF, and plastics. The carbide construction holds a sharp edge and resists wear through repeated cleaning passes. The solid shank stays rigid to limit deflection during heavier surfacing work.
