1/8" Down-Cut Bit — Small Diameter, Clean Top Surface Every Pass

The 1/8" Down-Cut Bit pulls chips downward for a splinter-free top surface, handling everything from slotting to profiling without chip-out — the go-to size for detail and joinery work.

Solid carbide construction means it stays sharp through high-volume runs, so it holds up whether you're running one project or fifty.
