Overview
Belin production router bits for plastics and wood are solid-carbide, single O-flute upcut tools on a 1/4" shank. The polished single O-flute evacuates chips quickly, which helps keep plastics from re-welding and gives a clean edge, and Belin designs them with a reduced cut length for maximum rigidity and less vibration.
Choose the cutting diameter and length of cut to match material thickness: 1/8" cut with 1/2" LOC (13317) for fine detail in thin sheet, 3/16" with 5/8" LOC (13476) as an all-rounder, 3/16" with 1-1/4" LOC (13476B) for thicker stock, and 1/4" with 3/4" LOC (13635) for faster profiling of thicker acrylic, PVC and wood. Keep LOC just longer than the material to maximize rigidity.
Pair with our Duratex cast acrylic, Palight PVC, Gatorfoam, Duna HDU and MDO panels. Note: Belin became part of LMT Onsrud as of January 1, 2026; LMT Onsrud part-number cross-references exist for these tools (for example 13635 to 63-115).
