- Be sure to keep the black bearing washer right side up to correspond with the bearing rotation when reassembling the bearing. Improper reassembly can cause the bit to unscrew. All CMT roundover bits have a 12,7mm (1/2″) bearing diameter with the exception of the radius 28,6mm (1-1/8″) and 31,7mm (1-1/4″) bits which have a 19mm (3/4″) bearing diameter. You have 13 different radii to choose from, the majority having 5 shank diameter options. All bits are made of Fatigue Proof® steel and have carbide-tipped cutting edges.
- The CMT 1,6mm (1/16″) radius roundover bit is excellent for finishing laminates. Virtually eliminates the filing required when using conventional trim bits.
- Use caution when working with large diameter bits and make more than one pass to gradually remove stock. Pay particular attention when routing small pieces; always rout on a router table equipped with a fence.
- Items featuring radius from 25,4mm (1″) to 38,1mm (1-1/2″) are to be used only on router table.
