A particular advantage to this replacement tip style over the conventional brazed variety is that the diameter remains constant. These double and single flute style flush trim router cutters are designed for use on template and pattern work and can be used in hand-held and table-mounted routers. They have a shank mounted bearing which will run along and follow the template which is attached to the workpiece with the end result being an exact duplicate of the template itself.
The L209-OH tip has one cutting edge and is non reversible, the others are reversible. Tips are sold in boxes on 10.
