StewMac Ball Bearing Router Bits

StewMac Ball Bearing Router Bits Set of 2 0565

Special bits for templates! Extra-long carbide-tipped router bits produce clean, precise body cavities when used with routing templates. The ball-bearing guide matches the cutting diameter, and the long shank allows multiple-pass routing for deep cavities. The 1/2 inch diameter bit is recommended for most of your routing chores, and comes with 1 bearing. Use the 3/8 inch cutter only for routing corners that need the tighter radius, it comes with 2 bearings. Shank diameter: 1/4 inch (6.35mm) Cutting height: 1/2 inch (12.7mm) A heat-resistant sleeve (not shown) holds the bearing in position. This will greatly extend the life of the bearings and reduces the risk of a bearing “blow-out”.
