StewMac Ball Bearing Router Bits, Set of 2

Special bits for templates! Extra-long caroffere-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\" diameter bit is recommended for most of your routing chores, and comes with 1 bearing. Use the 3/8\" cutter only for routing corners that need the tighter radius, it comes with 2 bearings.Shank diameter: 1/4\" (6.35mm)Cutting height: 1/2\" (12.7mm)A heat-resistant sleeve (not shown) holds the bearing in position. We recommend stacking an extra bearing on the shank for deep cavities, and use the 3/8\" bit only for routing corners.Tip: We recommend that you change the position of stacked bearings on the router bit\'s shank every time you re-chuck the bit into your router. This will greatly extend the life of the bearings and reduces the risk of a bearing \"blow-out\".
