StewMac Ball Bearing Router Bit for Cavity Routing, 3/8" Diameter

Special bit for templates! Extra-long caroffere-tipped router bit produces 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 3/8\" cutter is recommended only for routing corners that need the tighter radius, and 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 using this 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 your re-chuck in the bit into your router. This will greatly extend the life of the bearings and reduces the risk of a bearing \"blow-out.\"
