Description
Rounding Over Bits
Rounding over bits are the most used of all the edge forming router bits. They are used for just breaking the sharp edge on a job as well as cutting decorative edging to form drop leaf joints. (Matching jointing bits are the Cove Bits.) Fitted with Mark free 12.7 x 4.8mm (B105) ball bearing guide these bits tend not to burn the work surface. The bit can also be converted into Beading bits just by changing to a smaller bearing (B106). The ball bearing fitted very close to the bottom cutting edge so as to allow full round over cut to be made with the bearing just being guided along a very narrow flat section on the bottom of the job. (the round over section just feathering out) Not many manufactures pay enough attention to this very important specification demanded by the tradesman.
All TruaCuT shaped bits have the full body Anti-Kickback design. Combined with close fitted bearings. ie. No large gap between the cutting edge & bearing.
