I inherited some odd bits. I've been told they are plunge pattern bits. The point is used to plunge through the material, then follow a pattern on the smooth shank. Above? Below? Both?
I am just wondering if anyone has experience using these bits and could tell me the pros and cons
The orange one is a 1/2" CMT carbide tipped bit, the small ones are 1/4" HSS.
I have heard they are used in the R.V. industry to cut windows holes etc. in the finished aluminum skinned, insulated panels...
I also have a regular 1/2" (bottom bearing?) pattern bit which I have used and the Robo-Sander pattern following sanding drum for the drill press which I have used to great effect!
