I have a couple of cheap Chinese 123 blocks with holes- half of them tapped to 3/8" and the other half through holes. One would imagine in some logical universe the through holes would accept a 3/8" bolt, but no- they are slightly smaller.
I want to use some existing tee nuts in the table and drop a bolt through, so I tried to drill one out- no go.
Is there some easy way to drill these out, or should I toss the POS and buy some that will work? I do not want to spend the time to set up on the mill, center every hole, and use an end mill. Will a straight flute carbide drill bit self center in the holes with no clamping?
I know this is stupid- I mean, one broken bit and it is the cost of some new blocks... But still, curious if it would work- I have drilled thousands of holes on the drill press without clamping to the table, just letting the entire vise and part float so the drill would self center- just have no idea if a carbide straight flute would do this.
