Default Center finder for drilling round stock

In a lot of my projects I need to drill holes in round stock that are centered on the diameter. Iíve tried many methods and usually end up centering the drill bit by eye. Sometimes I do well and some times not so much. It is especially a problem with small diameter stock.

I found this nifty little tool at Micromark.com that has solved the problem for me no matter what diameter stock Iím using. Whether itís as small as quarter inch brass rod or larger wooden dowels, it is easy to center the drill bit. Just center the stock under the chuck with the jig. Lock the stock in position and then replace the jig with the appropriate sized bit and drill. Very simple.

The tool is relatively inexpensive and worth a look If you occasionally need to drill holes in round stock.

Hereís a link to the product: Center Finder for Round Stock

Thanks Oliver. That will work for doing metal with my milling machine too.

Someone I consider a master woodworker once told me that a master woodworker is not someone who never makes mistakes. He is someone who is able to cover them up so that no one can tell.

Nice tool, but an approximation.
And use fixturing to hold the work so it can be re-indexed.
If you have the luxury, drill in scrap rod first; see if that is close enough.
If not, then re-arrange your fixturing.

Thanks, I thought I'd bought everything I wanted for the shop, but I was wrong.

I don't normally recommend Harbor Freight, but they carry this nicely done fixture for holding round stock for drilling.

I dont see how that harbor frieght jig is SELF centering.

You have to decide where the plate is going to be bolted down every time.

How does it compare with this centering jig from Lee Valley?
