It is a smaller version of screwing a piece of wood to the rip fence on a table saw.
I'm glad to hear this and have been waiting.

I use the sacrificial back plate when drilling it keeps the bit from drilling into the table and it works as a chip breaker so the holes are clean on both sides.

I dont recommend Harbor Freight many times but they sell a very good set of center drills 5 in a set.
I cant recommend these things enough for anyone that uses a drill press milling machine or lathe for putting starter holes where the need to be.
Rule of thumb is to only drill to about 2/3rds of the 60 degree shoulder on the bit.

They can also be used as a counter sink.
