Drill Bits

Although drill bits come in specific sizes, not all 3/8″ bits do the same thing!

Brad Point Bit
The Brad Point bit (also known as lip and spur bit) is a precision drill bit.  Due to it’s sharp point on the end, it makes it easy to be more exact in your drilling.  This is my drill bit of choice.  If I have it on the drill press, it’s easy to spot right where the bit will make contact and bore, without it dancing around on the wood first.

 

Forstner Bitforstner_mancaveinvaded
These are another precision bit.  They are the precision bit equivalent to the spade bit.  If you need to drill out a larger hole, with a nice finish, this would be your best option.  Often used to drill holes for cabinet hardware installation.

 

Spade Bitspade_bit_Mancaveinvaded
Spade bits are not a precision bit.  Although they do have the sharp tip, they don’t act like a brad point bit.  The spade bit is often used for rough jobs.  It is very common to see a lot of splintering when you use one of these.  Not a bit you’ll have much use for if you have a forstner bit set.

 

Countersink  Bitcountersink_bit_mancave
Some projects it’s nice to have the screw inset into the wood, instead of visible.  The way to get that look is with a countersink bit.  This bit would be used with a standard screw.  Notice how the screw head shape and the countersink bit shape match.  The screw will sit nice inside your countersinked hole.

 

Counterbore Bitcounterbore_bit
Does the same job as the countersink bit.  Difference is, it leaves a flat surface on the bottom.  Compare the shape of the two.  While the countersink is a slanted shape, the counterbore is flat.  If you are willing to buy the ______ screws, and you want your screw to fit down in flush, you should opt for the counterboring bit.
